Revert assert, Eevee uses uniforms that might not exist

Cleanup: move custom-data layers into a struct

Changed because the values co-exist with active layers
(Mesh.mloopuv, Mesh.mloopcol).

Cleanup: line length

Cleanup: minor edits

Fix compilation on gcc

Gawain: remove GLenum from IndexType API

Goal is to make most of the API independent of OpenGL, Vulkan, any other backend.

Able to remove default case from ElementList_size because IndexType only covers index types. Not that and *everything else* like GLenum.

Gawain: use integer math to convert int16 to int10

@fclem does this work for you?

Gawain: cleanup code formatting

Gawain: drop support for APPLE_flush_buffer_range

Modern GL's glMapBufferRange works the same on all platforms.

Part of T49012

Gawain: drop support for APPLE_vertex_array_object

Recent versions of OpenGL support VAOs natively.

Gawain: promote 10_10_10 to first-class vertex format

This format is part of OpenGL 3.3, and one of the reasons for choosing 3.3 over 3.2.

Instead of checking #if USE_10_10_10 just use it wherever needed.

Cycles Denoising: Skip feature pass writing for volume-only shaders

Volume shaders without anything connected to the surface output are treated
as if they had a transparent BSDF as the surface shader in Cycles, so the
denoiser should skip feature pass writing for them just as it does with an
actual transparent BSDF.

Cycles Denoising: Skip confidence interval test for outlier central pixels

If the central pixel is an outlier, the denoiser is supposed to predict its
value from the surrounding pixels. However, in some cases the confidence
interval test would reject every single surrounding pixel, which leaves the
model fitting with no data to work with.

Eevee: Initial implementation of exponential shadowmaps

Also fixes the rendering of depth.

Eevee: Move cube shadows to octahedron shadowmaps.

We render linear distance to the light in a R32 texture and store it into an octahedron projection inside a 2D texture array.

This render the sampling function much more simpler and without edge artifacts.

GPUTexture: Enabling R32 format for linear depth encoding.

Eevee: optimize vertex shader for probe and shadows.

Cleanup: warnings

DwM: assert when uniforms aren't found

More useful when this error shows up early
