[Gtkradiant] some results on texture compression

I ran some memory usage tests on my GeForce3 under Win2k:

- 1.2.10 and 1.2.11 have the same 30Mb VM size at start

- 1.2.10 loading SoF2's airport set, 600Mb

- 1.2.11 loading Sof2's airport set:
GL_ARB 122Mb
DXT1   78 Mb
DXT3   122Mb
DXT5   122Mb

Huge difference with 1.2.10 obviously. DXT1 seems to be the more 
compressive method, but the rendering of the texture is broken here. I'd 
be curious to know if anyone gets broken texture rendering for any 
compression combo.
