[Bf-committers] Instructions on use of patch

[joeedh]

oh man, I just realized I left in the debug thing where the selection 
backbuffer is swapped to the front every once in a while!  I did it so I 
could examine it to fix some problems (which I did managed to fix 
completely).  Had to modify the glClearColor first, but luckily I did 
change that back to normal.

So: to fix, find "force_backbufdraw_ext" in 
source/blender/src/drawview.c, and uncomment the line "curarea->win_swap 
&= ~WIN_BACK_OK;", at line #935.  It's not that big of a deal really, 
but having the screen draw the selection backbuffer every once in a 
while is slightly annoying.
