using dot product for backface culling as a parameter of camera-to-face distance and angle.
Also includes face area as a parameter: the larger the face, the more subdivisions it'll need.
Visualizing this with colors, blended with the lighting data.
- 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
- Load map data using a macro, so I can easily change the implementation for all data chunks.
- Implemented a visdata function that loads all 1's, so that every leaf will be drawn.
- Point-to-plane distance now uses copies of input vectors. May or may not be faster.
- Fixed fps counter rounding and disabled vsync so we can see the true framerate
