Hello. For my game (http://freetennis.sf.net), many people are
complaining about compilation errors. They install lablgtk2, lablgl,
camlimages and ocamlsdl, but their compilation fails at the line:

       Gpointer.blit ~src ~dst:(GlGtk.region_of_raw raw);

Their compiler says it does not know the module GlGtk.

The reason (I presume) is that their distros compiled lablgtk2 with
--without-gl (right?).

The reason (again I presume) is that gtkglarea-1.99 is not mantained anymore.

Therefore I must make it easier for users to compile my game. I assume
I need to change my code so as not to use the module GlGtk.

My question is: how can I do without GlGtk? Fortunately I am _not_
using GlGtk.area. I am only using GlGtk.region_of_raw. What would you
do to avoid its usage? The code is the following:

 let glPixOfPixBuf ~pixbuf ~makeSquare64x64 =

       let src = GdkPixbuf.get_pixels pixbuf in
       let raw = Raw.create `ubyte ~len:(Gpointer.length src) in
       Gpointer.blit ~src ~dst:(GlGtk.region_of_raw raw);
       GlPix.of_raw raw ~format:`rgba ~width:(GdkPixbuf.get_width pixbuf)
           ~height:(GdkPixbuf.get_height pixbuf)

Thanks for any help,

Maurizio
