Subtle differences can make porting difficult.  For example, it will
take a bit more work to make scroll-bars behave like standard (Mac)
ones.  Currently, scrolling will not `auto-repeat' if one clicks and
holds down the mouse in the up or down arrow area.

At some point (in transition to the Mac OS X code) I had a Carbonized
verison that will run on Classic (with CarbonLib, of course).  Right
now the Mac OS X code contains a lot of ifdef's.  Perhaps if it is
worth the effort, at some point we can move towards a unified
Carbonized version.

Oh, I was thinking about how to get Emacs to do interrupt-driven input
via signals.  Specifically I was thinking about how to `connect'
keyboard and mouse events to (Unix) signal handling in Emacs.
