My mistake, I added this when rebasing and didn't notice that it was a
.glsl file and thus the availability of Math was not confirmed by the
C++ compiler.
A new `Math::division_round_up()` function was added, allowing for easy
and correct computation of integer divisions when the result needs to
be rounded up.
Fixes#80358.

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.
Add the capability of resizing the transforms buffer for particles to be double its size and alternate where the current output is written to. Only works for particles that use index as their draw order.
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.
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance
Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.
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
Commit 2c000cb72f changed the interpolation limits from (0.04, 1.0) to (0.04, 0.37). This is incorrect, as we want to have an F0 of 0.04 for dielectrics (materials with metalness of 0.0) and an F0 of 1.0 for metals.
The Schlick approximation uses an F0 of 0.04 for all dielectrics and it's good enough.
Having it lower than 1.0 leads to an incorrect application of the Fresnel effect for metals and leads to bugs like #79549
