That's fine - that's clearly a broken widget, or at least one which knows
that it is dealing with broken widgets and must change when they are fixed.

Actually I have a number of thoughts about Geometry management in general.
Andy Schulert and I are doing a paper for Xhibition which will talk about
them and which expresses what we think the Motif widgets should do once they
are consistent.

Specifically on that question though, I think I would prefer Done instead of
Yes.  It puts a little more burden on the managers (but not much) and makes
life easier for the primitives.  It also seems like it's easier to change a
widget to that policy than the other, which is good for integrating non-Motif
widgets.  Why might Yes be preferred?

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
