- Clean up PolyTriangleDrawer API so that it can better support both softpoly and the swrenderer

- Slightly improve how softpoly processes portals
- Pass the vertex transform matrix via a command rather than being part of the drawer args
- Improve zbuffer drawers in the software renderer
- Misc model rendering fixes
