-// * 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.

-/* Plugin for jQuery for working with colors.
- * 
- * Version 1.1.
- * 
- * 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() return the same modified object
- * instead of making a new one.
- *
- * V. 1.1: Fix error handling so e.g. parsing an empty string does
- * produce a color rather than just crashing.

+
+/* Plugin for jQuery for working with colors.
+ * 
+ * Version 1.1.
+ * 
+ * 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() return the same modified object
+ * instead of making a new one.
+ *
+ * V. 1.1: Fix error handling so e.g. parsing an empty string does
+ * produce a color rather than just crashing.
