All these tests in the test suite are really slow [1], and these two in particular: BlendingWithRenderPassWithMaskColorMatrixAA_GL BlendingWithRenderPassShadersWithMaskColorMatrixAA_GL [1]: https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=cc_unittests%20(with%20patch)&tests=LayerTreeHostBlendingPixelTest.BlendingWith*

Vladimir, can you please help triage this? Looks like all of these tests are really slow, and often cause try job failures. I wonder if they can be sped up, or the time limits increased.
