missing g_signal macros

[Sven Neumann <sven gimp org>]

Hi,

we started to port Gimp to the GLib/GTK+-2.0 API and I found myself
using the generic (and lenghty) g_signal funcs very often. I'd vote 
for including the following convenience macros:

 g_signal_connect_after()
 
 g_signal_handlers_disconnect_by_data()

 g_signal_handlers_block_by_data()
 g_signal_handlers_unblock_by_data()

If this is OK for you, I can provide the necessary simple patch.


Salut, Sven
