Hash : 0df92012
Message : Rename Platform.h to PlatformMethods.h. "platform.h" is too common a name and causes headers to be included incorrectly. Disambiguate the header using a more specific name. Solves a problem that came up with the GLES 1 tests and the standalone test harness. Bug: angleproject:3162 Change-Id: I88229a2c9407e0db57f5beee44daa11a4075f700 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2229065 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Yuly Novikov <ynovikov@chromium.org>
