cc: Add layer-based pixel tests.
This adds a test framework for pixel tests based on a layer tree. Included
is a single new pixel test to demonstrate the framework, which is a test
derived from the layout test
platform/chromium/compositing/filters/background-filter-blur.html
reproduced with solid color layers.
New test:
LayerTreeHostFiltersPixelTest.BackgroundFilterBlur
