NAME
       ggiGetRayPos : Find out where the raster beam is

SYNOPSIS
       #include <ggi/misc.h>

       int ggiGetRayPos(ggi_visual_t vis, int32_t* x, int32_t* y);

DESCRIPTION
       Though  currently  only	implemented  via  matroxfb, this function will
       retrieve the current position of the raster beam on a display that uses
       a  cathode  ray tube, or resembles such internally.  Because it has not
       been implemented and put into widespread use, there may be API fluctua‐
       tion as to exactly what units x, y are in, especially on displays using
       doublescanning modes.  In addition to numerical values,	the  following
       values  can  be	returned  in either dimension: GGI_RP_BORDER means the
       raster is in the border of the screen; GGI_RP_BLANK means the raster is
       past  the  border  and  is  turned off; GGI_RP_SYNC means the raster is
       retracing to the top of the screen.

RETURN VALUE
       0 for OK, otherwise an ggi-error(3) code.
