After this commit, pc files no longer include the gdk backend in
their name, and we no longer install a pc file for gdk. There is
now a single gtk+-3.0.pc file. It turns out a separate gtk+-x11-3.0.pc
file is not necessary, since gdkx.h doesn't have a separate include
directory that would have to be added to Cflags.
In particular, rename
- libraries to lib*-3.0.so
- pc files to *-3.0.pc
- include paths to /usr/include/gtk-3.0/*
- module paths to /usr/lib/gtk-3.0/*
- rc files names to gtk-3.0/gtkrc
- commandline utilities to *-3.0
- adjust documentation
Also change the install location for unix-print headers to
/usr/include/gtk-3.0/unix-print/gtk.
