Bugzilla #47311:

Added an initial set of extensions for prepress support (fox:bleed, fox:crop-offset, fox:crop-box and fox:scale). This is currently supported only by PDF and Java2D renderers.
Submitted by: Peter Coppens <pc.subscriptions.at.gmail.com>

Changes to patch by jeremias:
- crop box expands from trim box rather than the bleed box.
- fixed positioning in AWT preview

Additional changes included:
- disabled the border around every page in Java2DRenderer.
- if background painting is enabled for the Java2DRenderer, it uses the bleed box rather than the trim box.

+            The crop box controls how Acrobat displays the page (CropBox in PDF) or how the Java2DRenderer sizes
+            the output media. The PDF specification defines that the CropBox defaults to the MediaBox. This extension
+            follows that definition. To simplify usage and cover most use cases, the three supported enumeration
+            values "trim-box", "bleed-box" and "media-box" set the CropBox to one of those three other boxes. 
+          </p>
+          <p>
+            If requested in the future, we could offer to specify the CropBox in absolute coordinates rather
+            than just be referencing another box.
