GSdx OGL: renders upside-down image to a tiny area on the upper-right corner

[GoogleCodeExporter]

GSdx OGL renders upside-down image to a tiny area on the upper-right corner 
(see attached picture). Both in game (tested with FF X) and in PS2 boot menus. 
Both in windowed mode and full screen. Tested with GL Hardware output, GL 
software and SDL software. (GL Hardware also renders corrupted picture, but at 
the moment this is irrilevant).
