lexers it defers to
also, remove the checks in color.rkt in the framework (they are not
all covered by the added contract, but they mostly are and when they
aren't, most of those times are using the heavily tested racket-lexer)

The method uses the new `impersonator-ephemeron' function to
retain a callback as long any value that it impersonates
is reachable.

in the line numbers when it moves around
specifically, if the before and after green line are right
next to each other, then put it into a single edit sequence
(which unions the invalidated regions); if not, then we
may be jumping far away, so invalidate the two regions
and redraw them separately

Also, some cleanups of the code and
make the syntax-color/ library docs
point to color:text<%> instead of
color:text% (as the interesting information
is attached to the interface, not the class)

Specifically when there is no delegate and an edit
sequence is started, track that differently in case
a delegate is set before the edit sequence ends
(in which case we don't want to end the edit
sequence in the delegate since we didn't start it
there)

edit the buffer" attempt
In other words, go back to (a rackety version of) the old
implementation of the get-close-paren method
original commit: ab55d43312a0b5c430db12096bf659f54d26ef8b
They hypothesis behind this change is that the undo is
undoing an edit that came before, not the temporary edit
that appears in insert-close-paren. So, when there are
no edits happening (ie when fixup? is #f) then don't
undo. This is only a hypothesis because we were not able
to find a small code sequence, outside of DrRacket to
cause the bad behavior, so possibly there is really more
going on here.
Thanks to Nadeem Abdul Hamid for finding this fix.

The code to draw a border has to determine the widget's position
within the drawing window. Gtk 3.0 has a function to provide that
transformation, but Gtk 2.0 doesn't seem to have one, and it seems
that the transformation implemented in `racket/gui' wasn't right.

The goal is to better handle situations like this one:

╚═══╝
where the hyphen should not change.
