* 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.
This makes previewing thick smoke a bit more plausible with better shadows.
The shadowing is clamped so that nothing is completely black. That said the
lower bound is pretty low.
This is not an option but could become one if users do not like it in
all situations.
The appearance is a bit different than 2.79 where the flame was just added
on top of the smoke without correct blending.
Now it's much more realistic and using volumetric integration. You can see
the smoke actually masking the flame.
The other difference is that the flame color was not using proper color
managed blending. Now with the use of filmic it shows bright yellow.
This could be adjusted and displayed as a user parameter in the future.
Includes the following fixes
- Fix smoke texture creation: data was interpreted as Byte instead of Floats.
- Fix Velocity texture not being free after draw: also was causing crashes.
- Fix display_thickness not being copied during COW.
- Fix Blending and general volume rendering algorithm.
- Add Volume Shadowing support.
This commit make the Xray option for the wireframe different from the other
shading mode. This makes it possible to rapidly switch between wireframe +
Xray and Solid mode without Xray.
Xray alpha is also decoupled.
Both variables are duplicated and exposed separately through RNA.
This is using the existing engine (workbench forward) with 0.0 xray_alpha
and forcing wireframes on all objects.
There is no workflow/shortcut changes in this commit.
This make the workbench draw everything in the background routine just like
eevee. This is because the workbench uses floating point buffers too and
rendering background to this buffer makes it incorrect without proper
color management.
This could be improved because in xray the background is not blended but
dithered as it's drawn after the main pass.
OpenGL rendering only implemented the deferred renderer. This commit
will add the forward renderer. The forward renderer is used when XRay
mode is enabled
Usage of matcap image uniform had different ifdef than definition
of that uniform. Assuming the usage was correct, and the definition
needed an update.
Prevents shader from compilation failure and from aborts in debug
builds.
This ignores the scene color managment view settings for solid mode and
lookdev when not using scene lights and world. The scene settings are
intended for tweaking renders and should not affect studio lighting and
matcaps.
There may be cases where a simple sRGB transform is better than Filmic
and we could add configuration for this. Not sure if it really matters
and it may be better if we just assume matcaps and studiolights are all
created for one view transform.

Replaced the draw world option with a shading.background_type enum.
Where the user can select Theme, World or a Custom color.
World and theme colors do not always work in workbench. We needed to
have an option what the user could control locally (per viewport).
Especially when using linked data.
I removed the world background drawing from the draw_manager. It was never used as EEVEE and Workbench both override the logic.
Not 100% sure about the naming of Theme, World, Viewport.
In other parts of blender's codebase World is sometimes called Scene.
Will stick to the names that describes its location best.

For some reason 32c5972653 broke display of
solid meshes in workbench.
After some investigation, it seems that the vertex coordinate output is
degenerated even if the input is correct and the matrix too.
Removing dead code seems to fix the problem. So maybe the GLSL preprocessor
is not doing what it should?
