This header file should only contain self-contained constants (no dependencies). C++ const is preferred to use type-checking but some must be defined as some source files test them using if.

NOTE: Be sure to WRITE A PERIOD IN FLOAT CONSTANTS defined by define or integer instructions could be compiled (with loss of accuracy).

NOTE: Don't overflow 32-bits (esp. in BSP constants).

The kinds of Polygons is limited to triangles and quads. Limiting to only triangles would be ideal (guarantees planar polygons), but modeling some Objects in terms of quads is convenient.
