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
rectangle when any permutation of corners other than the bottom-left
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.

Phil Howard cc38cf06fb PicoVector: Revert the tile buffer to be fixed. 
Ensure that MicroPython doesn't ever place the tile buffer into PSRAM
and trash performance.

Phil Howard 230d9facab PicoVector: Refactor text multiline support. 
Drop dependence on null terminated strings, and for a final linebreak.

Bound all text processing using the text length.

Phil Howard d4e0d660b9 PicoVector: Big refactor, ppp primitives. 
* Remove Polygon types in favour of primitives .circle, .rectangle etc
* Add a new Transform type for building up transformation matrices
* Add support to set/clear transform on drawing
