Scaling of forces needs more work. Before making changes to them it would be nice to have a setup, that works physically correct across multiple modifiers (cloth, rigid bodies, fluid).
This will be a to do for 2.92.
Coalescing on macOS overwrites a singular unprocessed mouse event. To
receive all mouse and tablet events coalescing is disabled.
Disabling coalescing for macOS disables coalescing for trackpad
gestures. Repeat trackpad events are unnecessary and found to
negatively impact performance thus are re-coalesced in Window Manager.

The OpenVDB data structure can store voxel data in leaf nodes or tiles
when all the nodes in a given region have a constant value. However,
Cycles is using the leaf nodes to generate the acceleration structure
for computing volume intersections which did not include constant tiles.
To fix this, we simply voxelize all the active tiles prior to generating
the volume bounding mesh. As we are using a MaskGrid, this will not
allocate actual voxel buffers for each leaf, so the memory usage will be
kept low.

Now that the Blender sync mechanism deletes nodes from the scene, we need to
ensure scene update is stopped before we do this.
Also add some more early out in scene geometry update to ensure we do not
continue working on incomplete geometry data, though that was not the cause of
this crash.
Two issues:
* Automatic deduplication of OpenVDB grid data was failing when Cycles had
already cleared the OpenVDB grid, causing an empty grid. Instead rely on
Blender return the same OpenVDB grid pointer when deduplication is possible.
* The volume bounds mesh was not properly cleared when the OpenVDB grid was
empty, causing a mismatch between mesh and voxel data.
The names of the parameters are based on those of those of the sockets, so they also need to be updated. This was forgotten about in the previous commit (rBa284e559b90e).
Ref T82561.
There were some changes to the NanoVDB API that broke the way Cycles was previously using it.
With these changes it compiles successfully again and also still compiles with the NanoVDB revision
that is currently part of the Blender dependencies. Ref T81454.
The "type" sockets on shader nodes were renamed in rB31a620b9420cab to
avoid clashes with the `NodeType type` member from the Node base class,
but the OSL shader compilation was missing those changes.
Expand unit test for `BKE_fcurve_active_keyframe_index()` to test edge
cases better.
This also introduces a new test macro `EXPECT_BLI_ASSERT()`, which can be
used to test that an assertion fails successfully.
No functional changes to actual Blender code.
Previous code was flipping the bits on a 32-bit number and doing a zero extension to cast to 64-bit, so mark the constant as long to begin with.
This would also erase previously set bits in this part the flag.
forceinline attribute is only applicable for function which are
marked inline. Interestingly, it can be used for class methods
without explicit inline statement. But for functions it is another
story.
And remove Blender preference, which was expected to be set to match the system
preference for correct behavior. Instead just handle this automatically.

Volumes using tricubic sampling were producing different results with NanoVDB compared
to dense textures. This fixes that by using the same tricubic sampling algorithm in both
cases. It also fixes some remaining offset issues and some minor things that broke OpenCL
kernel compilation on NVIDIA.

Use bool return type where possible instead of int (the return values from fluid object are already boolean instead of int).
Also removed several if guards in API functions. If one of the arguments is in fact invalid / nullptr (should not happen though), it better to catch them directly where they failed and not silently escape them.
This commit corrects the maximum resolution field in Fluid objects. The field should be set to the maximum possible resolution, i.e. it should not adjust with adaptive domains and stay constant all the time.
The reason for this is that this resolution value will be used to scale gravity. And this gravity should be constant for adaptive domains too.
It remains to be shown if this issue was the only reason for line-artifacts as seen in T74559.
