       gl_setcontextvirtual - define a virtual context


       #include <vgagl.h>

       void  gl_setcontextvirtual(int  w,  int  h,  int  bpp, int bitspp, void


       Define the current graphics context to have a width of w pixels, height
       h, bpp bytes per pixel, bitspp significant color bits per pixel (8, 15,
       16 or 24), with the framebuffer at vbuf.  A 4 bytes per pixel  context,
       with 24 significant color bits is also valid.

       original documentation is unknown.

       It is very likely that both are at least to some extent are due to Harm

       Occasionally  this  might be wrong. I hereby asked to be excused by the
