Fix a warning)
i have broken tri-viewport in non-composited case, so nearly all OpenGL demos
are broken. If i enable compositing in e16 config menus - tri-viewport show
correct, full image in it's window. It was like this for some time, i'm sure
latest mesa commits not responsible for this breakage, but i don't remember
correct mesa/xserver combo. At least around

Revert "r200: make use of DMA buffers for Elts a lot better."
it was working ... but i see no point in bisecting this - since this there
was new libdrm interface, fixed xserver dri2 interface .. everyone want new
code fixed, no? Probably, i just need to add few printfs inside
r200UpdateWindow, or it's callers? Or something like this into xserver dri2
code (just for seeing waht values were send by X server to driver and down to
stack)
