From Marius Heise, "here is a patch that implements Win32 HW-synced swapping using wglJoinSwapGroupNV, wglBindSwapBarrierNV and the existing traits. It was tested with multiple ATI FirePro S400 cards.

I also fixed the vsync implementation introduced with rev.11357 that was crashing with the Windows Error #170. So I removed your temporary /* */ around the vsync condition..."
