Miro Kropacek 1870433daf BACKENDS: ATARI: Refactor & optimize dirty rects
This was long overdue. From my observation dirty rects don't need much
care, usually game engines already prepare them in a good shape (no
overlapping).

Also the overhead of calling the rect version of C2P isn't as big as I
was fearing, 256 64x64 rectangles are blitted roughly as quickly
as blitting one 1 MB block.

Removal of the rects traversal significantly speeds up Eco Quest for
instance.
