Fix bugs from previous

Fix stray triangles
- Switch to full floating point RTPS/RTPT
- Clamp w values to near plane

Fix texture corruption in 1.78, copy 2.4 Tweak
- Remove matrix replacement
- Add W component to vertices
- Wrap glVertex3fv calls
- Use counter to call glVertex4fv for PGXP vertices only
