X uses the display DPI as calculated from the monitor dimensions and
resolution.  Most toolkits should make this pretty transparent,
unfortunately some desktop UI's seem to have "standardised" on 96dpi and
fail to ensure their dialogs, pop-ups etc scale correctly.  The key here
is to not use pixel units...

...which of course makes image scaling much easier! :)
