Tests to add for M63:
1. Need to add foreground blur perf test.
2. Need to add cache render surface to foreground blur to see the improvement.

Possible for M64:
After the new background blur mechanism launched, need to compare with current method and used combine with cache render surface.

Are these resolved? Should these be closed?

This is still available.
There are more tests need to be added for missing Chrome UI performance tests for layer blur effect.

Assign to dcastagna@ for new implementation.

Assigning it back to Andres that worked on crrev.com/c/1324240

Create a story to detect blur backdrop filter regressions.

This CL creates a story which consists of a JS animation in which a
group of red squares rotates in the background while three
semi-transparent foregrounds move on top (with some rotation,
translation, and resizing going on). The foregrounds apply a blur
filter.

The motivation is that in Chrome OS, we were having problems with the
launcher animation having a low frame rate. As the launcher is swiped
upwards, it applies a blur on the background. dcastagna@ landed a fix to
improve this significantly (see  https://crbug.com/900046 ). The code used
by the launcher to do the blurring is not unique to Chrome OS, so the
new story should be able to measure regressions in that animation.

For due credit: the story is based on tbuckley@'s example which
reproduced the issue on the web (see
https://codepen.io/anon/pen/MPXYMQ).

Enable rendering.desktop/backdrop_filter test in CrOS.

This CL ensures that the rendering.desktop/backdrop_filter runs in CrOS
so that we can detect regressions of the launcher animation which may
involve background blurring.

TEST=ran run_benchmark with the modified story_tag_filter argument.

Put the backdrop_filter perf test in a separate control file.

This CL creates control.backdrop_filter.renderer.desktop so that the
backdrop_filter stories can run independently of other rendering.desktop
stories since the browser needs to have the
--enable-experimental-web-platform-features flag. The new file is
unmanaged by generate_controlfiles.py but is based on the existing
control.rendering.desktop file.

TEST=run_benchmark with --story-tag-filter=backdrop_filter runs as
expected.
