+// Known Issues:
+//
+// * Patterns only support repeat.
+// * Radial gradient are not implemented. The VML version of these look very
+//   different from the canvas one.
+// * Clipping paths are not implemented.
+// * Coordsize. The width and height attribute have higher priority than the
+//   width and height style values which isn't correct.
+// * Painting mode isn't implemented.
+// * Canvas width/height should is using content-box by default. IE in
+//   Quirks mode will draw the canvas using border-box. Either change your
+//   doctype to HTML5
+//   (http://www.whatwg.org/specs/web-apps/current-work/#the-doctype)
+//   or use Box Sizing Behavior from WebFX
+//   (http://webfx.eae.net/dhtml/boxsizing/boxsizing.html)
+// * Non uniform scaling does not correctly scale strokes.
+// * Filling very large shapes (above 5000 points) is buggy.
+// * Optimize. There is always room for speed improvements.

+/* Plugin for jQuery for working with colors.
+ * 
+ * Version 1.0.
+ * 
+ * Inspiration from jQuery color animation plugin by John Resig.
+ *
+ * Released under the MIT license by Ole Laursen, October 2009.
+ *
+ * Examples:
+ *
+ *   $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
+ *   var c = $.color.extract($("#mydiv"), 'background-color');
+ *   console.log(c.r, c.g, c.b, c.a);
+ *   $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
+ *
+ * Note that .scale() and .add() work in-place instead of returning
+ * new objects.
