Subject: Fixed a bug in the drawing of all the graphs, especially visible in easeout curves... 
X-Git-Tag: 1.8a2~117
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=afc26e41eba932e1c12dcd8a48cb6c90fd4dd679;p=jquery-ui.git

Fixed a bug in the drawing of all the graphs, especially visible in easeout curves. Added a top line to each graph. Added support for linear graph and preview. Slowed animation down a bit, to aid in preview.
