* Removes VectorShape from user python interactions
* Re-integrates vectorio with displayio behind draw protocol implementations
* Implements draw protocol with VectorShape
* Composes VectorShape behaviors into Rectangle, Circle and Polygon
* Fixes terrible pixel garbage being left behind
* Improves redraw performance (heuristically) by tracking dirty area separately from current area.
Known Issues:
It does not work with transposed views.
This is a breaking change with previous palette semantic with respect to python code that uses vectorio.
Displayio has breaking changes in cpy 7 for Group's removal of max_size parameter so this is as good a
time as any to break everything.
Currently:
To color vectorio shapes correctly you have to pass in a palette with length 2. Palette[0] must be set transparent and palette[1] must be the color you want.
New:
To color vectorio shapes correctly you pass in a palette with length >= 1. Palette[0] will be the color of the shape.
Also improves pixels per second when skipping areas that aren't covered by the shape.
Passing in a PWMOut still works but is deprecated. It will be
removed in CircuitPython 8.0.0
This also switches STM32 timer indices and channel indices to
0-based in our pin data rather than `- 1` everywhere. The latter is
more bug prone.
Most of the way for #3264
Tested on Metro M0, Metro M4, Feather S2, Feather nRF52840, Feather
STM32F4 and Arduino RP2040.
INCOMPATIBLE CHANGE: struct_time(1,2,3,4,5,6,7,8,9) is now _rejected_
just as on standad Python.
This incorrect constructor was added by me in #2327; I assumed
without even checking that the `struct_time` constructor was also
compatible with the `namedtuple` constructor, but it is not and has
always been rejected by standard Python (checked 2.7 and 3.9)
This commit restores the specific error message that we used for this
purpose, which was removed in the previous commit either out of laziness
or out of trying to reduce unneeded error strings. In this case, the
alternate string is too misleading (it refers to arguments, not to
sequence elements) so let's put the better message back.
