 * HTexture handler for texture functions
 *
 * $Log: not supported by cvs2svn $
 *
 * 12    8/30/99 12:55p Gwar
 * added a parameter to HTexturePropagateToFace to not change the texture
 * of the target face
 *
 * 11    5/19/99 12:21a Gwar
 *
 * 10    4/27/99 3:30p Gwar
 * added a NEWEDITOR #define
 *
 * 9     8/15/98 5:04p Matt
 * Added code to copy a texture & UVs from one face to another
 *
 * 8     4/16/98 10:42a Matt
 * Made texture propagation work across rooms.
 *
 * 7     9/17/97 11:57a Matt
 * Ripped out segment code
 *
 * 6     9/17/97 11:17a Samir
 * BIG SEGMENT RIPOUT
 *
 * 5     8/13/97 9:52a Matt
 * Combined slide left/right/up/down into one function, and the same with
 * rotate left/right
 *
 * 4     8/01/97 4:53p Jason
 * made a more general PropagateTextureToFace function call
 *
 * 4     4/17/97 4:03p Samir
 * Apply Tmap 1 and Tmap2 implemented, but no Tmap2 rendering is occurring
 * yet.
 *
 * 3     3/31/97 3:50p Samir
 * Set default texture uvs should work for side not whole segment.
 *
 * 2     2/26/97 3:59p Samir
 * Most scaling, rotating, sliding and flipping work.
