Yes it does.  I guess I didn't quite explain it right :)  In your 
example, the minimum required width of the widget increases as the 
height changes.  The widget could have more width allocated to it, but 
you want the minimum width to be dependent on the height.

As an example, consider a container like you described holding twelve 
equal sized children.  If you size the container such that it can fit 3 
rows of children, then you want the minimum width to be enough to fit 4 
children across.  We want to allow the user to reduce the height of the 
container (to give a 2x6 or 1x12 configuration), so we can't use 3 rows 
as the minimum height request -- it should be one row.

Similarly, we want to be able to make the container less wide if the 
container grows in height so the minimum width request can't be 4 -- it 
should be one column for the 12x1 configuration.

However we don't want GTK to resize the container to one row by one 
column, which it currently could if the minimum size request was 1 row 
by 1 column.  This is why the geometry handling would need some changes 
to correctly handle the type of container you proposed.
