From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Kenneth Russell <kbr@chromium.org>

Subject: In WebGL, constrain base level of compressed textures.
Enforce that if a mipmap level > 0 is specified for a compressed
texture, that it implies that the size of the base level of the
texture is a multiple of the format's block size.
Makes the test changes in
https://github.com/KhronosGroup/WebGL/pull/3304 largely pass. There
are some needed follow-on fixes to that PR, and this CL changes a
sub-test result in the existing S3TC and S3TC-sRGB tests which will
need to be suppressed Chromium-side first.
