Tristan Van Berkom 9d0c2f6b37 Make GtkCellAreaBox handle rendering without a previous allocation in the orientation of choice.
This is so that treeviews can have some columns oriented vertically and
some horizontally, usually the column will only allocate the areas
width, having vertical columns without fixed row heights just means
it's slower to render.
