Texmap render issues on PT

[Travis Cobbs]

Yes, of course each time they are loaded. Otherwise the frame rate might suffer quite a bit

When the TEXMAP spec was created, a conscious decision was made to favor ease of authorship over ease of rendering. It is expected that anyone with the knowledge to write a renderer also has the knowledge to scale the textures as-needed for their renderer to work. This is also why the TEXMAP spec specifies projected textures instead of UV-mapped textures.
