Mat Booth 04a655c744 extmod/modframebuf: Add polygon drawing methods. ...

Add method for drawing polygons.

For non-filled polygons, uses the existing line-drawing code to render
arbitrary polygons using the given coords list, at the given x,y position,
in the given colour.

For filled polygons, arbitrary closed polygons are rendered using a fast
point-in-polygon algorithm to determine where the edges of the polygon lie
on each pixel row.

Tests and documentation updates are also included.
