This improves shadow quality by reducing the visibility of the noisy
pattern caused by dithering.
This jittering also applies when FSR2 is enabled, as it provides its own
form of temporal antialiasing.

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)
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.
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.
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.
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.
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.
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
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.
