I must admit I need to go back to check the reference books and the
code to answer accurately.

However, many things cause events to be generated in X, which can
simply be picked up by the main event loop and handled.  The Carbon
active scroll bars use callback functions to perform the scrolling.
It's not so easy to adapt this model (Carbon) to one with an event
loop that expect to receive active scrolling events (Emacs).

Some events are even absent.  Right now the Mac code detects mouse
movement by polling.  There has to be a better way to this.

These are the kind of improvements to the event handling code that I
am thinking about.
