Message : Tests: Prettify output for EXPECT_PIXEL_EQ. Previously our output would spam multiple lines by checking equality for each color component. Instead, use a helper struct with a stream operator to clean up the output. This makes it much more legible. New output style: Expected: (0, 255, 0, 255) Actual: angle::MakeGLColor(255, 0, 127, 255) Which is: (255, 0, 127, 255) BUG=angleproject:1290 Change-Id: Ieea018ab6c149a20b5fd74d74c972118b63a4b5e Reviewed-on: https://chromium-review.googlesource.com/323441 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Tryjob-Request: Jamie Madill <jmadill@chromium.org> Tested-by: Jamie Madill <jmadill@chromium.org>
