2019-07-19Fix it's -> itsScott Shawcroft
2019-07-18Track a dirty area for in-memory bitmapsScott Shawcroft
This fixes the bug that bitmap changes do not cause screen updates and optimizes the refresh when the bitmap is simply shown on the screen. If the bitmap is used in tiles, then changing it will cause all TileGrids using it to do a full refresh. Fixes #1981

2019-06-12Add partial display update support.Scott Shawcroft
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.

2019-05-31Fix off-by-one errorScott Shawcroft
It caused the bottom and right edges to be one pixel short.
2019-05-22Make point 2 in areas exclusive and simplify full_coverage.Scott Shawcroft
2019-05-21Rework the pixel computation to use areasScott Shawcroft
This changes the displayio pixel computation from per-pixel to per-area. This is precursor work to updating portions of the screen (#1169). It should provide mild speedups because bounds checks are done once per area rather than once per pixel. Filling by area also allows TileGrid to maintain a row-associative fill pattern even when the display's refresh is orthogonal to it.
