Bug#365602: Patch for changing font size in a fixed-size window

Hi,

I think this is more than just a minor bug, as it very much reduces
the usefulness of font size changes.  In return for inflating the
severity, I offer a patch :)

With this applied, you can maximize an xterm, fire up a program like
emacs, hit "shift-KP_PLUS" and "shift-KP_MINUS", and marvel at how the
program resizes with the font to fit the screen.
