Allocate the pixel memory for the bitmap, given its dimensions and colortype.
Return true on success, where success means either setPixels or setPixelRef was called. If the colortype requires a colortable, it also must be installed via setColorTable. If false is returned, the bitmap and colortable should be left unchanged.
Implemented in SkBitmap::HeapAllocator.
