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.
Introduces a new structure to store samplers created with certain parameters instead of storing a 'custom' set of samplers. Allows viewports to correctly configure the mipmap bias and use it when rendering the scene.
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.
Fixes#67287. There was a subtle error where due to how enabling motion vectors for multi-meshes was handled, only the first instance would have a valid transforms buffer and the rest would point to an invalid buffer. This change moves over the responsibility of enabling motion vectors only when changes happen to the individual 3D transforms or the entire buffer itself. It also fixes an unnecessary download of the existing buffer that'd get overwritten by the current cache if it exists. Another fix is handling the case where the buffer was not set, and enabling motion vectors would not cause the buffer to be recreated correctly.
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.
