I've spent about 20 minutes trying to figure out how to distinguish
between a "mouse wheel up" and "mouse wheel down" event! I'm receiving
the SWT.MouseWheel event, but the resulting Event object doesn't seem to
depend on the direction the wheel was turned. Any clues from the higher
powers?

Use the count field on the event, it's possitve for up and negative for down
