 Seems like i managed to fix it, but with dirty hack... see function in
attachment. tcl somehow is not aware of wind inverting, and i just inverted
commands, but it works that way :).

 This fbo test case works, fbotexture and tri-cull from mesa demos - with both
swtcl and tcl. What i tested, yeah Aquaria game is no more black with fbo usage
and also Supertuxkart now show icons in minimap, etc.

 Anyhow, maybe someone know how to make that better to be acceptible for mesa
and pushed in git - i don't know better :).
