Layer anti-aliasing

Patch implements anti-aliasing by adding transparent borders around layers and adjusting vertices to make sure we process all necessary fragments.

This approach handles tiled layers properly and produces smooth edges that match bi-linear filter output.

Known issues:
- Creates textures that are 1 or 2 pixels larger than the tile size.
- Makes the assumption that textures are initialized to transparent black.
