Use glFlush() if swapBehavior is single-buffered
Otherwise, use swapBuffers()
This fixes an issue where swapbuffers() did not swap the
"back buffer" to the "front buffer" if we had single-buffered swap
behavior.
This was an issue on Windows 7 with an NVIDIA graphics card that
by default was using single-buffered mode.
