Andrew,
I have committed another revision of the aspect-ratio handling. It seems to
work pretty well, and I think pan/zoom work in a reasonable fashion now. Many
times in the past, however, I have thought that aspect-ratio handling was
working adequately, and every time someone has found a major bug. This time is
probably no exception.
There can be some anomalies when the window is resized quickly--that is,
grabbing a window corner and slinging it around with axis('equal') can cause
some incorrect choices of the view limits. I haven't figured out why.
Although I certainly would like to understand and fix it, it is not a top
priority at the moment because I don't think it is a major problem in practice.
Eric
