Create a cache to drawing objects

Due speciall requirements for 2D drawing, the GP objects must be drawn after be sorteed by zdepth value.

We cannot use a simple GPU zdepth because this override the current layer/strokes order and the artists need to keep these controls as primary sorting method instead of GPU zdepth.

Create a shading group by stroke

As the drawing order is very important in 2D, each stroke must use its own shading group and don't share with others or the drawing order is missing and the layer system does not work.

Disable zdepth write for strokes

After some analysis, the strokes must work without affect the zdepth buffer or the layer system will not work.

The 2D artist agree that layer system must be the main zdepth order and not the GPU checking.

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.

Cleanup: Create several separated functions

Enable again write depth pass for strokes only

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

Remove write zdepth to avoid z-fighting

The strokes don't need to write the depth buffer

DwM: assert when uniforms aren't found

More useful when this error shows up early
