Wheel handling in cocoa.m and in monitor.c may supply a delta greater
than 1 for the mouse wheels. Those front-ends would have to translate
those deltas into a series of press+release events. Then the emulated
devices (at least the PS/2 and USB devices) would have to sum the
designated button presses for outputting again as wheel data.

If that's the way we want to go, I can rework the patch easily enough.
