This way it is way clearer what each viewport state is. There is
no more save and reset. The scissor test is also saved per
framebuffer.
The only rule to remember is that the viewport state (size and
origin) is reset for both the viewport and scissor when a texture
is attached or detached from an attachment slot.
This follows the GPU module naming of other buffers.
We pass name to distinguish each GPUUniformBuf in debug mode.
Also remove DRW_uniform_buffer interface.
- add the use of DRWShaderLibrary to EEVEE's glsl codebase to reduce code
complexity and duplication.
- split bsdf_common_lib.glsl into multiple sub library which are now shared
with other engines.
- the surface shader code is now more organised and have its own files.
- change default world to use a material nodetree and make lookdev shader
more clear.

These are the modifications:
-With DRW modification we reduce the number of passes we need to populate.
-Rename passes for consistent naming.
-Reduce complexity in code compilation
-Cleanup how renderpass accumulation passes are setup, using pass instances.
-Make sculpt mode compatible with shadows
-Make hair passes compatible with SSS
-Error shader and lookdev materials now use standalone materials.
-Support default shader (world and material) using a default nodetree internally.
-Change BLEND_CLIP to be emulated by gpu nodetree. Making less shader variations.
-Use BLI_memblock for cache memory allocation.
-Renderpasses are handled by switching a UBO ref bind.
One major hack in this patch is the use of modified pointer as ghash keys.
This rely on the assumption that the keys will never overlap because the
number of options per key will never be bigger than the pointed struct.
The use of one single nodetree to support default material is also a bit hacky
since it won't support concurent usage of this nodetree.
(see EEVEE_shader_default_surface_nodetree)
Another change is that objects with shader errors now appear solid magenta instead
of shaded magenta. This is only because of code reuse purpose but could be changed
if really needed.

We implement cubemap array support for EEVEE's lightcache reflection probes.
This removes stretched texels and bottom hemisphere seams artifacts caused
by the octahedral projection previously used.
This introduce versioning code for the lightcache which will discard any
lightcache version that is not compatible.

The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
When using Material Previews not all uniform blocks were filled. This
patch will add the renderpass_block when drawing the background.
Note that I wasn't able to reproduce the issue on my system, but
according the the backtrace it most likely solves the issue. I let the
reporter test.
This is using the GGX probe as background. This has the drawback of
having the resolution choosed in the indirect lighting setting.
The blurring is not really high-quality.
The pros is that it has a simple implementation and is fast to evaluate.
This patch also fades the background alpha to make overlay engine draw the
default background color in the correct color space. Removing one colorspace
hack.

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.
When using LookDev in Quad view the cache was only updated for the first
Q-view. The evaluation data of the last cache was not stored with the
lightprobe textures. As the evaluation data was reused between the
Q-views only the lightprobe textures of the first view was updated.
With this patch the evaluated data is stored amongside the actual
lightprobe textures.

This was due to environement not being rendered with alpha blending. So
color was still written and contributed to the final render color. Now
we multiply by background alpha so that it removes any background pixels
intensity.
For this reason this made the (incorrect) final premult unecessary.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

TH_BACK was being used when drawing the 3D view even though
there was no way to set the color in the preferences.
The color was zero'd when moving to the new 2.8x theme.
Having both gradient and background colors was confusing,
especially having to use 'TH_HIGH_GRAD' for the 3D view, 'TH_BACK' for
other views.
Move the background color back to 'TH_BACK', 'TH_BACK_GRAD' is used
when gradients are enabled.
RNA is unchanged so presets don't need updating.
This changes a bit how the userprefs solid lights works. They are not
visible until enabling the "Edit Solid Light" checkbox. Once enabled the
current studiolight used for solid mode will be overwritten.
Once the lighting settings are tweaked, the user can click the
"Save as Studio light" button to save the current settings.
This makes it easy to create new lighting without messing the other
presets.
The studio lights are stored as ASCII files on the disk using a dead
simple custom format.
The UI/UX is not perfect and will be improved in other commits.
Also includes:
* Separate LookDev HDRI selection from Solid Lights
* Hide LookDev HDRIs from the Solid Lights selection list
* Less Lengthy enum/macro names.
* Optimize computation of Spherical Harmonics.
* Reduce radiance cubemap size a bit. Higher resolution is not necessary.
* Remove STUDIOLIGHT_LIGHT_DIRECTION_CALCULATED (was not used).
* Do windowing on each component separately instead of using luminance.
* Use ITER_PIXELS to iterate on each pixels, using pixel center coords.
* Remove gpu_matcap_3components as it is only needed when creating the gputex.
* Fix a lot of confusion in axis denomination/swizzle.
These changes should not affect functionallity.
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.
Some of them are unecessary and should be removed from the shader instead.
But for now we need a quick fix for the crashes happening on some platforms.
See T55475.
This separate probe rendering from viewport rendering, making possible to
run the baking in another thread (non blocking and faster).
The baked lighting is saved in the blend file. Nothing needs to be
recomputed on load.
There is a few missing bits / bugs:
- Cache cannot be saved to disk as a separate file, it is saved in the DNA
for now making file larger and memory usage higher.
- Auto update only cubemaps does update the grids (bug).
- Probes cannot be updated individually (considered as dynamic).
- Light Cache cannot be (re)generated during render.
Now we light with just a user defined HDRI by default, which is useful
for material setup and texture painting and lighting without having to
set up any scene lights.
Previously it would use the scene world without lights by default, which
in some files is just black.
