280aefffb7 IncrementalEncoder: Re-add missing update of quarter_count 
This lost line caused incremental encoders to stay stuck at 0 forever.

I seem to have lost it while trying to create tidy commits :frown:

78089107bc displayio.Bitmap: Allow modification though the buffer protocol 
It is required to call .dirty() with appropriate arguments after modifications through the buffer protocol, or the display might not be updated correctly.

f5fd42c393 displayio: Move bitmap read-only checking to displayio_bitmap_set_dirty_area 
This is a modest code savings, but more importantly it reduces
boilerplate in bitmap-modifying routines.

Callers need only ensure they call displayio_bitmap_set_dirty_area in
advance of the bitmap modifications they perform.

(note that this assumes that no bitmap operation can enter background
tasks. If an operation COULD enter background tasks, it MUST re-dirty
the area it touches when it exits, simply by a fresh call to
set_dirty_area with the same area as before)

36d608aa67 displayio_bitmap_set_dirty_area: rewrite in terms of displayio_area 
.. simplifying code in the process.  For instance, now fill_region
uses area routines to order and constrain its coordinates.

Happily, this change also frees a modest amount of code space.

f40c0c13ad displayio: area: add displayo_area_copy_coords, displayio_area_empty 
.. and simplify the implmentation of displayio_area_union

This _slightly_ changes the behavior of displayio_area_union:

Formerly, if one of the areas was empty, its coordinates were still
used in the min/max calculations.

Now, if one of the areas is empty, the result gets the other area's coords

In particular, taking the union of the empty area with coords (0,0,0,0)
with the non-empty area (x1,y1,x2,y2) would give the area (0,0,x2,y2)
before, and (x1,y1,x2,y2) after the change.

9133b23a37 bitmaptools: Add readinto 
When reading uncompressed bitmap data directly, readinto can work
much more quickly than a Python-coded loop.

On a Raspberry Pi Pico, I benchmarked a modified version of
adafruit_bitmap_font's pcf reader which uses readinto instead of
the existing code. My test font was a 72-point file created from Arial.

This decreased the time to load all the ASCII glyphs from 4.9 seconds to
just 0.44 seconds.

While this attempts to support many pixel configurations (1/2/4/8/16/24/32
bpp; swapped words and pixels) only the single combination used by
PCF fonts was tested.
