	I downloaded your version of libAfterImage, compiled and installed
	it, and tried with my "standard" root installation (binary
	version	from root_v3.03.09.Linux.RH7.2.gcc296.tar.gz). And now,
	it works !!! Thanks ! No need to compile root myself !

	Here are the signature for create_asvisual_for_id :

	-> In the first version I used :

	(asvisual.h)
	ASVisual *create_asvisual_for_id(Display *dpy, int screen, 
	                                 int default_depth, VisualID visual_id,
	                                 ASVisual *reusable_memory);

	-> In the CERN version :

	(asvisual.h)
	ASVisual *create_asvisual_for_id(Display *dpy, int screen, 
                                         int default_depth, VisualID visual_id, 
	                                 Colormap cmap, ASVisual *reusable_memory);


	One thing is very strange for me : the two different versions
	of libAfterImage (the one I downloaded on sourceforge and the CERN
	one) are different, but are both labeled "0.92"...
	(libAfterImage.so.0.92 in $PREFIX/lib).

	Cordialement,

	Laurent
