Fix a bunch of rendering bugs.
- 'clear' polarity primitives no longer erase background - Added aperture macro support for polygons - Added aperture macro rendring support - Renderer now creates a new surface for each layer and merges them instead of working directly on a single surface - Updated examples accordingly
