6.5.3.2.4 Mask Blit

Mask blit uses the bit stream from the command buffer. Each output pixel can be a combination of source, pattern, and destination.

For mask blit, the bit from the stream is used to toggle on/off a color in the source frame buffer. Mask blit takes its color source from memory and its pattern from the command stream.

Clipping is supported and is performed on a per-pixel basis.
