It is a know issue that split normals aren't supported when using high
quality normals in the viewport. Some AMD platforms were pushed to use
high quality normals to work around a driver bug where 1010102 texture
formats `GL_INT_2_10_10_10_REV` wasn't uploaded to the GPU.
This change will remove commonly used polaris platforms from the
work-around. This has been tested with a RX480 against the latest AMD
whql drivers (22.5.1). Users need to ensure that they use the latest
drivers that are available on their platform.
Although this change doesn't fix the underlying issue to support edit
normals when high quality normals are enabled. It will not force that
common platforms cannot use a feature as their platform is forced into
using a work-around.
* Port over new code tables from Cycles
* Convert Rec.709 to scene linear for lookup table.
* Move code for wavelength and blackbody to IMB so they can access the
required transforms, which are not in blenlib.
* Remove clamping from blackbody shader to bypass the texture read.
Since it's variable now easiest to just always read from the texture
than pass additional parameters.
* Fold XYZ to RGB conversion into the wavelength table.

This module allow tracking of object and geometry data accross time.
This commit adds no user visible changes.
It work in both viewport (*) and render mode, gives correct motion
for any camera projection type and is compatible with displacement (**).
It is a huge improvement upon the old EEVEE velocity which was only used
for motion blur and only available in render.
It is also an improvement for speed as the animated objects do not need to
be rendered a 3rd time. The code is also much cleaner: no GPUVertBuf
duplication, no GPUBatch amendment, no special cases for different geometry
types, no DRWShadingGroup per object, no double buffering of velocity.
The module is still work in progress as the final output may still be
flawed.
(*): Viewport support is already working but there might be some cases where
mapping will fail. For instance if topology changes but not vertex count.
(**): Displacement does not contribute to motion vectors. Surfaces using
displacement will have the same motion vectors as if they were not displaced.
This allows using the Graphic API to copy buffer data.
The GPU module do not expose untyped buffers even if that's what most API
do, so the copy function need to be strongly typed.
Contains GL backend implementation.
Since rB2a7a01b339ad, `lineSmooth` has lost its default value of true.
rBa0a99fb25284 only fixed the problem on master.
But thanks to @hitrpr for spotting the bug in version 3.2 too.

GLSL has different max number of ssbo per glsl stage.
This patch checks if the number of compute ssbo blocks matches
our requirements for the GPU Subdiv, before enabling it.
Some platforms allow more ssbo bindings then blocks per stage.

This is caused by the geometry shader used by the edit mode line drawing.
If the drawcall uses indexed drawing and if the index buffer only contains
restart indices, it seems the result is 1 glitchy invocation of the
geometry shader.
Workaround by tagging these special case index buffers and bypassing
their drawcall.
Viewports where cleared explicitly due to compatibility reasons with Intel iGPUs.
This slowed down other platforms as well, this wasn't noticeable on all platforms.
This patch will be more selective when to enable the workaround.
Currently only for iGPUs on Mac + Linux.
Introduced by {35594f4b92fa4cbb5b848f447b7a3323e572b676}.
Some platforms do not support temp variables to be used as inout parameter.
Detected on Mac with Intel iGPU.
Some drivers completely forbid quote characters even in unused
preprocessor directives.
This patch adds a debug build check for all `.glsl` files that need to
be manually handled. For shared headers with `#include` directives, we
need to do runtime patching of the source to remove the quote.
Also fix an instance of the quotes check failing in `eevee_next`.
This was caused by the `Closure` members being added to the final contribution
more than once. The workaround is to clear the members once a closure has
been added to the final contribution. I used `inout` on `Closure` inputs
so that the render engine implementation of mix and add closure nodes
can do its own thing. The nodegraph handling of inout was changed for this
to work.
Curve tangent was correctly mistaken with curve normal.
This patch fixes the name of the output in the glsl function and make curve
attributes more explicit (with `curve_` prefix).
This also improve the normal computation by making it per pixel to match
cycles.
Also ports the changes to eevee-next.
