Of course !
You know I was initially thinking about the efficiency of a "generic"
Texture management.
But sure that my sprites sheet are correctly set in images with
"optimized" dimensions.

I was just wondering about the usefulness of gluBuild2DMipMaps in such
a context.
I just noted through some newsgroups and opengl related forums that
this function was really often called
by the developpers.
