[Gtk-sharp-list] Serialization Compliance Problems

The problem with this, is that there are some ctors that won't function
properly, as certain properties are only settable when the ctor is done.

Forexample, setting the WindowType in a new Gtk.Window is only possible
when you create it, so a default () ctor would not allow this to be
used.

There are other examples of this, where there are ctors that allow you
to modify things that are not changeable later in the objects lifecycle.

This is a gtk+ issue, that we are basically unable to workaround.

How would MyXAML handle cases such as this?
