  Bug fix #2296
   - Background image would jitter around on ATI card when zoomed in too
     far. It appears that the driver is was multiplying the image width
     by the zoom factor at some point and clamping this number, before
     clipping the visible image. Somehow this then fed back in to clipping
     the zoom factor.
  
     Fix is to only tell GL to draw the smallest number of pixels (width
     and height) that would be visible on the screen. Since this is not
     a generally bad thing to do applied fix for all users of
     glaDrawPixelsSafe.
