- Adding in compatibility paths to support minimum per-vertex strides for vertex formats. OpenGL supports a minimum stride of 1 byte, in Metal, this minimum stride is 4 bytes. Meaing a vertex format must be atleast 4-bytes in size.
- Replacing transform feedback compile-time check to conditional look-up, given TF is supported on macOS with Metal.
- 3D texture size safety check added as a general capability, rather than being in the gl backend only. Also required for Metal.

Several visual tweaks to node links to make them overall fit in
better with the look of the node editor:
- Change the link thickness with the zoom level to a certain degree.
- Remove the fuzziness of the node link and its shadow/outline.
- The link outline color can now be made transparent.
- Add circles at the end of dragged links when connecting to sockets.
- Improve the banding of the color interpolation along the link.
- Adjust the spacing of dashes along straight node links.

With the new `attrs_info_get` method, we can get information about
the attributes used in a `GPUShader` and thus have more freedom in the

This patch moves material indices from the mesh `MPoly` struct to a
generic integer attribute. The builtin material index was already
exposed in geometry nodes, but this makes it a "proper" attribute
accessible with Python and visible in the "Attributes" panel.
The goals of the refactor are code simplification and memory and
performance improvements, mainly because the attribute doesn't have
to be stored and processed if there are no materials. However, until
4.0, material indices will still be read and written in the old
format, meaning there may be a temporary increase in memory usage.
Further notes:
* Completely removing the `MPoly.mat_nr` after 4.0 may require
changes to DNA or introducing a new `MPoly` type.
* Geometry nodes regression tests didn't look at material indices,
so the change reveals a bug in the realize instances node that I fixed.
* Access to material indices from the RNA `MeshPolygon` type is slower
with this patch. The `material_index` attribute can be used instead.
* Cycles is changed to read from the attribute instead.
* BMesh isn't changed in this patch. Theoretically it could be though,
to save 2 bytes per face when less than two materials are used.
* Eventually we could use a 16 bit integer attribute type instead.

This checks for the availability of `gl_BaseInstanceARB` or equivalent.
Disabling for any workaround that disables shader_image_load_store_support
as a preventive measure.
This patch is a response to T92588 and is implemented
as a Function/Shader node.
This node has support for Float, Vector and Color data types.
For Vector it supports uniform and non-uniform mixing.
For Color it now has the option to remove factor clamping.
It replaces the Mix RGB for Shader and Geometry node trees.
As discussed in T96219, this patch converts existing nodes
in .blend files. The old node is still available in the
Python API but hidden from the menus.

This allows the render engine to expect non-overlapping resources in the
generated create info.
Textures are indexed from 0 and up.
Nodetree ubo is bound to slot 0.
Uniform attributes ubo is bound to slot 1.
The calculation was revised to address two issues:
* Discontinuities occurring when detail was a non-integer greater than 2.
* Levels of detail in the interval [0,1) repeating the levels of detail in
the interval [1,2).
This fixes Cycles, Eevee and geometry nodes.

The number of attribute domains isn't an attribute domain, so storing
ATTR_DOMAIN_NUM in a variable with an eAttrDomain type isn't correct.
In the cases it was used, the value wouldn't be accessed anyway.
The realtime compositor sometimes produces fuzzy results when the
interpolation is set to bilinear. This was due to the domain realization
shader, which incorrectly sampled the input image.
This patch fixes such fuzziness by introducing a 0.5 offset to evaluate
the sampler at the center of pixels. Additionally, it makes sure the
centring offset is an integer offset by taking its floor, retaining the
previous 0.5 offset even with the difference in size is odd.
There was a memory leak in the GPU code generator for the compositor
output. It was just due to a missing free in the GPU code generator
destructor, so this patch makes sure it is freed.

This new implementation does all downsampling in a single compute shader
dispatch, removing a lot of complexity from the previous recursive
downsampling.
This is heavilly inspired by the Single-Pass-Downsampler from GPUOpen:
https://github.com/GPUOpen-Effects/FidelityFX-SPD
However I do not implement all the optimization bits as they require
vulkan (GL_KHR_shader_subgroup) and is not as versatile (it is only
for HiZ).
Timers inside renderdoc report ~0.4ms of saving on a 2048*1024 render for
the whole downsampling. Note that the previous implementation only
processed 6 mips where the new one processes 8 mips.
```
EEVEE ~1.0ms
EEVEE-Next ~0.6ms
```
Padding has been bumped to be of 128px for processing 8 mips.
A new debug option has been added (debug value 2) to validate the HiZ.
This cleans up the OpenGL build flags and linking.
It additionally also removes some dead code.
One of these dead code paths is WITH_X11_ALPHA which actually never was
active even with the build flag on. The call to use this was never
called because the default initializer for GHOST was set to have it off
per default. Nothing called this function with a boolean value to enable it.
These cleanups are needed to support true headless OpenGL rendering.
Without these cleanups libepoxy will fail to load the correct OpenGL
Libraries as we have already linked them to the blender binary.

With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

Compared to the previous implementation this has a limit of 65536 lights
per scene. Lights exceeding this limit will be ignored.
This also introduce fine grained GPU light culling, making rendering
many lights in a scene more efficient as long they don't overlap much.
Compatible light panels have been unhidden.
Note: This commit does not include surface evaluation, only light culling.
