Display API change:
- getTile -> startTile (no longer returns a tile)
- setSubTile -> subTile (drop img/tile first parameter)
- putTile -> finishTile (no longer takes img/tile paramter)
The Display tile logic uses canvas image data directly and
caches/reuses a 16x16 imageData tile (for other sizes, the tile is
create for each call). This gives a 30% speedup on Chrome
13 (and no significant change for Firefox 3.6/4.0).
Other:
- Remove rgbxImageFill and cmapImageFill routines.
- Simplify constructor tests and just error if createImageData is not
supported by canvas instead of .
- Remove webkit canvas bug workaround that effects Chrome 7. Chrome
7 usage share is now less than 0.5 percent and the workaround is
ugly. Drop the function wrapping in the constructor and the canvas
flush() routine.
- Remove support for getImageData (Opera 11+ now required)
Update browser support list:
- Chrome 8+ (really any except 7)
- Firefox 3.6+
- Safari 4+
- Opera 11+
- IE9+
- iOS 4.2+
