Commit, mostly of work from John:

Browse Source 
* Removed some say-nothing-useful comments.
 * Added some tentative mouse-wheel support.
 * Fairly massive reformatting of code.

I made some secondary changes to his changes:

 * One compilation error was fixed (missing close-paren + semicolon).
 * Deleted a few ore say-nothing-useful comments.
 * Some of John's code was strangely formatted to the point that it
   seemed completely out of place, so I took the liberty of reformatting
   it.  Since I used GNU EMACS's <tab> key (which re-indents rather than
   inserts TAB characters), I had to propogate some indentation changes
   a little further than the bare necessity to match up with John's
   changes.  (John seems to shoot for 2-space indents, while EMACS
   (and I, I confess) strongly prefer 4-space indents.  The code that
   I was re-indenting had been put to 8-space indents, however.)

I have *not* tested the code beyond compiling.  I assume that John did
(and that the compilation error was a result a minor change just before
asking me to commit).
