|
|

//
|
|
||||
// * 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)
|
|

// * Non uniform scaling does not correctly scale strokes.
