Log:

OpenGL Vsync: Use the NV Control extension to test for OpenGL VSync.

This will perform a couple of checks to determine whether OpenGL Sync to
VBlank is enabled at run time and offer (via the log) some ways of
enabling it if not.

This is currently for NVidia linux only - I'll add other checks where
available.

N.B. The proprietary NVidia driver will never sync to vblank unless
enabled before the app has started. Forcing the swap interval and other
methods will have no effect.

Modified:
