// 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
|
