* xsettings-client.[ch]: Add xsettings_client_set_grab_func(), xsettings_client_set_ungrab_func() to allow users to control exactly how server grabs are done. (In case the user has a refcounted grab facility, for instance.) (Patch by Soeren Sandmann) * xsettings-client.c: Use XInternAtoms() to reduce roundtrips. * xsettings-client.c: Fix a memory leak for XGetWindowProperty() on type mismatch.
