Attached patch reftestSplinter 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.
