658c2b6eee Bring accidentally commented out lines back. 
Oversight by me in #22483. GLES2 doesn't seem to be supporting anisotropy at the moment anyway ---in case it gets revived.

c24277a520 -Many GLES2 optimizations 
-Android export fixes (use ETC if GLES2 backend in use)
-revert to thekla atlas because xatlas is not working well

9f4e9fcb81 Optimized GGX G function for GLES2. 
Also changed the mapping of anisotropy to match the common definition.

e94f6aacee Restore the Fresnel term in the BRDF. 
Was uncommented in 65fd37c, mostly likely by mistake since its important.

Also made a few corrections of specular -> specular_blob_intensity (gles2).

4226d56ca9 Style: Enable clang-format on GLSL shaders 
As of clang-format 6.0.1, putting the `/* clang-format off */` hint
around our "invalid" `[vertex]` and `[shader]` statements isn't enough
to prevent a bogus indent of the next comments and first valid statement,
so we need to enclose that first valid statement in the unformatted chunk.

73fe08be2e GLES2 refactors 
This commit unhacks some parts of the 3D rendering.

Most notably:

 - possibility to use negative texture units
   (no longer weird manual index allocation for user samplers)

 - refactoring of light code, now sorts in a different way,
   should yield better performance

 - fixes a crash while saving (because of "Illegal instruction" execution)
   when using a decent compiler (clang, it's clang. Thanks GCC for not telling me about UB).

Tweak the default SpatialMaterial properties 
Roughness is now set to 1 by default and albedo is now white,
even on meshes that do not have any materials defined.

This means there is no longer a visual difference between a
mesh with no materials defined and a mesh with a default
SpatialMaterial defined.

eac4c984df add GLES 2 renderer for 2D 
This commit adds a new rendering backend, GLES2, and adds a
project setting to enable it.

Currently this backend can only be used on the X11 platform,
but integrating into other platforms is planned.
