A pan gesture is turned into a WM_{H.V}SCROLL event in a
way that `racket/gui` did not recognize as a change to the
scrollbar. I'm not sure that this change fixes the problem,
but it seems worth a try.

For a font with 'aligned hinting, the font map caches metric
information that depends on the destination transformation,
at least on Windows. Make the font-map cache sensitive to the
destination's current transformation.
This bug was exposed by support for DPI-aware GUIs on Windows,
but the problem was more general.

Roundoff can place a child of a container so that it's position plus
width extend beyond the container's width. For some controls, that
looks especially bad. Approximate precise scaling by having those
control sizes round down, instead of up, while leaving other kinds
of controls alone.

The `racket/draw` library is now independent of the screen resolution
on Windows. Font sizes in "points" are the only place where the
resolution mattered before, and now `racket/draw` assumes a
traditional 96dpi on Windows and Linux (and a traditional 72dpi
on Mac OS X).
Setting the scale for "text and other items" in Windows now adjusts
the backing scale of screen and canvas-compatible bitmaps, as well as
setting a scale on canvas drawing. Window and screen positions and
sizes are similarly scaled; for example, if the screen is 2048x1436
with text scaled by 200%, then `racket/gui` reports the display size
as 1024x768 (and the display backing scale as 2.0).
Backing scales of 1.25 and 1.5 are common for Windows. Rounding
associated with those scales could cause trouble for virtual -> actual
-> virtual conversions.

If a keymap has a grab, then discard key events that are modifier
changes or key releases.
Adjusts commit 8ba8d01ec0 so that Ctl-u work in DrRackt (and
other framework-based programs).

Suppress WM_KEYDOWN messages to a button or checkbox, so that the
top-level window takes care of Space and Return for a button or
checkbox with the keyboard focus.

Previously, `keymap%` would return #t for all shift, ctrl, and key release
events. DrRacket's editors would then not handle those events (correctly,
as they shouldn't handle already-handled events), meaning that the events
weren't sent to any snips.

The `panel%` and `pane%` classes were not originally intended for
direct instantiation; instead, `horizontal-pane[l]%` and
`vertical-pane[l]%` provide basic placements that make sense for
multiple children. Adjusting `pane[l]%` to just overlay all children
seems both sensible and useful (if only one child is shown at a time,
for example).
As suggested by David Nelson.

The changes to `pen%` and `brush%` are related to the
`racket/class` repair of the previous commit, while the
`style%` change is because I didn't look at it before.

Also, fix the docs to clarify that `just-alpha?` as #t means a no-op for

This change requires a coordinated change to the snip-lib pkg and to
the gui-lib package. The docs are in the gui-doc pkg and yet point to
the snip-pkg as the containing pkg, so I updated the version number
for snip-lib and left the version number for gui-lib alone

Modules are not supposed to move to different packages, anymore, so
I'm breaking a rule. The problem is that having `rackunit/docs-complete`
in "scribble-lib" made "scribble-lib" depend on "racket-index", and
that's an undesirable dependency. (Installing Scribble shouldn't
force you to have Racket documentation.) I should have noticed
the problem when I moved `setup/xref` to "racket-index", but I missed
it.
As far as I can tell, there's only one package on pkgs.racket-lang.org
that isn't in the main repository and uses `rackunit/docs-index`. The
package doesn't correctly declare its dependencies, anyway.

In the case that the flush queue was empty, the first byte that
comes it would appear to have come from a long time ago and
thus get flushed immediately.
Instead, when the first byte comes in, we restart the timer at that
point, intead of holding the old value

Before this commit, autosave files would (incorrectly) contribute to
the file's last modification time in a way that meant that after an autosave,
the warning would start triggering when the file is saved normally

This one of those classic n^2-loop-that-should-be-linear bug. The fix
speeds up this program (when run in DrRacket) by about 1.75x:
(for ([x (in-range 10000)])
(display "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz\n"))
The bug is fairly old too: I introduced this bug on March 6th,
2004. (Thanks, Sam, for making that old history accessible!)
