Two of the contracts were inaccurate and, if true, would
have violated subtyping between editor<%> and text%.

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).

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.

When buttons are hidden and/or disabled so that there's a change to
the only button that is visible, enabled, and has the 'border style,
then make it the default.

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
original commit: da4bb5991f760fff53cd5e1792e6ee1d1fb2a961
the rearrangement moves the string constants documentation
into a package over by the string-constants implementation
and adds the string-constants (meta) pkg.
