Don't queue resize for hidden widgets without a size group

queue_resize basically tells the parent widget that it may need
to pick a different size/layout. However, for a hidden child widget
that should never be needed. It may be that the widget is in a
sizegroup that has ignore_hidden == FALSE though, so it may
affect the size group calculations.

However, if a widget is not visible and not in a size group then
its safe to avoid the resize, as the widget will be resized on
becoming visible anyway.

This avoids a lot of size allocation for hidden things like menus
and tooltips.
