Brian Osman eee3c09e96 Unit test to demonstrate Galaxy S6 MSAA readPixels bug
After lots of tinkering, this is the smallest test case I've
found to reproduce the bug. Frequently, bitmap b4 will be
cleared to blue, but not contain the oval drawn right before.
Bitmap b5 will contain the oval, so the diff of the two
bitmaps will detect the error.

There may be something else that can be removed, but I
haven't found it.

Interesting note:

In the original version, all surfaces were cleared to
black. When I started trying to change the clear colors to
figure out if we were getting an old surface, the bug went
away. In particular, the first clear color is irrelevant,
but the last three clears must all be the same color. If
any are different, the bug doesn't occur.

This directory contains infra-specific files. The branch-config/ directory contains configs that are specific to the master branch (e.g. config for the CQ committing to the master branch), while project-config/ directory contains project-wide configuration (e.g. list of buckets for cr-buildbucket service and list of refs known to the infra services).
