Unsure as to why we were the only browser to fail this test related to cubic-bezier accuracy,
I adjusted our UnitBezier code to match Chromium's ui/gfx/geometry/cubic_bezier.cc and this
solved this browser-specific failure.

This also addressed the issue where css/css-easing/cubic-bezier-timing-functions-output.html
was a unique failure in WebKit.
