345a20c5e8 use NSOpenGLPFAAllowOfflineRenderers for GC bitmap 
Try to tell Macs with two graphics cards that it's ok to
use the low-performance one for the GC bitmap (when
GL is used for that, which is OS X 10.11 and later).

edc56ee8de Windows: change play-sound to use MCI 
Provided by Eli Barzilay.

This approach is better than a separate process, because creating
too many processes can overwhelm the OS. Also, MCI supports more
sound formats.

41d4e9dd2d Cocoa: fix refresh and fullscreen problems 
Add more agressive re-enabling of screen updates and explicit `update`
calls to avoid partially refreshed frames and never-updated titlebars
on El Capitan.

Also, use `close` instead of `orderOut` to hide a frame. That fixes
problems with closing windows that are in fullscreen mode.

Closes racket/drracket#33

1944cd8dbd regsiter-collecting-blit: support background bitmap in El Capitan 
The GC blit implementation used on Mc OS X 10.11 assumed that
the no-GC bitmap is blank. Make it use the given no-GC bitmap.

Also, repair the left-to-right flipping(!) of the GC bitmap,
and repair a backing-scale mismatch that could leave a thin
border around a GC blit.

3873064c80 Cocoa: avoid over-eager refresh on OS X 10.11 
A relatively late correction to refresh handling for El Capitan
(commit 9bf18505d5) causes a canvas to be refreshed too often
in some cases. Delay the refresh to restore the old timing
without the old bug.

b842b1feec Mac OS X 10.11: register control font to make it Pango-accessible 
The new system control font is (intentially) not associated with a
font family, so it's inaccessible via Pango. A patch to Pango lets
us synthesize and register new families, so the control font can
be made accessible.

cdc992ccb9 fix problems and consistency with fullscreen in frame% 
The `fullscreen` method implied `show` on Mac OS X and Windows, but
not on Gtk, and a frae shown that was was not properly registered
as shown (e.g., the application could exit). For consistency, adjust
`fullscreen` to not imply `show`. Also, shift to a remaining frame
on Mac OS X when a fullscreen frame is closed.

ea576d3177 Mac OS X 10.11: disable auto-update for suspended-flush windows 
Previous versions of OS X seem to have automatically disabled
update for a window when flushing is disabled, but now we have to
do it ourselves, otherwise text editors can flicker a lot. (The
system change is probably related to the removal of the
`isFlushWindowDisabled` method of `NSWindow` (which was
deprecated in 10.10).
