(Just to add my 2 bits to Tero's answer on this)

Yes, this is necessary. Basically, gtk-- widgets have their own gtk
type. So, we can't call the gtk_*_new() functions, because they all
call gtk_type_new() with the "wrong type" (the original gtk one, which
we don't want).

Therefore, any initialization which is done in a gtk_*_new() has to be
duplicated. Or, as was done with GtkCList and GtkScrolledWindow, we
put all object init stuff in that seperate _construct() function.

So, it boils down to having _new() functions which would only call
gtk_type_new() and gtk_*_construct().
