Details:

The three container UI objects figure, uibuttongroup, and uipanel have a
"sizechangedfcn" property which holds a handle to a callback function.  The
property has been implemented for figure objects (see graphics.cc), but not
for uibuttongroup and uipanel.

I don't believe it would be particularly hard to add a set_position function
for the other two objects which would update the position when changed, and
then check for a callback function to execute.  As I noted, there is already
example code that could be taken from figure::properties::set_position.
