Updates the handling of perspective quads to calculate the correct, degenerate-safe projected quad and then derive from that the proper perspective quad. In 2D, updated to determine if the optimized outset/inset procedure is valid, and if not goes through a more robust procedure that is based on line equation intersections. In particular, the degenerate inset/outset approach is used when the quad has a zero-length edge, if insetting/outsetting normally would create a self-intersecting shape, or if near parallel edge angles would create numerical instabilities. Performance testing by forcing all rectangle draws through the degenerate code path suggests that it is about 10% slower than the optimal approach, at least on my workstation...
