When the terminal is resized the programs running in it receive a Unix
signal (SIGWINCH?). By default that signal is ignored. However, one can
install a signal handler for it and then presumably call into the system
(some terminal API) to ask for the new sizes.
I could probably figure out how to do this in C, but I'm not familiar with
how Ada on Unix deals with Unix signals.
