This procedurally builds all of the textures.

I apologize in advance for the apalling state of this module. It's the victim
|
|
|
|
of iterative and experimental development. It has cruft, poorly named
|
2009-05-05 08:41:05 +01:00
|
|
|
functions, obscure code, poorly named variables, and is badly organized. Even
|
2009-05-03 12:05:03 +01:00
|
|
|
the formatting sucks in places. Its only saving grace is that it works.
