  Message : Fix support for GL_MAX_ATTRIBS attributes. *re-land with fix for AMD/ES2/OpenGL.* An off-by-one bug slipped in that broke support for these edge case shaders. Bug introduced in https://chromium-review.googlesource.com/#/c/266928/ BUG=angleproject:1045 BUG=500116 Change-Id: If44f809d432221d1e17afc407d49e87e0cb7504c Reviewed-on: https://chromium-review.googlesource.com/277664 Tested-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
