d61fae36f3 Various fixes for transmittance effect 
Use correct shadow sampling for omni and spot lights

Disable transmittance if shadows are disabled

Correct DirectionalLight transmittance bias to match shadow bias (its still pretty sensitive though)

e41064388e reverted naming to premul alpha (no T) 
Initially 3d had premulT alpha as a keyword.
Since Canvas item uses mixed premul and premult as keywords,
3D is changed as well to keep consistency with 2D.
Unfortunately this keeps inconsistency with the internal ENUM.

a5399ab5af Reduce the number of samplers used by the scene shaders 
The hard limit for Apple devices is 16 samplers per stage. So we need to ensure we use less than that

2b9e6d2972 Use render pass uniform set to store viewport samplers. 
This fixes a bugs where per-viewport samplers were being used for internal texture fetches (probes, sky, etc.).

This also fixes a bug when using multiple viewports in the same scene.

This also fixes a bug where the texture bias would override the bias from 3D scale.

51ed3aef63 Vertex and attribute compression to reduce the size of the vertex format. 
This allows Godot to automatically compress meshes to save a lot of bandwidth.

In general, this requires no interaction from the user and should result in
no noticable quality loss.

This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.

Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.

057367bf4f Add FidelityFX Super Resolution 2.2 (FSR 2.2.1) support. 
Introduces support for FSR2 as a new upscaler option available from the project settings. Also introduces an specific render list for surfaces that require motion and the ability to derive motion vectors from depth buffer and camera motion.

e2984af013 Add motion vector support for animated surfaces like skeletons or blend shapes. 
Extends mesh instances that required custom vertex buffers to create two alternating buffers that are written to and binds them to use them as the previous vertex buffer when generating motion vectors.

7c812cd7e9 Fix use of discard in shaders 
discard was being included in all shaders set to depth pass opaque, which is the majority of shaders

Instead it should only be used with alpha prepass materials

63c6f0b93c Use MODELVIEW_MATRIX for vertex transform when double precision is enabled 
This commit updates the double precision vertex transform code from
using the MODEL_MATRIX to now use the MODELVIEW_MATRIX instead.

This can be made possible by transforming the MODELVIEW_MATRIX
back into model space (ie, same space as the MODEL_MATRIX) and then using it as if it were the MODEL_MATRIX.

With this in place we now properly handle VERTEX transformations that
a Material Shader might do, such as billboard-ing.
