-------------------------------+------------------------------------
Qt's swapinterval method which used glXWaitVideoSyncSGI and
glXGetVideoSyncSGI is not suitable for warzone.
See: http://dri.freedesktop.org/wiki/CompositeSwap
!'' Depending on the application, it may be appropriate to throttle your
rendering to a factor of the refresh rate (using SGI_swap_control or
OML_sync_control) if you can't keep up with it; this avoids a variable
frame rate which can be visually distracting.
!''
I've attached a hack that uses SGI_swap_control instead.
Note: It doesn't actually check the setting because of the organization of
the header ( indirectly including X11 anywhere causes major pollution,
this especially doesn't mix well with qt).
