I was just wondering, why are Windows and Buttons
derived from Gtk2::Bin instead of Gtk2::Box?
Does it make them more efficient?
I don't claim to have insight into the minds of the gtk+ authors, but
my guess is that it's because Windows and Buttons conceptually just
have one child. That child may be a box that has more children, but
that box is a single child. It wouldn't make sense to have Window or
Button descend from Box, because Box is a base that must be
subclassed with a direction --- how wasteful to require the existence
of HButton & VButton, or HWindow and VWindow.
