Bug 32738 makes SVG Mask faster. The pixel manipulation just performs on
creating the MaskResource and not on every applyMask() call. The mask
imageBuffer is as small as possible.
If applyMask() is still to slow, it's the problem of
GraphicsContext::clipToImageBuffer and we should ask the Cg folks to use HW
accelerators or perform better some how ;-)
