I am thinking of taking advantage of the fact that we store the  
"original" texture data as well as the VRAM version.  The way I am  
thinking of using this is for the palette based textures.  Something  
along the lines of old DOS mode 13 graphics (256 color, etc).  I have  
most of these changes in an older version of Tiki already but need to  
promote them to the latest.

If it is wasting space on the PC it will waste space on the DC likely  
as well.
