All changes are from John, except for:

Browse Source 
(a) I re-inserted the meat of a comment that I still feel is relavent.
 (b) I fixed a compile-time error in the UNIX_X11 code where a variable
     is declared after executable code in a block without creating
     a new sub-block for the declaration.

Changes from John include:
 (a) Style revision.
 (b) Changes to postpone the handling of window resizes.

Lots of lines were changed, but I think that thos two cover the ground that
he hit.  See the diffs for details.
