| Perspective Texture Mapping

Notes:

- If the texture is too dark to see, rerun the program.
  The texture is a plasma randomly generated every time.

Details:

- 100% Turbo Pascal, no inline assembly.

- 100% floating point, no fixed point.

- No sub-pixel or sub-texel accuracy
  (explains why texture jumps around).

- Unoptimized.  No gouraud interpolation every X pixels,
  just pure perspective texture.

Purpose:

- Just to see how difficult the algorithm I made up
  would be to program, and if 1/Z=constant (the magic
  3D formula) was actually true.
  It was never intended to be optimized in assembly.
