Refactor deinit check to reduce code size. 2019-06-12 11:36:43 -07:00

Add partial display update support. 
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.

Rework the pixel computation to use areas 
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.

Standardize TileGrid to x and y properties over position 
This brings it inline with Group. Also fixes #1613

This also includes a number of fixes for where a method is called
through a subclass. We now correctly get the native object.
Fixes #1567

Lastly, this adds subscript support to TileGrid for changing tile
indices. Similar to Bitmap, it accepts ints or 2-tuples.

A safe mode fix and displayio fixes 
* Fixes safe mode on the SAMD51. The "preserved" value was being
clobbered by the bootloader.
* Fixes auto-reload loop when in safe mode.
* Fixes reading Group children with [].
* Check that a TileGrid actually moves before queueing a refresh.

A variety of displayio improvements 
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

Introduce displayio to render graphics to displays. 
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.
