Add a window geometry tip when users move/resize a window. Currently it is

enabled by default, but will be made configurable soon. There is a known
issue with an incorrect geometry shown with konsole, but that's its fault,
and I'll get to that shortly (xterm does the right thing).

Disclaimer:
If it jams - force it. If it breaks, it probably needed replacing anyway.
