Fix bug in updating vertex attribs with client memory pointers In DEBUG version, when using OpenGL back-ends, ANGLE may meet an INVALID_OPERATION error from driver when attemping to update an attribute which is disabled and using a client memory pointer. This patch fixes this bug by skipping such vertex attributes when updating them to driver. With this patch the process to update vertex attributes should be: (1) For enabled attributes using client memory pointer: update by streaming mode in streamAttributes() (2) For disabled attributes using client memory pointer: just label them dirty and skip them (3) For attributes using buffer objects: update with vertexAttrib*Pointer BUG=angleproject:1942 Change-Id: I57043e5904eb4a342fa22d449d98a957010170d6 Reviewed-on: https://chromium-review.googlesource.com/456747 Commit-Queue: Geoff Lang <geofflang@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org>
