Phil Howard fba0f1c962 PicoVector: Add tracked memory alloc, track the node buffer. 
With a low GC threshold the node buffer was being collected (despite guards against this)
and causing further drawing operations to be corrupted.

Add a new tracked malloc method and use it for node buffers and font data.

Tweak pp_poly_add_path to accept a point count, avoiding many successive rellocs when
dealing with a known quantity of points (copying from an af_glyph_t.)

Phil Howard d2728d4b06 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 78eb6da31b PicoVector: Remove * 4 from pp_nodes lookup. 2025-04-25 17:33:52 +01:00
Phil Howard 8d8b950308 PicoVector: Revert the tile buffer to be fixed. 
Ensure that MicroPython doesn't ever place the tile buffer into PSRAM
and trash performance.
