Textures are now showing up somewhat correctly!
Most of the actual changes are on the data conversion side.

Made polygon building faster by checking ahead of time if we have enough primitive buffer space, instead of checking it per polygon.
Also the primitive buffer management is now all done through inline functions.

Fixes to make things work on real hardware again:
- Struct pointers need to be 32-bit aligned, otherwise the PS1 will crash
- For this purpose, some structs have been padded to make them a multiple of 4 bytes in size
- Vector data needs to be copied into scratch RAM at a 32-bit aligned address

Implemented PVS decompression, leaf visibility check using PVS data, and front-to-back traversal of the BSP tree.

Rewrote scratchpad function to work more as I envisioned it:
sequential calls will pass on a variable to each other that gets updated with the new offset position in the scratch buffer.

First simple test with scratch memory, just to verify that it works.

Set up some helper functions for memory management, including scratchpad memory. Moved the primitive buffer here too.
This will probably have to become inline functions or macros at some point, but for now it's just pure C.
