A long time ago, I tried to improve the interactiveness
of DrRacket when the contour window was open with the
code that is removed in this commit. Looking at it today,
it seems clear that this code was buggy (and, now that
we've had lots of experience with it, it didn't actually
help with interactivity either)
The problem is that the code didn't record enough
information about the change to the editor in the thunk put
into the 'todo' field. It would remember that a particular
range was out of date, but it woudln't remember which
characters were in that range, so when it would go to copy
the characters, it may be getting the wrong characters
(since another edit may have happened since the thunk was
stored in the todo field)
This change also has the side benefit that the time it takes
to change the contour window is now being tracked by the
colorer, which means that it'll give up a bit sooner
coloring less in each go, but hopefully maintaining the
interactivity
in the original GitHub fork:

Some things about this are known to be broken (most egregious is that the
array tests DO NOT RUN because of a problem in typed/rackunit), about half
has no coverage in the tests, and half has no documentation. Fixes and
docs are coming. This is committed now to allow others to find errors and
inconsistency in the things that appear to be working, and to give the
author a (rather incomplete) sense of closure.
inside the same collection so this file can (when other
things aren't too different) be used in a version of racket
that doesn't generally have the tests
Track fixnum results in the same way as flonum results to enable
unboxing, if that turns out to be useful. The intent of the change,
though, is to support other types in the future, such as "extnums".
The output `raco decompile' no longer includes `#%in', `#%flonum',
etc., annotations, which are mostly obvious and difficult to
keep in sync with the implementation. A local-binding name now
reflects a known type, however.
The change includes a bug repair for he bytecode compiler that
is independent of the generalization (i.e., the new test case
triggered the old problem using flonums).
