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 also makes the Overdraw and Shadow Splits debug draw modes ignore fog.
The Lighting debug draw mode still displays fog as that debug draw mode
is intended to preview scene lighting, and fog has an impact on how
lighting is perceived.
Adds a new system to automatically reorder commands, perform layout transitions and insert synchronization barriers based on the commands issued to RenderingDevice.
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.
Ensure `ensure_tangents` option actually creates tangent array. Even if it is just a dummy array.
Allow mesh to generate its own tangents when using compression. This allows users to compress meshes without tangents.
Warn users if they are trying to read from tangents without providing tangents.
Fixes issue #83152. Due to how BLUR_0 is reused for multiple purposes and requires being at native resolution for some post-processing effects to work, FSR2 will use an alternate texture at internal size to use as the screen texture read by shaders instead. The rendering pipeline will prefer using this texture if it exists.
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.
