It is not practical to change the alpha of the paint color with the
color picker as with the current brush design alpha is the main strength
control for the brush.

There were two issues.
First is related on ISPC's CMake configuration forcing C and C++
compilers to be clang and clang++. This goes against of desired
behavior when we use our own compiled clang compilers.
The second issue was related on linker failure: CLang libraries
are linked statically, and they need some of C++ 11 STL symbols
which are coming from libstdc++.

I'm not sure if the Sky was deliberately left out or was just waiting for a
better moment, but so many I was disappointed that Sky in EEVEE is
completely white.
There are already 2 implementations (osl and gpu) so this is the third one.
Looking at other cases it seems that we are not supposed to share sources
between cycles and the rest? So the new util_sky_model files are just
copies of what is already in cycles, except that the data file uses the RGB
variant of the Hosek/Wilkie model, because we output RGB anyway (but can be
easily changed to XYZ if desired - the results are nearly identical).
I am not sure if it is okay to pass 3*9 float values as 3 mat4 uniforms (I
wanted to use mat3 but it does not work).
Also, should I cache the sky model data between renders if the parameters
do not change?

Every Particle Simulation node has a name (or a path when it is in a node group).
This name has to be used in the Simulation modifier on a point cloud to see
the particles.
Caching has been disabled for now, because it was holding back development
a bit. To reset the simulation, go back to frame 1.
Currently, there is no way to influence the simulation. There are just some
randomly moving points. Changing that is the next step.
Duplication and deletion code of modifiers was totally wrong for
particle system, that special weird thing needs its own custom
management.
Note that for now I chose not to duplicate the particle settings ID when
duplicating the modifier...
This adds support for path selection for vertex edge & face selection
modes, matching mesh editing behavior, useful with the UV rip tool.
Region select & edge tagging are currently not supported,
although they could be added eventually.
This uses the new implicit conversions and constructors
that have been committed in the previous commit.
I tested these changes on Linux with gcc and on Windows.
This allows us to avoid many calls to `as_span()` methods. I will
remove those in the next commit. Furthermore, constructors
of Vector and Array can convert from one type to another now.

The ff_cfhd_init_vlcs() function was using a lot of stack space, which
made linker on macOS unhappy. Using heap allocation allows to silence
the warning without causing other side-effects.
Kept the patch enabled for all platforms to avoid difference in behavior
and performance on different platforms, which could make certain types
of investigation very tricky.

This was the last of the three network optimizations I developed in
the functions branch. Common subnetwork elimination and constant
folding together can get rid of most unnecessary nodes.
This can be used to find separate islands in meshes efficiently (as is
done in cycles already). Furthermore, this helps to implement some
algorithms on node trees more efficiently.
C++17 does not work on 10.12, and Apple extended support ended for 10.12 in
October 2019.

Those optimizations work on the multi-function network level.
Not only will they make the network evaluation faster, but they also
simplify the network a lot. That makes it easier to understand the
exported dot graph.
This can be useful to save the result of a cloth simulation as a
shape key without destroying the simulation, so it's possible to
e.g. re-run it to get other shapes, or simply use the new shape
key to start the simulation already in a draped state.
It also makes sense to allow applying as shape key even when the
mesh is shared, because the operation itself just adds a shape
key. To support this, split the apply operator into Apply and
Apply As Shapekey so that they can have different poll callbacks.

The problem here was numerical precision: The code calculates the angle between
sun and view direction, and the usual acos(dot(a, b)) approach for that has
poor numerical performance for almost parallel angles.
As a result, the generally tiny difference between floating point computation
between CPU and GPU was enough to make the sun vanish at different radii,
causing different results.
The new version fixes the difference by making the computation much more robust
on both platforms.
This adds new callbacks to `bNodeSocketType` and `bNodeType`.
Those are used to generate a multi-function network from a node
tree. Later, this network is evaluated on e.g. particle data.
