Different operations to the display tree have different costs. Be aware of these costs when optimizing your code. * Changing tiles indices in a TileGrid will update an area covering them all. * Changing a palette will refresh every object that references it. * Moving a TileGrid will update both where it was and where it moved to. * Adding something to a Group will refresh each individual area it covers. * Removing things from a Group will refresh one area that covers all previous locations. (Not separate areas like add.) * Setting a new top level Group will refresh the entire display. Only TileGrid moves are optimized for overlap. All other overlaps cause sending of duplicate pixels. This also adds flip_x, flip_y and transpose_xy to TileGrid. They change the direction of the pixels but not the location. Fixes #1169. Fixes #1705. Fixes #1923.
