GLSL now emits 4x2 diagonal matrices as: `(mat4x2(1.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0) * n)` instead of `mat4x2(n)`. This works around a long-standing GLSL bug in both Mesa and glslang that affects several drivers: https://github.com/KhronosGroup/glslang/issues/2645 Change-Id: If529d5cd150ce720f436cb3634a2fd3423919278 Bug: skia:12003 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/410137 Auto-Submit: John Stiles <johnstiles@google.com> Commit-Queue: Brian Osman <brianosman@google.com> Reviewed-by: Brian Osman <brianosman@google.com>
