Attached patch reftest (deleted) — Splinter Review

The reftest fails on non WebRender on Android, and I've succeeded in writing another variant of the reftest which has no animation. Attaching file is the reftest. So, I am ~100% sure the failure reason is in our layerization code instead of partial pre-render code.

I am going to skip the reftest on geckoview&&!webrender in bug 1656418.

Note that the refest does fail only if it runs with --run-until-failure. (at least on my environment)

I noticed that the test doesn't fail with layers.enable-tiles=false, also noticed with layers.tiles.edge-padding=false the test fails on a single run. There may be some rounding errors in tiled layer code.
