I've occasionally wanted to create tiny windows
(for example I originally made bargraph less tall)
and it's a little annoying that rio's requirements for
text windows applies to windows that won't be
managed by rio.

The right solution is to fix libframe to gracefully handle
the case where the window has no room for text.

It's nice that rio shrinks the subwindows when you
resize.  It just needs to be able to handle the consequences.
