This call returns the current frame count of the swap group.

Function	B00L QueryFrameCountNV (HDC hDC, GLuint
	*carrier);

Parameters In	hDC - Device context for the frame lock card, or a
	window residing on the frame lock card.

Parameters Out	*count - The current frame count of the swap group.

Return Values	TRUE: Frame count successfully retrieved.
	FALSE: Frame count retrieved failed.
