Originally, black_bindings found each contiguous "//|" block and sent
it to black independently. This was slower than it needed to be.
Instead, swap the comment prefix: when running black, take off
"//|" prefixes and put "##|" prefixes on all un-prefixed lines.
Then, after black is run, do the opposite operation
This more than doubles the overall speed of "pre-commit run --all",
from 3m20s to 55s CPU time on my local machine (32.5s to under 10s
"elapsed" time)
It also causes a small amount of churn in the bindings, because
black now sees enough context to know whether one 'def' follows another
or ends the 'def's in a 'class'. In the latter case, it adds an extra
newline, which becomes a "//|" line.
I'm less sure why a trailing comma was omitted before down in
rp2pio/StateMachine.c but let's roll with it.
These diagnostics occurred, but weren't treated as errors:
```
[WARN] Missing return type: alphablend on line 38
[WARN] Missing argument type: dest_bitmap on line 38
[WARN] Missing argument type: source_bitmap_1 on line 38
[WARN] Missing argument type: source_bitmap_2 on line 38
```
mp_obj_float_get gets the value of an object, which must be
exactly a float. mp_obj_get_float gets the float value of
an object of various types, including floats & ints.
This blends two "565"-format bitmaps, including byteswapped ones. All
the bitmaps have to have the same memory format.
The routine takes about 63ms on a Kaluga when operating on 320x240 bitmaps.
Of course, displaying the bitmap also takes time.
There's untested code for the L8 (8-bit greyscale) case. This can be
enabled once gifio is merged.
Convert bitbangio, bitmaptools, _bleio, board, busio, countio, digitalio, framebufferio, frequencyio, gamepadshift, getpass, keypad, math, microcontroller, and msgpack modules to use MP_REGISTER_MODULE.
Related to #5183.
It is required to call .dirty() with appropriate arguments after modifications through the buffer protocol, or the display might not be updated correctly.
