+++ This bug was initially created as a clone of Bug #1142957 +++

If we fail to initialize hardware vsync on OS X, fallback to software vsync.
From bug 1144638, we now retry to get a CVDisplayLink when coming back from sleep or changing monitors. This has seemed to been resolved since the compositor has landed. Upon startup of firefox, we already fallback to software vsync if CVDisplayLink's in general are unavailable[1]. Resolving as WFM.
