Fixes 9cb646bbd2 for the case that a frame or dialog is shown,
then hidden, then a new canvas is created or a new compatible
bitmap is requested via the `make-bitmap` method.
The test for this change is just the "windowing.rktl" test, which I
forgot to run before (as opposed to the drawing test suite).
(cherry picked from commit d234c0c2e3)
The backing bitmap for a canvas is created as a CGLayer, which can
make screen refresh much faster. Also, calling the `make-bitmap` method
of `canvas%` produces a CGLayer-based bitmap, so drawing those bitmaps
to a fast context can be fast.
The improvement particularly helps with Retina displays, making
DrRacket more responsive and increasing the potential frame rate
of Slideshow.

- edits to the docs
- adjust the #:i-th argument interpretation to allow
any natural number (using modulo for finite enumerations)
- remove unnecessary gui dependency of a few test files

The `setup/xref` library conceptually belongs in "racket-index",
and moving the library avoids a cross-package use of a private
module.

Avoids a gray box at the bottom of the GRacket REPL window on
startup, or in DrRacket when a horizontal scroll is automatically
removed due to, say, hiding a interactions window positioned to
the right of the definitions window (where the definitions content
is narrower than the whole window but wider than half).

Make executables created by `raco exe` not refer to the original
configuration directory by default, but add an option for setting
the directory.
For Unix ELF executables, fix `raco exe` to set/preserve the
configuration directory.

When the "racket-index" package is in user scope, then the

A direct reference makes the "gui" package depend on the
"drracket" package, and making the reference indirect avoids
that dependency.

Two of the contracts were inaccurate and, if true, would
