The expose event works because the parent widget has it in it's event
mask by default, and container widgets are responsible for propagating
expose_event signals. (But nothing else)

Maybe there should be a warning when gtk_widget_set_events is called
on a GTK_NO_WINDOW widget ... it is always a mistake.

Something like the following - what do people think? (Untested patch
warning!) Of course, it still wouldn't be transparent why the warning
was happening. But a FAQ entry could fix that.
