Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly useful for the SSD1306. Fixes #1828.

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. Hook up the terminal based on the first display. 2019-01-31T19:42:14+00:00 Scott Shawcroft scott@tannewt.org 2019-01-26T00:59:18+00:00 urn:sha1:1a1dbef992442682413f6103e36440a26bc2dad7 External fourwire works and blinka splash after 2019-01-17T08:20:16+00:00 Scott Shawcroft scott@tannewt.org 2019-01-17T08:20:16+00:00 urn:sha1:84292ad89070f1994ed09b59c8a693216a40cd89 Rework displays in prep for dynamic support and 8bit parallel. 2019-01-16T20:05:20+00:00 Scott Shawcroft scott@tannewt.org 2019-01-16T20:04:42+00:00 urn:sha1:05d8885a1ab959fabdbb77f99408b2e7dc78b97c Introduce displayio to render graphics to displays. 2018-08-31T19:31:52+00:00 Scott Shawcroft scott@tannewt.org 2018-08-15T18:01:01+00:00 urn:sha1:6697544cdf87d0df5b761d401ad6ffe3a8d752fc It's designed to minimize RAM footprint by using Sprites to represent objects on the screen. The object model also facilitates partial screen updating which reduces the bandwidth needed to display. This is all handled in C. Python simply manipulates the objects with the ability to synchronize to frame timing.
