+/* This deeply hacky block of code exists for a rather convoluted reason.
+ *
+ * The proximal reason is that there are plugins (such as XLN's Addictive Drums
+ * 2) which redraw their GUI/editor windows using a timer, and use a drawing
+ * technique that on Retina displays ends up calling arg32_image_mark_RGB32, a
+ * function that for some reason (probably byte-swapping or pixel-doubling) is
+ * many times slower than the function used on non-Retina displays.
+ *
+ * We are not the first people to discover the problem with
+ * arg32_image_mark_RGB32.
+ *
+ * Justin Fraenkel, the lead author of Reaper, wrote a very detailed account of
+ * the performance issues with arg32_image_mark_RGB32 here:
+ * http://www.1014.org/?article=516
+ *
+ * The problem was also seen by Robert O'Callahan (lead developer of rr, the
+ * reverse debugger) as far back as 2010:
+ * http://robert.ocallahan.org/2010/05/cglayer-performance-trap-with-isflipped_03.html
+ *
+ * In fact, it is so slow that the drawing takes up close to 100% of a single
+ * core, and the event loop that the drawing occurs in never sleeps or "idles".
+ *
+ * In AU hosts built directly on top of Cocoa, or some other toolkits, this
+ * isn't inherently a major problem - it just makes the entire GUI of the
+ * application slow.
+ *
+ * However, there is an additional problem for Ardour because GTK+ is built on
+ * top of the GDK/Quartz event loop integration. This integration is rather
+ * baroque, mostly because it was written at a time when CFRunLoop did not
+ * offer a way to wait for "input" from file descriptors (which arrived in OS X
+ * 10.5). As a result, it uses a hair-raising design involving an additional
+ * thread. This design has a major problem, which is that it effectively
+ * creates two nested run loops.
+ *
+ * The GTK+/GDK/glib one runs until it has nothing to do, at which time it
+ * calls a function to wait until there is something to do. On Linux or Windows
+ * that would involve some variant or relative of poll(2), which puts the
+ * process to sleep until there is something to do.
+ *
+ * On OS X, glib ends up calling [CFRunLoop waitForNextEventMatchingMask] which
+ * will eventually put the process to sleep, but won't do so until the
+ * CFRunLoop also has nothing to do. This includes (at least) a complete redraw
+ * cycle. If redrawing takes too long, and there are timers expired for another
+ * redraw (e.g. Addictive Drums 2, again), then the CFRunLoop will just start
+ * another redraw cycle after processing any events and other stuff.
+ *
+ * If the CFRunLoop stays busy, then it will never return to the glib
+ * level at all, thus stopping any further GTK+ level activity (events,
+ * drawing) from taking place. In short, the current (spring 2016) design of
+ * the GDK/Quartz event loop integration relies on the idea that the internal
+ * CFRunLoop will go idle, and totally breaks if this does not happen.
+ *
+ * So take a fully functional Ardour, add in XLN's Addictive Drums 2, and a
+ * Retina display, and Apple's ridiculously slow blitting code, and the
+ * CFRunLoop never goes idle. As soon as Addictive Drums starts drawing (over
+ * and over again), the GTK+ event loop stops receiving events and stops
+ * drawing.
+ *
+ * One fix for this was to run a nested GTK+ event loop iteration (or two)
+ * whenever a plugin window was redrawn. This works in the sense that the
+ * immediate issue (no GTK+ events or drawing) is fixed. But the recursive GTK+
+ * event loop causes its own (very subtle) problems too.
+ *
+ * This code takes a rather radical approach. We use Objective C's ability to
+ * swizzle object methods. Specifically, we replace [NSView displayIfNeeded]
+ * with our own version which will skip redraws of plugin windows if we tell it
+ * too. If we haven't done that, or if the redraw is of a non-plugin window,
+ * then we invoke the original displayIfNeeded method.
+ *
+ * After every 10 redraws of a given plugin GUI/editor window, we queue up a
+ * GTK/glib idle callback to measure the interval between those idle
+ * callbacks. We do this globally across all plugin windows, so if the callback
+ * is already queued, we don't requeue it.
+ *
+ * If the interval is longer than 40msec (a 25fps redraw rate), we set
+ * block_plugin_redraws to some number. Each successive call to our interposed
+ * displayIfNeeded method will (a) check this value and if non-zero (b) check
+ * if the call is for a plugin-related NSView/NSWindow. If it is, then we will
+ * skip the redisplay entirely, hopefully avoiding any calls to
+ * argb32_image_mark_RGB32 or any other slow drawing code, and thus allowing
+ * the CFRunLoop to go idle. If the value is zero or the call is for a
+ * non-plugin window, then we just invoke the "original" displayIfNeeded
+ * method.
+ *
+ * This hack adds a tiny bit of overhead onto redrawing of the entire
+ * application. But in the common case this consists of 1 conditional (the
+ * check on block_plugin_redraws, which will find it to be zero) and the
+ * invocation of the original method. Given how much work is typically done
+ * during drawing, this seems acceptable.
+ *
+ * The correct fix for this is to redesign the relationship between
+ * GTK+/GDK/glib so that a glib run loop is actually a CFRunLoop, with all
+ * GSources represented as CFRunLoopSources, without any nesting and without
+ * any additional thread. This is not a task to be undertaken lightly, and is
+ * certainly substantially more work than this was. It may never be possible to
+ * do that work in a way that could be integrated back into glib, because of
+ * the rather specific semantics and types of GSources, but it would almost
+ * certainly be possible to make it work for Ardour.
