  Message : Refactor GL tests to use a shader library Instead of having the same simple shaders repeated over and over in the test code, reuse a single shader library. BUG=angleproject:2474 TEST=angle_end2end_tests Change-Id: I13f8ca8c0125e6d30f1761639bf8c3f69e0e77d2 Reviewed-on: https://chromium-review.googlesource.com/1012078 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Olli Etuaho <oetuaho@nvidia.com>
