Cocoa: use ellipses instead of line wrapping
Gtk: allow column sizing below title width
Merge to v5.3.4
original commit: 33700427f26b14704dc4e4f315e36b6cc597e219
A scroll request could fail if a resize notification is still
in flight (i.e., queued but not yet executed), so double-check
the size on a scroll request.
Closes PR 13582
original commit: bfc9c41358face5c6d79bad591b842e7f5dc38e8
It's possible to go from a state where one scroll bar is needed
(vertical or horizontal) to a state where each scrollbar is
needed iff the other scrollbar is needed. In that case, the
auto-scrollbar algorithm couldn't find either fixpoint and
would loop forever.

Removed the method from `canvas<%>', where it was never implemented
with the `racket/gui' reimplementation.

to let lexers say "call me again before you change the buffer"
also, use this in the 2d lexer

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)
original commit: b0343aa9f02f0024cba7a61db3bcf4165696dd85
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
original commit: ca8ad3b88b38034e4dac6715511a749581d0c059
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)

Unclear if this is a bug in get-active-canvas or not

This time with test cases, and also without changing the
semantics of unhighlight-range

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)

In other words, go back to (a rackety version of) the old
