       gl_setcontextvga - set the context to the physical screen

       #include <vgagl.h>

       int gl_setcontextvga(int mode);

       Set  the  graphics context to the physical screen of a vga
       mode (as defined in vga_setmode(3)).  The mode must be set
       with  vga_setmode(3)  prior  to  using  any of the drawing
       functions.  vgagl does not take care of that.

       The function returns 0 for success  and  non-zero  if  the
       mode is not supported by the hardware.

       The  only thing you can do with a planar (mode X-like) 256
       color mode is aligned gl_putbox, and use it  as  a  target
       for gl_copyscreen.

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