-// Known Issues:
-//
-// * Patterns are not implemented.
-// * 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)
-// * Optimize. There is always room for speed improvements.
