[Bf-committers] glFlush glFinish, ATI testing

I'm still seeing *very very* slow menu drawing (WinXP pro, Radeon 7000, 
Pentium IV). My experiments in this area got a major increase in menu-drawing 
speed by drawing to the back-buffer and swapping rather than drawing to the 
front buffer; unfortunately my hacky coarse-grain buffer-swap caused 
horrendous problems in vertex-paint mode...

... I believe that the slow-menu-draw is related to drawing text, since 
the 'rendering progress' text is also extremely slow - as is 'B-select'...

I haven't had any time to progress my experiments in this area unfortunately :(

> Just committed by Kester... replacing the glFinish call with glFlush

> Please update and compile, and if possible post a test binary on the  
> testing builds forum!
> If this works out well, we can close one nasty series of reports. :)
