  Hash : 9277ee74
  Message : Metal: Implement MSAA default framebuffer. GL_SAMPLE_COVERAGE_VALUE is implemented by inserting gl_SampleMask writing logic to fragment shader. New test added: MultisampleTest.ContentPresevedAfterInterruption. - Skip on D3D11 (Bug: angleproject:4609) Bug: angleproject:2634 Change-Id: Ib44daf0baccc36ea320596d81713156047da059c Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2281783 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>

  //   A GLSL-based translator that outputs shaders that fit GL_KHR_vulkan_glsl.
  //   The shaders are then fed into glslang to spit out SPIR-V (libANGLE-side).
