This avoids a shader compile error when using SSS and PREMUL_ALPHA_FACTOR in the same shader.
This doesn't change any functionaility, since in practive, the split-specular shader variant is only ever used for opaque objects while using premul alpha makes the object non-opaque
This can result in low fog densities being a bit brighter, which may need slight adjustment in your scenes.
In exchange, volumetrics now blend smoothly together with the scene and regular fog.
Fixes#101514
draw_call.instance_index should not be used directly since it doesn't take into account auto-batching
scene_data_block.data should not be used directly in the vertex shader since it can change between frames and impact motion vector generation
IN_SHADOW_PASS can only be accessed inside functions, so it needs to be a global and not a constant
Add new shader built in Z_CLIP_SCALE to easily adjust clipping distance to avoid clipping walls etc.
Add fov_override to StandardMaterial3D to easily have a custom FOV for FPS objects
Add IN_SHADOW_PASS built-in to shaders for tweaking materials without impacting shadow maps
Moves the initialization of the geo_normal value
to after the user shader code, so that the normal
supplied by the user is actually used instead of
the interpolated vertex normal.
Fixes two errors related to the normal, tangent,
and bitangent vectors, namely normals not always
being inverted on backfaces, and normalization
being reversed from what MikkTSpace expects.
- Implements asynchronous transfer queues from PR #87590.
- Adds ubershaders that can run with specialization constants specified as push constants.
- Pipelines with specialization constants can compile in the background.
- Added monitoring for pipeline compilations.
- Materials and shaders can now be created asynchronously on background threads.
- Meshes that are loaded on background threads can also compile pipelines as part of the loading process.
This adds support in all backends, but the Compatibility renderer works the best.
Mobile and Forward+ can only support one directional light shader (the first in the tree)
While the Compatibility renderer supports any number of shadows.

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.
