Kenny 8607cdd783 vectorio: add draw protocol
* 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.
