       gl_setcontextvirtual - define a virtual context


       #include <vgagl.h>

       void gl_setcontextvirtual(int w, int h, int bpp, int bitspp, void *vbuf);


       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.
