gtk interfaces status

[Jerry DeLisle]

I noticed that folks on c.l.f did not take much interest in this. I suppose 
because people who need high performance graphics are already using various 
available tools.

I see this as a nitch tool and its use will grow as people learn how easy it is 
to use.  There is a learning curve of course.

Vincent now has a Python script that is taking the gtk+ .h files and generating 
the Fortran interfaces.  The function count is now up above 4000 functions and 
gives pretty much complete access to all of gtk+ and then some.  It has not been 
committed to the repository yet, but will soon.

Hats off to Vincent Magnin for doing this. I really think we need to consider 
adding an intrinsic module to gfortran (4.7) for this stuff. We also found a bug 
related to the correct interface to g_signal_connect_data which has been fixed 
in the repository. (Thanks to a new user who figured that out)

Cheers,

Jerry
