I think nothing calls the setter? Remove it?

Yes. That was a question. We have --enable-ui-compositor-timelines for ui::
compositor to switch that bool on. It looks like we need a separate command line
flag for android compositor. --enable-android-compositor-timelines?

[loyso (OOO), 2015/05/20 02:48:53]

Now we use switches::kEnableAndroidCompositorAnimationTimelines and we call the
setter from content/browser/android/content_startup_flags.cc
Is that the right place to do so?
