2019-02-11A variety of displayio improvementsScott Shawcroft
This changes a number of things in displayio: * Introduces BuiltinFont and Glyph so the built in font can be used by libraries. For boards with a font it is available as board.TERMINAL_FONT. Fixes #1172 * Remove _load_row from Bitmap in favor of bitmap[] access. Index can be x/y tuple or overall index. Fixes #1191 * Add width and height properties to Bitmap. * Add insert and [] access to Group. Fixes #1518 * Add index param to pop on Group. * Terminal no longer takes unicode character info. It takes a BuiltinFont instead. * Fix Terminal's handling of [###D vt100 commands used when up arrowing into repl history. * Add x and y positions to Group plus scale as well. * Add bitmap accessor for BuiltinFont
2019-02-01Add support for display rotation and raw commandsScott Shawcroft
Display rotation is relative to the scan order of the display. The scan order can be found by scrolling the display with command 0x37 `display_bus.send(0x37, struct.pack(">H", i % 128))` Fixes #1504

2018-08-31Introduce displayio to render graphics to displays.Scott Shawcroft
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.
