Alrighty, let's give this another go...
This patch hasn't changed much. Just added bitmap_t, typedef'd to
unsigned long * for passing around bitmaps without breaking the
abstraction. I think it's good if we can keep the underlying data type
hidden to partially future-proof (protect? ;) the code.
Part 1/1 coming up...
Cheers!
