Seems to work for Mac OS X 10.9 (Mavericks), at least.
In Retina mode, a drawing unit corresponds to two pixels on
the screen or in a bitmap created by `make-screen-bitmap'.
In particular, a bitmap created by `make-screen-bitmap' is
actually twice as big in each dimension as requested, and the
bitmap is scaled when transferring to other drawing contexts.
When transferring onto the screen, scalings cancel so that the
result looks right.
Adds `get-display-backing-scale` to `racket/gui/base`, and
also `get-backing-scale` to `bitmap%`.
To do: add a way to set the backing scale of a bitmap. That
option will provide a way to give controls higher-resolution
bitmaps as labels.

When files passed to the default application-file handler cannot be delivered
because no frame is active or the frame does not accept files, then retry
when the active frame changes in the future (in addition to when the
application-file handler itself is changed).
This adjustment should fix a long-standing problem where files are
not delivered to DrRacket on Mac OS X.

it now checks to avoid drawing the line numbers when
the invalid region is not lined up in the X direction

- shorten the example text
- fix a bug that would prevent info-based color schemes
to be set properly when drracket first starts up
- make the preferences dialog examples use the user's
preferred font, not the default font
- move the documentation and info buttons to the top
of color scheme section of the prefs dialog
- added a checkbox to go back to the default version
of the color scheme

- better overview docs (now in the drracket manual)
- something inside the drracket gui to get the list of the
available style names and to send you to the new docs

the rearrangement moves the string constants documentation
into a package over by the string-constants implementation
and adds the string-constants (meta) pkg.

This reverts commit 3c439a773138ca86a3810de6a37912ff588f7d0e.
Instead of changing the default colors, add support for color
schemes and then use these colors as a starting point for a new
color scheme

Also, a bit of Rackety (triggered because I would have had to turn a
letrec into a letrec-values to support disabling the ok button (and
also because the code was indented with tabs and not just spaces))

it no longer changes the background to the inverse of the
foreground (for the default text color) but instead uses
the color of the 'framework:basic-canvas-background preference
Thanks to Laurent Orseau for the fix

Also, move remaining "srfi" libraries to "srfi-lite-lib".
In principle, "base" should depend on "scheme-lib" and
"srfi-lite-lib", and a new "base2" package would represent the new,
smaller base. But I don't think the window has yet closed on
determining the initial "base" package.
The "srfi" libraries moved to "srfi-lite-lib", instead of "srfi-lib",
to avoid creating many extra dependencies on "srfi-lib" and all of its
dependencies. The SRFIs in "srfi-lite-lib" depend only on "base",
and they are used relatively widely.

fix a bug in 27603faf, I believe

- paren color from brown to a neon blue
- string and number constants from green to a bright purple
- lighten the comment color
the basic problem is to try to keep the red error color very distinct
from the others and try to keep the others distinct from each other
(but that's less important)

In a container sequence, hides and shows are delayed, but
reparenting needs the hide operation to really complete.

Extra margins added by instantiating `message%' inside
`radio-box%', etc., made labels line up especially badly.

the actual values
so changes to the default imply changes to everyone's actual
values for the prefs
