This function is only for use in widget implementations. Obtains
widget->requisition, unless someone has forced a particular
geometry on the widget (e.g. with gtk.widget.Widget.setSizeRequest),
in which case it returns that geometry instead of the widget's
requisition.
This function differs from gtk.widget.Widget.sizeRequest in that
it retrieves the last size request value from widget->requisition,
while gtk.widget.Widget.sizeRequest actually calls the "size_request" method
on widget to compute the size request and fill in widget->requisition,
and only then returns widget->requisition.
Because this function does not call the “size_request” method, it
can only be used when you know that widget->requisition is
up-to-date, that is, gtk.widget.Widget.sizeRequest has been called
since the last time a resize was queued. In general, only container
implementations have this information; applications should use
gtk.widget.Widget.sizeRequest.
