Face Sets where only set and updated on the PBVH after starting a sculpt
tool. In order to preserve the visibility they store when changing
levels, they need to be updated and sync also on PBVH creation

The problem in this case was that the flag for active fire was not set. With hidden flow sources the flag was not updated in update_flowsflags().
The solution for this is to take the active field from the config cache file.
Same exact system as instancing on vertices for a mesh. More powerful ways
of instancing will be added at some later point, but this makes the basics
works and is consistent with other geometry types.
Before: If the current frame is out of the cache start/end range, the viewport will show the fluid as it was on the last frame that was still in the cache frame range.
Now: If the current frame is out of the cache start/end range, the viewport will show no fluid at all (even if there are cache files present for this frame).
This fix is related / in response to T79423.
Instead of clearing forces at the end of the simulation step, they will now be cleared before writing to them, i.e. at the beginning of a step.
Also cleaned up minor areas that I looked at while making this change.
Following work done in 2.83, the resolution control is now a real
level-of-detail parameter. It is now useful to be able to set the
resolution for display independently from render. This is true for
both mesh generation and mesh deformation modes.
For compatibility with old scenes, resolution is retained and is the
render resolution. Old modifiers loaded have the value of resolution
also applied to viewport resolution. This allows newer modifiers to
be used in older versions without trouble

This patch adds the ability to render motion blur from Alembic caches.
The motion blur data is derived from a velocity attribute whose name has
to be defined by the user through the MeshSequenceCache modifier, with a
default value of ".velocities", which is the standard name in Alembic
for the velocity property, although other software may ignore it and
write velocity with their own naming convention (e.g. "v" in Houdini).
Furthermore, a property was added to define how the velocity vectors
are interpreted with regard to time : frame or second. "Frame"
means that the velocity is already scaled by the time step and we do not
need to modify it for it to look proper. "Second" means that the unit
the velocity was measured in is in seconds and so has to be scaled by
some time step computed here as being the time between two frames (1 /
FPS, which would be typical for a simulation). This appears to be
common, and is the default behavior.
Another property was added to control the scale of the velocity to
further modify the look of the motion blur.

The hardcoded age limit is now gone. The behavior can be implemented
with an Age Reached Event and Kill Particle node. Other utility nodes
to handle age limits of particles can be added later. Adding an
Age Limit attribute to particles on birth will be useful for some effects,
e.g. when you want to control the color or size of a particle over its
life time.
The Random Float node takes a seed currently. Different nodes will
produce different values even with the same seed. However, the same
node will generate the same random number for the same seed every
time. The "Hash" of a particle can be used as seed. Later, we'd want
to have more modes in the node to make it more user friendly.
Modes could be: Per Particle, Per Time, Per Particle Per Time,
Per Node Instance, ...
Also a Random Vector node will be useful, as it currently has to be
build using three Random Float nodes.

The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
Yet another update to ensure that pointer variables are always up to date, i.e. those referencing the memory allocated by Mantaflow. Outdated pointers usually show up through flickering in viewport.
In f2b04302cd the pointer update was refactored. It was sufficient to update pointers just in replay mode at the end of a step since the 'ensure()' functions from manta_fluid_API.cpp had their own pointer update call. These were removed in 51f4bee5a5, however, and so in order to still have some sort of update, the given update call needs to be available to all cache types.
A collection of multiple changes that had been living in my stash:
- Use nullptr instead of NULL in C++ files
- Removed unused/deprecated functions from headers
- Cleared animatable flag in cache UI
- Comment cleanups
Use static_cast() where possible and refresh pointers for every frame when in replay mode. The latter is particularly important as this seems to have caused the issue where smoke in the viewport was flickering when loading data from pointers after loading them from disk for the frame before (e.g. when resuming a bake job).
This is the first step for having sequences covered with session UUID
with the goal to remove code which uses original sequence pointer to
match sequences.
Currently this UUID is maintained on file load, allocation and leaf
duplication function.There are more cases to cover and ensure UUID
is re-generated or re-used when needed. It will be done as follow-up
development.
This patch adds a new compound shape entry to the shape selection
dropdown. It also corrects wrong inertia calculation for convex hulls,
that resulted in strange behavior for small objects.
The compound shape take the collision shapes from its object children
and combines them. This makes it possible to create concave shapes from
primitive shapes. Using this instead of the mesh collision shape is
often many times faster.

This is in order to disolve GPU_draw.h into more meaningful code blocks.
All the Image related function are in `image_gpu.c`.
All the MovieClip related function are in `movieclip.c`.
The IMB module now has a connection with GPU. This is not strickly
necessary and the code could be move to `image_gpu.c` if needed.
The Image garbage collection is also ported to `image_gpu.c`.
This uses mesh's runtime mutex for both `BKE_mesh_runtime_looptri_ensure`
(was using its own global RW mutex before), and `BKE_mesh_wrapper_ensure_mdata`
(was not protected at all before).
This is more like a band-aid than a proper fix, as mentioned in the report
proper fix would be for the modifier to request those data (the relevant
BVHTree, which would implicitely also call the tow others) through flags,
just like it does for regular CDData layers. But this is a much bigger
refactor to be done outside of bugfix scope.
