and a sparse bitmap for tracking which areas got updated.
This allows sprites to be rendered independently to their own
bitmap and then mixed in a final step. Converted the Sega

steps out of the sprite implementations and into the driver-

Added some further methods and helpers to the bitmap_t and
rectangle classes. [Aaron Giles]
Created a sega_16bit_common_base class which handles the
common Sega palette RAM mappings and open bus reads.
