This was caused by TAA offset being computed as the 2nd sample even if the
sampling was reset afterwards.
The fix is to update the matrices after any potential reset.
This cleans up a bit of duplicated code and some confusion about
what was culled and what wasn't.
Now everything is culled based on the given object pointer.
If the object pointer is NULL there is no culling performed.
When viewport samples are set to 1 simple scenes with volumetrics crash.
EEVEE volumetrics needs to init the post processing buffers. With recent
changes the need for post processing buffers are known after the cache
init. But they are constructed before the cache init. This lead to null
pointers.

This is to simplify the usage of Volumetrics.
Now it automatically detect if there is any Volumetric material in the
view and allocate the needed buffer if any.
Make Lookdev works with bloom and TAA by rendering it before TAA and fixing
the motion vectors of the lookdev balls.
Rework Lookdev to remove much of its complexity. Use simpler matrices with
more understandable setup code.
Viewport now displays alpha checkerboard pattern like Cycles does when
film alpha is set to "Transparent".
Some small workarounds were necessary for Depth of Field and correct TAA
support.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading

It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
The crash only occurs with Intel 3rd generation GPUs.
It occurs because the program needs to be used at least once in the opengl context in which it is created.
It is caused by some sync issue apparently. Adding glFlush in these
two places fixes it.
Caveat: it might have a small perf impact (did not measure it).
The fix is limited to the affected driver/operating systems.
There was an issue caused by Antialiasing being done after DoF. Move TAA
after DOF and Motion Blur.
Also certain pixel with lower CoC would be spread all over the background
because the neighbooring pixel have higher CoC. So we need to apply some
bilateral filtering when downsampling. Currently we limit the influence of
neighbor pixels with a CoC inside the range [MaxCoC-2, MaxCoC].
Because:
- Less redundancy.
- Better suffixes.
Also a few modification to GPU_texture_create_* to simplify the API:
- make the format explicit to the texture creation process.
- remove the component count as it's specified in the GPUTextureFormat.
This "improve" the viewport experience by reducing the noise from random
sampling effects (SSAO, Contact Shadows, SSR) when moving the viewport or
during playback.
This does not do Anti Aliasing because this would conflict with the outline
pass. We could enable AA jittering in "only render" mode though.
There are many things to improve but this is a solid basis to build upon.
This pass create a velocity buffer which is basically a 2D motion vector
texture. This is not yet used for rendering but will be usefull for motion
blur and temporal reprojection.
