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.

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. Add index and remove to Group. 2019-05-15T18:33:16+00:00 Scott Shawcroft scott@tannewt.org 2019-05-15T18:33:16+00:00 urn:sha1:5608e273a01d0c39d2f82c695eec860288afa4a8 Make Group iterable via a generic native iterator. 2019-05-14T22:15:23+00:00 Scott Shawcroft scott@tannewt.org 2019-05-14T22:15:23+00:00 urn:sha1:b7b55e0c0a0187f4d248d9b52cd972af5d928336 Fixes #1694 Merge pull request #1883 from tannewt/fix_1881 2019-05-14T19:30:44+00:00 Dan Halbert halbert@adafruit.com 2019-05-14T19:30:44+00:00 urn:sha1:d3ce9280e2c00d62c327b25edc271d4ca97c4fae Check native object in case of early access Update Palette.c 2019-05-14T13:03:34+00:00 Matt Land matt-land@users.noreply.github.com 2019-05-14T13:03:34+00:00 urn:sha1:0b1c1c1d929352c9995bcb1e58e90309d89b9d38 Remove None, add in byte and bytearray examples Check native object in case of early access 2019-05-14T00:31:30+00:00 Scott Shawcroft scott@tannewt.org 2019-05-14T00:31:30+00:00 urn:sha1:f29de5132562cd6e88661d150fa1ee3ab8b771e1 If a native displayio object is accessed before it's super().__init__() has been called, then a placeholder is given that will cause a crash if accessed. This is tricky to get right so we detect this case and raise a NotInplementedError instead of crashing. Fixes #1881
