Isaac Connor e1eb7876c6 fix: clamp percentage polygon to width-1/height-1 ...

ParsePercentagePolygon clamped to [0, width] / [0, height], so a new
zone created at 100% produced pixel coords equal to the monitor
dimensions. The rasterizer requires hi_x < width and hi_y < height,
so the runtime then logged warnings like
  "polygon hi_x (1920) >= image width (1920), clamping".

Clamp to width-1 / height-1 instead. Updates existing tests that
encoded the previous behavior.
