+// * 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)
