commit 12dcf5e6e770b1933252a1f919663ba45ded4cdf
Author: Michael Meeks <michael.me...@collabora.com>
Date: Fri Nov 13 09:56:53 2015 +0000
slideshow: cleanup main-loop usage, post-yield listeners, etc.
This removes several attempts at reducing jitter in slideshow
animations. Now we have high-resolution (ie. not clamped to 10ms)
timers on Windows and a cleaner and simpler main-loop, we should
be able to use generic timer code-paths for all of this.
This also allows us to further cleanup and simplify the main-loop
removing the now redundent post-yield handler concept. If there is a
short enough timeout, we will take just 1ms of delay before executing
a short timer anyway.
Also removed some lingering comments from an old attempt to boost
priorities which broken audio playback.
Tested: tdf#32861 - still works, audio still plays, no new jitter
in animations that I tested.
