Hrm. I misunderstood the purpose of {window->State.Width} and

Browse Source 
{...Height}.  Those are *not* records of the old values, but rather
of the *desired* *new* values, hence it was inappropriate to use them
in ConfigureNotify X11 event handling.  Doing so introduced some new
problems.

So, I created OldHeight and OldWidth in the window State structure,
and *those* do what I require.

I also stripped out the obsolete comment about getting extra/bogus
reshape events.  (Though I maintain that an application should be
robust against them, freeglut should no longer generate them if the
window has not changed size since last reported.)
