Register a button as a default button every time that it is shown,
so that multiple buttons in a frame can have the 'border style
(as long as only one is shown at a time).

On Cocoa, a view's `drawRect:' method can be called from a
heartbeat thread that animates controls. Such a call happens
rarely for a `canvas%' or other class where `drawRect:'
is overridden, but since it can happen, ensure that the
callback runs on the Racket thread.

There were especially problems with header columns, but
also intercell spacing was not taken into account.

The relevant `on-paint' call is one that is forced for a GL
canvas to try to draw a frame's content before the frame is
shown. Sometimes, thread scheduling would let the frame get
sufficiently initialized at the Cocoa level before the `on-paint'
call happened, but sometimes not.

Gtk: allow column sizing below title width

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.

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.

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)
