This updated set of Mantaflow files includes the improved OpenVDB file IO. With this update it is finally possible to store multiple grids per file. It is also possible to save particle systems and particle data to OpenVDB files.
Draco sets CMAKE_CXX_STANDARD to 14, given we
set the c++ standard in the root level CMakeLists.txt
to c++17 this generated build warnings.
Given the rootlevel one is the one we want we can
safely remove this line in dracos cmakelists
Using latest master because of various compilation error fixes.
Brings a lot of recent development. From most interesting parts:
- New threading model.
- Tiny solver.
- Compatibility with C++17.
- Changing API for time values from float to double for better precision.
- Fixing minor mistakes in the documentation.
- Fixing minor unnecessary large memory allocation.
Bullet currently generates the majority of the warnings
on windows all of them are silly. This patch disables
all warns from bullet for now.
We should revisit this if/when we update bullet
to a newer version.

`google::LogMessageFatal::~LogMessageFatal` calls `abort`
which MSVC correctly identifies as 'not returning'
and warns about a potential memory leak.
Given this is intended behaviour and glog is not overly
concerned with shutting down the process nicely, we
can safely ignore this warning.
Updates include:
- std::move() cleanup in rcmatrix.h
- Enabled parallelization for fluid guiding (fairly noticeable speed improvement).
- More flexible flags setter function with control over boundary width.
- Fixed uninitialized result used in DynamicMusic::seek().
The comment to this function says false is returned if the handle
is invalid, while in practice non-initialized value will be returned.
- Spelling typos in comment.
- Silence -Wdelete-non-abstract-non-virtual-dtor warning.

Updates include:
- A fix from Jacques that changed the loop order in the mesh creation function (the fix speeds up the function significantly due to fewer cache misses).
- Some of the grid copy helper functions are now multithreaded.
- A fix for Windows file IO. Now it possible to load files with non ASCII characters on Windows too.
This modifies the common CUDA implementation for adaptive kernel compilation slightly to support both CUBIN and PTX output (the latter which is then used in the OptiX device). It also fixes adaptive kernel compilation on Windows.

MSVC has a conformance mode (/permissive-) where the C++ standard is more strictly
enforced. This mode is available on MSVC 15.5+ [1]
This patch enables this mode on compilers that support it and cleans up the few violations it threw up in the process.
- Mantaflow was using M_PI without requesting them using the _USE_MATH_DEFINES define to opt in to non default behaviour.
- Collada did not include the right header for std::cerr, this seemingly was fixed for other platforms already but put inside a platform guard.
- Ghost had some scoping issues regarding uninitialized variables and goto behaviour
Second landing of this patch, earlier commit was reverted due to some compiler configurations having slipped though testing

It is breaking compilation on some configurations, revert for now while
i see what is wrong.
This reverts commit 9fe469c110940af5d2525158305d5d365bd15276.

Glew.obj is one of the more expensive targets we have to build clocking in
at 34.907 seconds.
The root cause [1] is the msvc inliner is not super thrilled with the
glewIsSupported supported function, this patch changes the buildflags
of extern_glew to optimize for size rather than speed.
Given glew is only in play at initalization time there will be no
performance impact.
Time to build glew.obj
Before: 34.907s
After : 1.961s
