Refactor and improve waveform drawing.
Drawing now can use line strips to draw waveforms instead of only
triangle strips. This makes us able to properly visualize thin waveforms
as they would not be visible before. We now also draw the RMS value of
the waveform.
The waveform drawing is now also properly aligned to the screen pixels
to avoid flickering when transforming the strip.

The duration and start time for audio strips were not correctly read in
audaspace.
Some video files have a "lead in" section of audio that plays before the
video starts playing back. Before this patch, we would play this lead in
audio at the same time as the video started and thus the audio would not
be in sync anymore.
Now the lead in audio is cut off and the duration should be correctly
calculated with this in mind.
If the audio starts after the video, the audio strip is shifted to
account for this, but it will also lead to cut off audio which might not
be wanted. However we don't have a simple way to solve this at this
point.

(Some minor changes done in the patch)
Contributed by @erik85 in D11400. The idea from this patch was placed in
a more generic context: A new FOR macro has been added that loops
over the neighbors of a cell within a given radius.
Includes update for OpenVDB file IO, i.e. fixes an issue with
compression flag combination that resulted in random segfaults.
Other changes: Cleanup and formatting.
This is an implementation of Enhanced Subpixel Morphological Antialiasing (SMAA)
The algorithm was proposed by:
Jorge Jimenez, Jose I. Echevarria, Tiago Sousa, Diego Gutierrez
This node provides only SMAA 1x mode, so the operation will be done with no spatial
multisampling nor temporal supersampling. See Patch for comparisons.
The existing AA operation seems to be used only for binary images by some other nodes.
Using SMAA for binary images needs no important parameter such as "threshold", so we
perhaps can switch the operation to SMAA, though that changes existing behavior.
Notes:
1. The program code assumes the screen coordinates are DirectX style that the
vertical direction is upside-down, so "top" and "bottom" actually represent bottom
and top, respectively.
Thanks for Habib Gahbiche (zazizizou) to polish and finalize this patch.

All headers in the svn libraries should be
building with /W0 however MSVC 16.8/16.9
has broken this functionality making OpenVDB
emit lots of warnings.
The breakage was reported [1] in august to MS
but they still have not gotten around to
addressing the issue.
This change explicitly suppresses C4251 in the
module that emitted these warnings. As the warning
is useful in other parts of blender a localized
approach is taken rather than a global suppression.

* USD and OpenVDB headers use deprecated TBB headers, suppress all deprecation
warnings there since we have no control over them.
* For our own TBB includes, use the individual headers rather than the tbb.h that
includes everything to avoid warnings, rather than suppressing all.
This is in anticipation of the TBB 2020 upgrade in D10359. Ref D10361.
This updates fixes the following issues (critical for 2.92):
- Issue that prevented dense 'int' grids from being exported (incorrect clip value)
- Issue with particles outside out of domain bounds (position between -1 and 0) not being deleted
Includes improvements for the file IO. Namely, more meta data will be written from now on.
This change is required to prevent IO issues (e.g. T84649) that arised through the use of sparse grids caching (introduced in 2.92).
The issue was that sounds were always faded from 0 volume when they
started and depending on the currently used buffer size, the fading took
longer or shorter.
The solution stores whether the sound has ever been played back and
consequently does not fade when starting to play back.
Mainly updated the Mantaflow version. It includes the new viscosity solver plugin based on the method from 'Accurate Viscous Free Surfaces for Buckling, Coiling, and Rotating Liquids' (Batty & Bridson).
In the UI, this update adds a new 'Viscosity' section to the fluid modifier UI (liquid domains only). For now, there is a single 'strength' value to control the viscosity of liquids.
Issues were:
* Abusing of `WITH_PYTHON_INSTALL_NUMPY` by both Audaspace and
Mantaflow.
- `PYTHON_INSTALL` options only decide whether we copy python (and
some extra modules) in our Blender installation. On linux it
makes much more sense to use global python installation.
- Now we have instead a proper `WITH_PYTHON_NUMPY`
* Bad assumptions regarding path of headers relative to path of python
module.
- In current Debian testing, modules are under `python3.9`
directory, while headers are under `python3` directory.
- Now we properly `find_path` for headers as well, modifying
`find_python_package` to take an optional argument for headers.
Note that the required changes done to `extern` libraries are in
blender-specific files that do not exist upstream.

This update introduces two improvements from the Mantaflow repository:
(1) Improved particle sampling:
- Liquid and secondary particles are sampled more predictably. With all parameters being equal, baked particles will be computed at the exact same position during every bake.
- Before, this was not guaranteed.
(2) Sparse grid caching:
- While saving grid data to disk, grids will from now on be saved in a sparse structure whenever possible (e.g. density, flame but not levelsets).
- With the sparse optimization grid cells with a value under the 'Empty Space' value (already present in domain settings) will not be cached.
- The main benefits of this optimization are: Smaller cache sizes and faster playback of simulation data in the viewport.
- This optimization works 'out-of-the-box'. There is no option in the UI to enable it.
- For now, only smoke simulation grids will take advantage of this optimization.
We already were using one of earlier RC of the library, so there is no
expected big changes. Just making the update official, using official
version and stating it in the readme file.
