* glib/SignalClosure.cs: post back the gvalues after the closure is invoked using a new Update method on GLib.Value. This only impacts boxed types, since they are the only "value types" passed by ref in the signal marshaling environment. We can't call set_boxed on the value to update it, since that allocs new memory, we need to marshal the updated struct out to the existing native memory address using g_value_get_boxed. * glib/Value.cs (Update): new update method for writing values to an existing boxed type instance instead of allocating a new native struct. Fixes #398929. svn path=/trunk/gtk-sharp/; revision=106058
