still missing a few bits here and there but we need a break from
dry exercise and wanna do some pending app update field work instead :P
also it's good to debug a bit in situ too

It doesn't exist in CPython.

It's not implemented there.

Pass stream=True, as otherwise raw.read does not work.

Pass "Accept-Encoding: identity" header, as otherwise raw.read
can be compressed.

This makes sure it gets drawn after reenabling even if FPS value did not
change.

The old bounding box does not cover the case when all the icons
are visible (Wi-Fi enabled while charging), leading to artifacts.

Since 18f17883, a drawn frame is
guaranteed to reach the screen in a timely manner regardless of whether
the next think call will block for longer or not, so there's no need
to queue additional frames to make sure the animation has visibly
ended before dispatching _done callbacks anymore.

This makes the rendering code clear the whole screen on first frame.
This is needed because the framebuffer may be filled with content from
previous mpy boot after a soft reboot, leading to possible artifacts.

Increase maximum edge list to 1024 elements, double the maximum number of
segments per-scanline.

Better resource management for smart-redraws, API change - dropped argument
in pixel_update callback for smart redraws. Use optimized hairline renderer
for <= 0 line_width. Correct AA for scanlines ending in horizontal scanline,
optimizations for rasterizer.

Got lost in a rebase.

note: for accurate absolute altitude calculation we'd need to know the local
pressure at sea level, outside temperature and ideally relative humidity.
while it is certainly possible to retrieve them via wifi etc., it is not in
the scope of this application to do so.

relative altitude is proportional to outside temperature, so we introduce a
multiplicative error by ignoring it. this scale error is 7% at 35degC and
-4% at 0degC. in comparison, if we assume the temperature reading is the
outside temperature, going from a heated apartment to the balcony at same
elevation can cause a shift that may well be in the magnitude of 10m. we
find the former to be preferable to the latter.
