This could use a unit test too, on the same level as TEST_F(LayerTest,
CheckPropertyChangeCausesCorrectBehavior) in layer_unittest.cc to make sure that
changing properties to new values causes a commit.

I copied this from layer_unittest.cc.  Is there a generic place for cc/ test
#defines?  I didn't immediately see one when I looked.

You could move it to layer_test_common.h if you wanted a common location to put
it and not duplicate code.

The commit queue went berserk retrying too often for a
seemingly flaky test. Builder is android_dbg, revision is HEAD
