/* Hack to work around a nvidia windows driver bug. The clear below is supposed to
* clear the red quad in the top left part of the render target. For some reason it
* doesn't work if the clear color is 0xffffffff on some versions of the Nvidia Windows
* driver(tested on 8.17.12.5896, Win7). A clear with a different color works around
* this bug and fixes the clear with the white color. Even 0xfeffffff works, but let's
* pick some obvious value
