* texlist.c - textured-movie gset test
*
* example run:
* texlist -R [string of texture names]
* ex: texlist -R wood.rgb marble.rgb brick.rgba
*
* command line options:
* -R - come up running the movie
* -i - use the LIST_IDLE texture loading mode
* -r - use the LIST_SUBLOAD texture loading mode - continuously
* downloads texture from host
* -T use tiling to take offset portion of movie textures and
* map them to an offset destination
