  Message : Apply Chromium style fixes. This addresses several minor code quality issues that are validated in Chromium, but not yet applied to ANGLE: * constructors and destructors must be defined out-of-line * auto is not allowed for simple pointer types * use override everywhere instead of virtual * virtual functions must also be defined out-of-line Slightly reduces binary size for me (~2k on Win, 150k on Linux). Bug: angleproject:1569 Change-Id: I073ca3365188caf5f29fb28d9eb207903c1843e6 Reviewed-on: https://chromium-review.googlesource.com/779959 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
