September 10 - FOX DEVELOPMENT 1.7.84
(Redrop of this version due to file missing from manifest).
New FXUndoList implementation. The new FXUndoList now supports an alternate history mode, i.e. it remembers redo-command
after taking a different path. The internals of FXCommand have changed a bit, it now sports a reference count; for the most part
that does not affect any user-code.
Also in FXUndoList: on 64-bit machines, space-accounting is now performed in long to manage potentially
large amounts of undo data.
Adie editor undo sytem now supports merging undo commands, if the text is changed letter-by-letter it will
consolidate contiguous commands, assuming they are considered mergeable. Currently we're keying on character classes
to decide whether to merge or not. Idea is to not back up over programming-language special characters.
Inlined some math functions for greater speed.
Inlined some character-class APIs in fxascii for greater spead.
FXSystem::system()
