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 cleans up a few more cases of uint32_t->uint64_t
Importantly this fixes an edge case in the axis-angle compression by
using the pre-existing Basis methods instead
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 is a longstanding issue in both the Mobile and GL Compatibility renderer.
Meshes pair with all lights that touch them, and then at draw time, we send all paired lights indices to the shader (even if that light isn't visible). The problem is that non-visible lights aren't uploaded to the GPU and don't have an index. So we end up using a bogus index
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.
TAA + MSAA would make Godot request unnecessary flags for an MSAA
velocity texture. flags that were not even actually needed.
This was causing:
1. Unsupported GPUs to fail completely (e.g. Intel Arc 770)
2. Wrong codepaths to be followed (causing validation errors, possibly
crashes or glitches)
3. Unnecessary performance impact in all GPUs.

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.
There was an error in the other branch of the refactored function where the size of the array was not properly multiplied by the size of the float to check against the buffer size. This was only an error in the error-checking itself and not the functionality. There was also an error where the proper notification was not emitted whenever the buffer for the multimesh is recreated to invalidate the previous references the renderer might've created to it. This fixes CPU Particles getting corrupted when they're created without emission being enabled.
Direct buffer copies are required to perform certain operations more efficiently, as the only current alternative is to download the buffer to the CPU and upload it again. As the first use case, the new function is used when enabling motion vectors on multimeshes.
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.
See Issue #69528. When building with precision=double, the TAA pass would break due to the motion vectors being corrupted. It was apparent the origin of the camera itself was corrupted in the UBO for the previous frame because the camera origin was only being split correctly for the current block but not for the previous block (to effectively support the double precision float on the shader).
