Summary Implement blend mode for accelerated canvas with Core Graphics

When cgcontext is created with an IOSurfaceRef instead of a CGBitmapContext, certain blend modes either don't work or work incorrectly. Wrong blend modes: color-burn and color-dodge Non working mode: hue, color, saturation and luminosity To reproduce, drop attached file in LayoutTests/fast/canvas/script-tests and run the test. You can also reproduce by opening ayoutTests/fast/canvas/canvas-blend-solid.html in webkit and make sure that accelerated canvas is enabled in the debug menu.

The fix for this issue was outside of the WebKit Open Source project.
