 ## Contributing
-All contributions are very welcome but please make sure you:
-
-- maintain the coding style
-  - __indentation__ of 2 spaces
-  - no tailing __semicolons__
-  - single __quotes__
-  - use one line __comments__ to describe any additions
-  - look around and you'll know what to do
-- __write at least one spec example per implementation or modification__
-
-Before running the specs you will need to build the library.
-Be aware that pull requests without specs will be declined.
+All contributions are very welcome but please make sure you follow the same coding style. Here are some guidelines.
+
+### Indentation
+We do it with __two spaces__. Make sure you don't start using tabs becaus then things get messy.
+
+### Avoid hairy code
+We like to keep things simple and clean, don't write anything you don't need. So use __single quotes__ where possible and __avoid semicolons__, we're not writing PHP here.
+
+__Good__:
+```javascript
+var text = draw.text('with single quotes here')
+  , nest = draw.nested().attr('x', '50%')
+
+for (var i = 0; i < 5; i++)
+  if (i != 3)
+    nest.circle(i * 100)
+```
+
+__Bad__:
+```javascript
+var text = draw.text("with single quotes here");
+var nest = draw.nested().attr("x", "50%");
+
+for (var i = 0; i < 5; i++) {
+  if (i != 3) {
+    nest.circle(100);
+  };
+};
+```
+
+### Let your code breathe people!
+Don't try to be a code compressor yourself, they do way better a job anyway. Give your code some spaces and newlines.
+
+__Good__:
+```javascript
+var nest = draw.nested().attr({
+  x:      10
+, y:      20
+, width:  200
+, height: 300
+})
+
+for (var i = 0; i < 5; i++)
+  nest.circle(100)
+```
+
+__Bad__:
+```javascript
+var nest=draw.nested().attr({x:10,y:20,width:200,height:300});
+for(var i=0;i<5;i++)nest.circle(100);
+```
+
+### It won't hurt to add a few comments
+Where necessary tell us what you are doing but be concise. We only use single-line comments. Also keep your variable and method names short while maintaining readability.
+
+__Good__:
+```javascript
+// Adds orange-specific methods
+SVG.extend(SVG.Rect, {
+  // Add a nice, transparent orange
+  orangify: function() {
+    // fill with orange color
+    this.fill('orange')
+
+    // add a slight opacity
+    return this.opacity(0.85)
+  }
+})
+```
+
+__Bad__:
+```javascript
+/*
+ *
+ * does something with orange and opacity
+ *
+ */
+SVG.extend(SVG.Rect, {
+  orgf: function() {
+    return this.fill('orange').opacity(0.85)
+  }
+})
+```
+
+### Test. Your. Code.
+It's not that hard to write at least one example per implementation although we prefer more. Your code might seem to work by quickly testing it in your brwoser but more than often you can't forsee everything.
+
+Before running the specs you will need to build the library. Be aware that pull requests without specs will be declined.

-<p>A lightweight library for manipulating and animating SVG.</p>
-<p>Svg.js has no dependencies and aims to be as small as possible.</p>

-<h3 id='usage/create-a-svg-document' id="create-a-svg-document">Create a SVG document</h3 id='usage/create-a-svg-document'>
-<p>Use the <code>SVG()</code> function to create a SVG document within a given html element:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> draw = SVG(<span class="string">'drawing'</span>).size(<span class="number">300</span>, <span class="number">300</span>)
-<span class="keyword">var</span> rect = draw.rect(<span class="number">100</span>, <span class="number">100</span>).attr({ fill: <span class="string">'#f06'</span> })</code></pre>
-<p>The first argument can either be an id of the element or the selected element itself.
-This will generate the following output:</p>
-<pre><code class="lang-html"><span class="tag">&lt;<span class="title">div</span> <span class="attribute">id</span>=<span class="value">"drawing"</span>&gt;</span>
-    <span class="tag">&lt;<span class="title">svg</span> <span class="attribute">xmlns</span>=<span class="value">"http://www.w3.org/2000/svg"</span> <span class="attribute">version</span>=<span class="value">"1.1"</span> <span class="attribute">xmlns:xlink</span>=<span class="value">"http://www.w3.org/1999/xlink"</span> <span class="attribute">width</span>=<span class="value">"300"</span> <span class="attribute">height</span>=<span class="value">"300"</span>&gt;</span>

-<span class="tag">&lt;/<span class="title">div</span>&gt;</span></code></pre>
-<p>By default the svg drawing follows the dimensions of its parent, in this case <code>#drawing</code>:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> draw = SVG(<span class="string">'drawing'</span>).size(<span class="string">'100%'</span>, <span class="string">'100%'</span>)</code></pre>
-<h3 id='usage/checking-for-svg-support' id="checking-for-svg-support">Checking for SVG support</h3 id='usage/checking-for-svg-support'>
-<p>By default this library assumes the client&#39;s browser supports SVG. You can test support as follows:</p>
-<pre><code class="lang-javascript"><span class="keyword">if</span> (SVG.supported) {
-  <span class="keyword">var</span> draw = SVG(<span class="string">'drawing'</span>)
-  <span class="keyword">var</span> rect = draw.rect(<span class="number">100</span>, <span class="number">100</span>)

-  alert(<span class="string">'SVG not supported'</span>)
-}</code></pre>
-<h3 id='usage/svg-document' id="svg-document">SVG document</h3 id='usage/svg-document'>
-<p>Svg.js also works outside of the HTML DOM, inside an SVG document for example:</p>
-<pre><code class="lang-xml"><span class="pi">&lt;?xml version="1.0" encoding="utf-8" ?&gt;</span>
-<span class="tag">&lt;<span class="title">svg</span> <span class="attribute">id</span>=<span class="value">"drawing"</span> <span class="attribute">xmlns</span>=<span class="value">"http://www.w3.org/2000/svg"</span> <span class="attribute">xmlns:xlink</span>=<span class="value">"http://www.w3.org/1999/xlink"</span> <span class="attribute">version</span>=<span class="value">"1.1"</span> &gt;</span>

-<p>By default sub pixel offset won&#39;t be corrected. To enable it, call the <code>fixSubPixelOffset()</code> method:</p>

-<h3 id='parent-elements/main-svg-document' id="main-svg-document">Main svg document</h3 id='parent-elements/main-svg-document'>
-<p>The main SVG.js initializer function creates a root svg node in the given element and retuns an instance of <code>SVG.Doc</code>:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> draw = SVG(<span class="string">'drawing'</span>)</code></pre>
-<p><strong><code>returns</code>: <code>SVG.Doc</code></strong></p>

-<h3 id='parent-elements/nested-svg' id="nested-svg">Nested svg</h3 id='parent-elements/nested-svg'>
-<p>With this feature you can nest svg documents within each other. Nested svg documents have exactly the same features as the main, top-level svg document:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> nested = draw.nested()
-
-<span class="keyword">var</span> rect = nested.rect(<span class="number">200</span>, <span class="number">200</span>)</code></pre>

-<h3 id='parent-elements/groups' id="groups">Groups</h3 id='parent-elements/groups'>
-<p>Grouping elements is useful if you want to transform a set of elements as if it were one. All element within a group maintain their position relative to the group they belong to. A group has all the same element methods as the root svg document:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> group = draw.group()
-group.path(<span class="string">'M10,20L30,40'</span>)</code></pre>
-<p>Existing elements from the svg document can also be added to a group:</p>
-<pre><code class="lang-javascript">group.add(rect)</code></pre>
-<p><strong>Note:</strong> Groups do not have a geometry of their own, it&#39;s inherited from their content. Therefore groups do not listen to <code>x</code>, <code>y</code>, <code>width</code> and <code>height</code> attributes. If that is what you are looking for, use a <code>nested()</code> svg instead.</p>
-<p><strong><code>returns</code>: <code>SVG.G</code></strong></p>
-<p><em>Javascript inheritance stack: <code>SVG.G</code> &lt; <code>SVG.Container</code> &lt; <code>SVG.Parent</code></em></p>
-<h3 id='parent-elements/hyperlink' id="hyperlink">Hyperlink</h3 id='parent-elements/hyperlink'>
-<p>A hyperlink or <code>&lt;a&gt;</code> tag creates a container that enables a link on all children:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> link = draw.link(<span class="string">'http://svgjs.com'</span>)
-<span class="keyword">var</span> rect = link.rect(<span class="number">100</span>, <span class="number">100</span>)</code></pre>
-<p>The link url can be updated with the <code>to()</code> method:</p>
-<pre><code class="lang-javascript">link.to(<span class="string">'http://apple.com'</span>)</code></pre>
-<p>Furthermore, the link element has a <code>show()</code> method to create the <code>xlink:show</code> attribute:</p>
-<pre><code class="lang-javascript">link.show(<span class="string">'replace'</span>)</code></pre>
-<p>And the <code>target()</code> method to create the <code>target</code> attribute:</p>
-<pre><code class="lang-javascript">link.target(<span class="string">'_blank'</span>)</code></pre>
-<p>Elements can also be linked the other way around with the <code>linkTo()</code> method:</p>
-<pre><code class="lang-javascript">rect.linkTo(<span class="string">'http://svgjs.com'</span>)</code></pre>
-<p>Alternatively a block can be passed instead of a url for more options on the link element:</p>
-<pre><code class="lang-javascript">rect.linkTo(<span class="keyword">function</span>(link) {
-  link.to(<span class="string">'http://svgjs.com'</span>).target(<span class="string">'_blank'</span>)

-<h3 id='parent-elements/defs' id="defs">Defs</h3 id='parent-elements/defs'>
-<p>The <code>&lt;defs&gt;</code> element is a container element for referenced elements. Elements that are descendants of a ‘defs’ are not rendered directly. The <code>&lt;defs&gt;</code> node lives in the main <code>&lt;svg&gt;</code> document and can be accessed with the <code>defs()</code> method:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> defs = draw.defs()</code></pre>
-<p>The defs are also availabel on any other element through the <code>doc()</code> method:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> defs = rect.doc().defs()</code></pre>
-<p>The defs node works exactly the same as groups.</p>

-<p>Rects can also have rounded corners:</p>
-<pre><code class="lang-javascript">rect.radius(<span class="number">10</span>)</code></pre>
-<p>This will set the <code>rx</code> and <code>ry</code> attributes to <code>10</code>. To set <code>rx</code> and <code>ry</code> individually:</p>
-<pre><code class="lang-javascript">rect.radius(<span class="number">10</span>, <span class="number">20</span>)</code></pre>
-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<h2 id='circle' id="circle">Circle</h2 id='circle'>
-<p>The only argument necessary for a circle is the diameter:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> circle = draw.circle(<span class="number">100</span>)</code></pre>
-<p><strong><code>returns</code>: <code>SVG.Circle</code></strong></p>

-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<h2 id='ellipse' id="ellipse">Ellipse</h2 id='ellipse'>
-<p>Ellipses, like rects, have two arguments, their <code>width</code> and <code>height</code>:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> ellipse = draw.ellipse(<span class="number">200</span>, <span class="number">100</span>)</code></pre>
-<p><strong><code>returns</code>: <code>SVG.Ellipse</code></strong></p>

-<pre><code class="lang-javascript">rect.radius(<span class="number">75</span>, <span class="number">50</span>)</code></pre>
-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<h2 id='line' id="line">Line</h2 id='line'>
-<p>Create a line from point A to point B:</p>

-<p>Creating a line element can be done in four ways. Look at the <code>plot()</code> method to see all the possiblilities.</p>
-<p><strong><code>returns</code>: <code>SVG.Line</code></strong></p>
-<p><em>Javascript inheritance stack: <code>SVG.Line</code> &lt; <code>SVG.Shape</code> &lt; <code>SVG.Element</code></em></p>

-<p>Alternatively it also accepts a point string:</p>
-<pre><code class="lang-javascript">line.plot(<span class="string">'0,0 100,150'</span>)</code></pre>
-<p>Or a point array:</p>
-<pre><code class="lang-javascript">line.plot([[<span class="number">0</span>, <span class="number">0</span>], [<span class="number">100</span>, <span class="number">150</span>]])</code></pre>

-<p>Polyline strings consist of a list of points separated by spaces: <code>x,y x,y x,y</code>.</p>
-<p>As an alternative an array of points will work as well:</p>
-<pre><code class="lang-javascript"><span class="comment">// polyline([[x,y], [x,y], [x,y]])</span>

-<h2 id='text' id="text">Text</h2 id='text'>
-<p>Unlike html, text in svg is much harder to tame. There is no way to create flowing text, so newlines should be entered manually. In SVG.js there are two ways to create text elements.</p>
-<p>The first and easiest method is to provide a string of text, split by newlines:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> text = draw.text(<span class="string">"Lorem ipsum dolor sit amet consectetur.\nCras sodales imperdiet auctor."</span>)</code></pre>
-<p>This will automatically create a block of text and insert newlines where necessary.</p>
-<p>The second method will give you much more control but requires a bit more code:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> text = draw.text(<span class="keyword">function</span>(add) {
-  add.tspan(<span class="string">'Lorem ipsum dolor sit amet '</span>).newLine()
-  add.tspan(<span class="string">'consectetur'</span>).fill(<span class="string">'#f06'</span>)
-  add.tspan(<span class="string">'.'</span>)
-  add.tspan(<span class="string">'Cras sodales imperdiet auctor.'</span>).newLine().dx(<span class="number">20</span>)
-  add.tspan(<span class="string">'Nunc ultrices lectus at erat'</span>).newLine()
-  add.tspan(<span class="string">'dictum pharetra elementum ante'</span>).newLine()
-})</code></pre>
-<p>If you want to go the other way and don&#39;t want to add tspans at all, just one line of text, you can use the <code>plain()</code> method instead:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> text = draw.plain(<span class="string">'Lorem ipsum dolor sit amet consectetur.'</span>)</code></pre>
-<p>This is a shortcut to the <code>plain</code> method on the <code>SVG.Text</code> instance which doesn&#39;t render newlines at all.</p>
-<p><em>Javascript inheritance stack: <code>SVG.Text</code> &lt; <code>SVG.Shape</code> &lt; <code>SVG.Element</code></em></p>
-<p><strong><code>returns</code>: <code>SVG.Text</code></strong></p>
-<h3 id='text/text' id="text-">text()</h3 id='text/text'>
-<p>Changing text afterwards is also possible with the <code>text()</code> method:</p>
-<pre><code class="lang-javascript">text.text(<span class="string">'Brilliant!'</span>)</code></pre>
-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<p>To get the raw text content:</p>
-<pre><code class="lang-javascript">text.text()</code></pre>
-<p><strong><code>returns</code>: <code>string</code></strong></p>
-<h3 id='text/tspan' id="tspan-">tspan()</h3 id='text/tspan'>
-<p>Just adding one tspan is also possible:</p>
-<pre><code class="lang-javascript">text.tspan(<span class="string">' on a train...'</span>).fill(<span class="string">'#f06'</span>)</code></pre>
-<p><strong><code>returns</code>: <code>SVG.Tspan</code></strong></p>
-<h3 id='text/plain' id="plain-">plain()</h3 id='text/plain'>
-<p>If the content of the element doesn&#39;t need any stying or multiple lines, it might be sufficient to just add some plain text:</p>
-<pre><code class="lang-javascript">text.plain(<span class="string">'I do not have any expectations.'</span>)</code></pre>
-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<h3 id='text/font' id="font-">font()</h3 id='text/font'>
-<p>The sugar.js module provides some syntax sugar specifically for this element type:</p>
-<pre><code class="lang-javascript">text.font({
-  family:   <span class="string">'Helvetica'</span>
-, size:     <span class="number">144</span>
-, anchor:   <span class="string">'middle'</span>
-, leading:  <span class="string">'1.5em'</span>
-})</code></pre>
-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<h3 id='text/leading' id="leading-">leading()</h3 id='text/leading'>
-<p>As opposed to html, where leading is defined by <code>line-height</code>, svg does not have a natural leading equivalent. In svg, lines are not defined naturally. They are defined by <code>&lt;tspan&gt;</code> nodes with a <code>dy</code> attribute defining the line height and a <code>x</code> value resetting the line to the <code>x</code> position of the parent text element. But you can also have many nodes in one line defining a different <code>y</code>, <code>dy</code>, <code>x</code> or even <code>dx</code> value. This gives us a lot of freedom, but also a lot more responsibility. We have to decide when a new line is defined, where it starts, what its offset is and what it&#39;s height is. The <code>leading()</code> method in SVG.js tries to ease the pain by giving you behaviour that is much closer to html. In combination with newline separated text, it works just like html:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> text = draw.text(<span class="string">"Lorem ipsum dolor sit amet consectetur.\nCras sodales imperdiet auctor."</span>)
-text.leading(<span class="number">1.3</span>)</code></pre>
-<p>This will render a text element with a tspan element for each line, with a <code>dy</code> value of <code>130%</code> of the font size.</p>
-<p>Note that the <code>leading()</code> method assumes that every first level tspan in a text node represents a new line. Using <code>leading()</code> on text elements containing multiple tspans in one line (e.g. without a wrapping tspan defining a new line) will render scrambeled. So it is advisable to use this method with care, preferably only when throwing newline separated text at the text element or calling the <code>newLine()</code> method on every first level tspan added in the block passed as argument to the text element.</p>
-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<h3 id='text/build' id="build-">build()</h3 id='text/build'>
-<p>The <code>build()</code> can be used to enable / disable build mode. With build mode disabled, the <code>plain()</code> and <code>tspan()</code> methods will first call the <code>clear()</code> bethod before adding the new content. So when build mode is enabled, <code>plain()</code> and <code>tspan()</code> will append the new content to the existing content. When passing a block to the <code>text()</code> method, build mode is toggled automatically before and after the block is called. But in some cases it might be useful to be able to toggle it manually:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> text = draw.text(<span class="string">'This is just the start, '</span>)
-
-text.build(<span class="literal">true</span>)  <span class="comment">// enables build mode</span>
-
-<span class="keyword">var</span> tspan = text.tspan(<span class="string">'something pink in the middle '</span>).fill(<span class="string">'#00ff97'</span>)
-text.plain(<span class="string">'and again boring at the end.'</span>)
-
-text.build(<span class="literal">false</span>) <span class="comment">// disables build mode</span>
-
-tspan.animate(<span class="string">'2s'</span>).fill(<span class="string">'#f06'</span>)</code></pre>
-<p><strong><code>returns</code>: <code>itself</code></strong></p>
-<h3 id='text/rebuild' id="rebuild-">rebuild()</h3 id='text/rebuild'>
-<p>This is an internal callback that probably never needs to be called manually. Basically it rebuilds the text element whenerver <code>font-size</code> and <code>x</code> attributes or the <code>leading()</code> of the text element are modified. This method also acts a setter to enable or disable rebuilding:</p>
-<pre><code class="lang-javascript">text.rebuild(<span class="literal">false</span>) <span class="comment">//-&gt; disables rebuilding</span>
-text.rebuild(<span class="literal">true</span>)  <span class="comment">//-&gt; enables rebuilding and instantaneously rebuilds the text element</span></code></pre>

-<h3 id='tspan/text' id="text-">text()</h3 id='tspan/text'>

-  .font({ size: <span class="number">42.5</span>, family: <span class="string">'Verdana'</span> })</code></pre>
-<p>When calling the <code>path()</code> method on a text element, the text element is mutated into an intermediate between a text and a path element. From that point on the text element will also feature a <code>plot()</code> method to update the path:</p>

-<p>The use element simply emulates another existing element. Any changes on the master element will be reflected on all the <code>use</code> instances. The usage of <code>use()</code> is very straightforward:</p>

-<p>In the case of the example above two rects will appear on the svg drawing, the original and the <code>use</code> instance. In some cases you might want to hide the original element. the best way to do this is to create the original element in the defs node:</p>

-<h3 id='manipulating-elements/transform' id="transform-">transform()</h3 id='manipulating-elements/transform'>
-<p>The <code>transform()</code> can act both as a getter or a setter. Let&#39;s start with the former but first a word about transforms.</p>
-<p>Transforms are cascading sequentially. Every transform you add will build further on the effects of all the previous transforms together. So for example, when you add the <code>translate(10, 10)</code> transform three times, the total translation will equal <code>translate(30, 30)</code>.</p>
-<p>We are going to use one node as an example for this section:</p>
-<pre><code class="lang-xml"><span class="tag">&lt;<span class="title">rect</span> <span class="attribute">width</span>=<span class="value">"100"</span> <span class="attribute">height</span>=<span class="value">"100"</span> <span class="attribute">transform</span>=<span class="value">"translate(10, 10) rotate(45, 100, 100) scale(0.5, 0.5) rotate(-10)"</span> /&gt;</span></code></pre>
-<h4 id="get-by-index">get by index</h4>
-<p>A transform at a specific index:</p>
-<pre><code class="lang-javascript">rect.transform(<span class="number">1</span>)
-<span class="comment">// -&gt; returns { type: 'scale', x: 0.5, cy: 0.5 }</span></code></pre>
-<h4 id="get-by-name">get by name</h4>
-<p>By default the first occurence of a given transform type will be returned:</p>
-<pre><code class="lang-javascript">rect.transform(<span class="string">'rotate'</span>)
-<span class="comment">// -&gt; returns { type: 'rotate', rotation: 45, cx: 100, cy: 100 }</span></code></pre>
-<p>If multiple occurences of a transform type exist they can be fetched with a number:</p>
-<pre><code class="lang-javascript">rect.transform(<span class="string">'rotate'</span>, { at: <span class="number">1</span> })
-<span class="comment">// -&gt; returns { type: 'rotate', rotation: -10 }</span></code></pre>
-<p>With the <code>transform()</code> method elements can be scaled, rotated, translated and skewed:</p>
-<pre><code class="lang-javascript">rect.transform({
-  rotation: <span class="number">45</span>
-, cx:       <span class="number">100</span>
-, cy:       <span class="number">100</span>
-})</code></pre>
-<p>You can also provide two arguments as property and value:</p>
-<pre><code class="lang-javascript">rect.transform(<span class="string">'matrix'</span>, <span class="string">'1,0.5,0.5,1,0,0'</span>)</code></pre>
-<p>Note that you can also apply transformations directly using the <code>attr()</code> method:</p>
-<pre><code class="lang-javascript">rect.attr(<span class="string">'transform'</span>, <span class="string">'matrix(1,0.5,0.5,1,0,0)'</span>)</code></pre>
-<p>Although that would mean you can&#39;t use the <code>transform()</code> method because it would overwrite any manually applied transformations. You should only go down this route if you know exactly what you are doing and you want to achieve an effect that is not achievable with the <code>transform()</code> method.</p>

-<h3 id='manipulating-elements/style' id="style-">style()</h3 id='manipulating-elements/style'>
-<p>With the <code>style()</code> method the <code>style</code> attribute can be managed like attributes with <code>attr</code>:</p>
-<pre><code class="lang-javascript">rect.style(<span class="string">'cursor'</span>, <span class="string">'pointer'</span>)</code></pre>
-<p>Multiple styles can be set at once using an object:</p>
-<pre><code class="lang-javascript">rect.style({ cursor: <span class="string">'pointer'</span>, fill: <span class="string">'#f03'</span> })</code></pre>
-<p>Or a css string:</p>
-<pre><code class="lang-javascript">rect.style(<span class="string">'cursor:pointer;fill:#f03;'</span>)</code></pre>
-<p>Similarly to <code>attr()</code> the <code>style()</code> method can also act as a getter:</p>
-<pre><code class="lang-javascript">rect.style(<span class="string">'cursor'</span>)
-<span class="comment">// =&gt; pointer</span></code></pre>
-<p>Or even a full getter:</p>
-<pre><code class="lang-javascript">rect.style()
-<span class="comment">// =&gt; 'cursor:pointer;fill:#f03;'</span></code></pre>
-<p>Explicitly deleting individual style definitions works the same as with the <code>attr()</code> method:</p>

-<h3 id='manipulating-elements/move' id="move-">move()</h3 id='manipulating-elements/move'>
-<p>Move the element to a given <code>x</code> and <code>y</code> position by its upper left corner:</p>
-<pre><code class="lang-javascript">rect.move(<span class="number">200</span>, <span class="number">350</span>)</code></pre>
-<p>Note that you can also use the following code to move some elements (like images and rects) around:</p>
-<pre><code class="lang-javascript">rect.attr({ x: <span class="number">20</span>, y: <span class="number">60</span> })</code></pre>
-<p>Although <code>move()</code> is much more convenient because it will always use the upper left corner as the position reference, whereas with using <code>attr()</code> the <code>x</code> and <code>y</code> reference differ between element types. For example, rect uses the upper left corner with the <code>x</code> and <code>y</code> attributes, circle and ellipse use their center with the <code>cx</code> and <code>cy</code> attributes and thereby simply ignoring the <code>x</code> and <code>y</code> values you might assign.</p>

-<p>The <code>viewBox</code> attribute of an <code>&lt;svg&gt;</code> element can be managed with the <code>viewbox()</code> method. When supplied with four arguments it will act as a setter:</p>
-<pre><code class="lang-javascript">draw.viewbox(<span class="number">0</span>, <span class="number">0</span>, <span class="number">297</span>, <span class="number">210</span>)</code></pre>

-<pre><code class="lang-javascript"><span class="keyword">var</span> box = draw.viewbox()</code></pre>
-<p>But the best thing about the <code>viewbox()</code> method is that you can get the zoom of the viewbox:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> box = draw.viewbox()
-<span class="keyword">var</span> zoom = box.zoom</code></pre>

-<p>As opposed to the native <code>getBBox()</code> method any translations used with the <code>transform()</code> method will be taken into account.</p>
-<p>The <code>SVG.BBox</code> has one other nifty little feature, enter the <code>merge()</code> method. With <code>merge()</code> two <code>SVG.BBox</code> instances can be merged into one new instance, basically being the bounding box of the two original bounding boxes:</p>

-<pre><code class="lang-javascript">rect.animate().move(<span class="number">150</span>, <span class="number">150</span>)</code></pre>
-<p>The <code>animate()</code> method will take three arguments. The first is <code>duration</code>, the second <code>ease</code> and the third <code>delay</code>:</p>

-<p>Note that <code>pos</code> is <code>0</code> in the beginning of the animation and <code>1</code> at the end of the animation.</p>
-<p>To make things easier a morphing function is passed as the second argument. This function accepts a <code>from</code> and <code>to</code> value as the first and second argument and they can be a number, unit or hex color:</p>

-<p>The <code>marker()</code> method can be used in three ways. Firstly, a marker can be created on any container element (e.g. svg, nested, group, ...). This is useful if you plan to reuse the marker many times so it will create a marker in the defs but not show it yet:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> marker = draw.marker(<span class="number">10</span>, <span class="number">10</span>, <span class="keyword">function</span>() {

-<p>Secondly a marker can be created and applied directly on its target element:</p>
-<pre><code class="lang-javascript">path.marker(<span class="string">'start'</span>, <span class="number">10</span>, <span class="number">10</span>, <span class="keyword">function</span>() {
-  add.circle(<span class="number">10</span>).fill(<span class="string">'#f06'</span>)
-})</code></pre>
-<p>This will create a marker in the defs and apply it directly. Note that the first argument defines the position of the marker and that there are four arguments as opposed to three with the first example.</p>
-<p>Lastly, if a marker is created for reuse on a container element, it can be applied directly on the target element:</p>
-<pre><code class="lang-javascript">path.marker(<span class="string">'mid'</span>, marker)</code></pre>

-<h3 id='marker/ref' id="ref-">ref()</h3 id='marker/ref'>

-<p>Matrices in SVG.js have their own class <code>SVG.Matrix</code>, wrapping the native <code>SVGMatrix</code>. They add a lot of functionality like extracting transform values, matrix morphing and improvements on the native methods.</p>

-<p>Creating your own custom elements with SVG.js is piece of cake thanks to the <code>SVG.invent</code> function. For the sake of this example, lets &quot;invent&quot; a shape. We want a <code>rect</code> with rounded corners that are always proportional to the height of the element. The new shape lives in the <code>SVG</code> namespace and is called <code>Rounded</code>. Here is how we achieve that.</p>
-<pre><code class="lang-javascript">SVG.Rounded = SVG.invent({
-  <span class="comment">// Define the type of element that should be created</span>
-  create: <span class="string">'rect'</span>
-
-  <span class="comment">// Specify from which existing class this shape inherits</span>
-, inherit: SVG.Shape
-
-  <span class="comment">// Add custom methods to invented shape</span>
-, extend: {
-    <span class="comment">// Create method to proportionally scale the rounded corners</span>
-    size: <span class="keyword">function</span>(width, height) {
-      <span class="keyword">return</span> <span class="keyword">this</span>.attr({
-        width:  width
-      , height: height
-      , rx:     height / <span class="number">5</span>
-      , ry:     height / <span class="number">5</span>
-      })
-    }
-  }
-
-  <span class="comment">// Add method to parent elements</span>
-, construct: {
-    <span class="comment">// Create a rounded element</span>
-    rounded: <span class="keyword">function</span>(width, height) {
-      <span class="keyword">return</span> <span class="keyword">this</span>.put(<span class="keyword">new</span> SVG.Rounded).size(width, height)
-    }
-
-  }
-})</code></pre>
-<p>To create the element in your drawing:</p>
-<pre><code class="lang-javascript"><span class="keyword">var</span> rounded = draw.rounded(<span class="number">200</span>, <span class="number">100</span>)</code></pre>
-<p>That&#39;s it, the invention is now ready to be used!</p>
-<h4 id="accepted-values">Accepted values</h4>
-<p>The <code>SVG.invent()</code> function always expectes an object. The object can have the following configuration values:</p>
-<ul>
-<li><code>create</code>: can be either a string with the node name (e.g. <code>rect</code>, <code>ellipse</code>, ...) or a custom initializer function; <code>[required]</code></li>
-<li><code>inherit</code>: the desired SVG.js class to inherit from (e.g. <code>SVG.Shape</code>, <code>SVG.Element</code>, <code>SVG.Container</code>, <code>SVG.Rect</code>, ...); <code>[optional but recommended]</code></li>
-<li><code>extend</code>: an object with the methods that should be applied to the element&#39;s prototype; <code>[optional]</code></li>
-<li><code>construct</code>: an objects with the methods to create the element on the parent element; <code>[optional]</code></li>
-<li><code>parent</code>: an SVG.js parent class on which the methods in the passed <code>construct</code> object should be available; <code>[optional]</code></li>
-</ul>
-<p>Svg.js uses the <code>SVG.invent()</code> function to create all internal elements, so have a look at the source to see how this function is used in various ways.</p>
-<h3 id='extending-functionality/svg-extend' id="svg-extend-">SVG.extend()</h3 id='extending-functionality/svg-extend'>
-<p>Svg.js has a modular structure. It is very easy to add you own methods at different levels. Let&#39;s say we want to add a method to all shape types then we would add our method to SVG.Shape:</p>
-<pre><code class="lang-javascript">SVG.extend(SVG.Shape, {
-  paintRed: <span class="keyword">function</span>() {
-    <span class="keyword">return</span> <span class="keyword">this</span>.fill(<span class="string">'red'</span>)
-  }
-})</code></pre>
-<p>Now all shapes will have the paintRed method available. Say we want to have the paintRed method on an ellipse apply a slightly different color:</p>
-<pre><code class="lang-javascript">SVG.extend(SVG.Ellipse, {
-  paintRed: <span class="keyword">function</span>() {
-    <span class="keyword">return</span> <span class="keyword">this</span>.fill(<span class="string">'orangered'</span>)
-  }
-})</code></pre>
-<p>The complete inheritance stack for <code>SVG.Ellipse</code> is:</p>
-<p><em><code>SVG.Ellipse</code> &lt; <code>SVG.Shape</code> &lt; <code>SVG.Element</code></em></p>
-<p>The SVG document can be extended by using:</p>
-<pre><code class="lang-javascript">SVG.extend(SVG.Doc, {
-  paintAllPink: <span class="keyword">function</span>() {
-    <span class="keyword">this</span>.each(<span class="keyword">function</span>() {
-      <span class="keyword">this</span>.fill(<span class="string">'pink'</span>)
-    })
-  }
-})</code></pre>
-<p>You can also extend multiple elements at once:</p>
-<pre><code class="lang-javascript">SVG.extend(SVG.Ellipse, SVG.Path, SVG.Polygon, {
-  paintRed: <span class="keyword">function</span>() {
-    <span class="keyword">return</span> <span class="keyword">this</span>.fill(<span class="string">'orangered'</span>)
-  }
-})</code></pre>
