5736535b8a avoid spurious screen refresh on text-measure operations 
The drawing layer now indicates whether drawing content was
changed as it releases a drawing handle.

021f9a6a0a delay the creation of the information in the info text 
this has the advantage of that the information is inserted when the
state of the text is set up so that font sizing works

it also means that if there is a syntax object with a syntax
object on its properties with another one like that etc etc etc
they will only be rendered when they are made visible which
theoretically could be a performance improvement for some people

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).

With GTK+ 3 on Raspbian, at least, the old management of the

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.

in some cases. Delay the refresh to restore the old timing
without the old bug.
