  Message : EGLWindow: remove the unused width and height EGLWindow does nothing with it per se, but some code was relying on it to store it. Add width and height to ANGLETest and SampleApplication instead. Also fix a typo in PerfTestParams, widowWidth -> windowWidth. BUG=angleproject:1105 Change-Id: I26da607a2e6342864b508a50ee3cf8944608f868 Reviewed-on: https://chromium-review.googlesource.com/287379 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Tested-by: Corentin Wallez <cwallez@chromium.org>
