demand to speed up things a bit. Used especially when using tiles,
layers or the whole tilemap bitmap. All get_X_bitmap methods you see are
used to retrieve bitmaps from cache.
2) The draw_layer and draw_tilemap methods have a rect argument. When
not nil, only the region specified by this rect is redrawn. Again, this
is to speed up the whole process.
I did some basic speed test using the Time class to see how log it takes
to blit a tile depending on the map size, using 32x32 tiles.

maybe some earlier hardware), but I cannot verify since I have
none.
I will reply with patches against the kernel, drm, ddx
and mesa for
