NAME

       gl_setcontextvirtual - define a virtual context

SYNOPSIS

       #include <vgagl.h>

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

DESCRIPTION

       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
