draw_bmp: cosmetics, refactor

Mostly pedantic bikeshedding issues.

Move some code around, so that the sub_bitmap_to_mp_images() function
can be split into two parts. This is better than having a big function
with many input and outputs, of which only half are used in each code
path.

Also, try to make code simpler by using a mp_rect type.
