Previously, both mask and clip-path were rendered to separate mutable Gfx::Bitmap objects which forced CPU rasterization. They were then combined using a CPU pixel-by-pixel operation before being returned as an ImmutableBitmap. Instead of including mask in the final bitmap as already rasterized images, we now use display lists which opens opportunity to utilize GPU if available. Bitmap::apply_mask() and ApplyMaskBitmap display list command are no longer used and have been removed.
