Is anybody out there using the XGL Graphics Library from Sun?

I am using a SparcStation2 with a CG6 accelerated 8bit display. In
order to synchronize the display of image sequences with the refresh
of the screen I need to have a routine that tells me about the 
vertical retrace period. Supposely the XGL Library has a flag called
'XGL_CTX_NEW_FRAME_VRETRACE' used by the routine 'XGL_CTX_NEW_FRAME_ACTION'. 

Does anybody know how this is implemented?
Do I need a new display driver for that feature?
