Phil Howard a2e6a8838e PicoVector: AF: Support for 16bit point count. 
Somewhere in the conversion from C++ to C we lost support for 16-bit point counts.

Raise the internal point count to 16-bit, and check for a flag in the font.

If the flag is set, treat the point count as 16-bits, otherwise fallback to 8 for back compatibility.

Phil Howard 219b93c90b PicoVector: Initialise pp_transform(). 
For some reason this was unset causing drawing to fail.

Reset it to a known good state in the constructor.

Phil Howard 3f2bce2979 PicoVector: Fix bug in Polygon.rectangle. 
Fix spurious point in top-left corner causing a broken triangular

is rounded.

Phil Howard 515521c16c PicoVector: Avoid MicroPython GC. 
Since we're not using tracked allocation, any memory we don't explicitly
hold a reference to will be assumed unused by MicroPython's GC.

Pass up the pp_nodes and pp_node_counts points (hackily) to fix this.

pretty-poly.h is not giving us fully clipped rectangles, so revert to the

Phil Howard 3a9cdc8f39 PicoGraphics: Layers. 
Add preliminary support for multiple layered drawing surfaces.

Allows, for example, static content to be loaded into one layer and
remain unmodified while the above layer contains animations.

Particularly useful for drawing PNG or JPEG UI elements which are
then overdrawn with text or animated elements, without paying the
cost of loading/decoding every frame.

Phil Howard 19689b4414 PicoGraphics: Fix overflow bug in p4 pixel span. 
A properly aligned zero length pixel span would cause a single
pixel to be drawn, the length overflowed and a subsequent
2GB of pixels drawn by the main loop.

Add a simple check to discard any attempt to draw zero length spans.
