That's a nice idea and would also benefit programmatic uses of
g_object_bind_property(). These functions would have to be in GLib,
though; otherwise, using them would require an external library where
they are defined in.

GBinding already defaults to using default transformation functions.

Really? This isn't documented anywhere. Thanks for mentioning! I admit
that this makes the need for transformation functions much less
pressing, but they are still a very useful feature.

Yeah, the best documentation I find is, when calling the _bind_full() function
and passing a NULL transform function "the default will be used" ;-)

In gbinding.c its quite clear... the default is to try g_value_copy() first and
then resort to g_value_transform().
