Triangulating ngons could fail with the method that was being
used: projecting along the dominant normal axis and then using CDT.
It could fail if the ngon has self crossings or might be so after
the described projection.
Switched to using projection along the normal itself, and also to
using polyfill which produces some kind of triangulation no matter
what in such circumstances. This will also likely be faster if
there are a lot of ngons in the meshes, since the exact arithmetic
CDT was being used before, and now float arithmetic is used.
This was caused by the window_translate_m4 not offsetting the winmat in the
right direction for perspective view. Thus leading to incorrect weights.
The workbench sample weight computation was also inverted.
This fix will change the sampling pattern for EEVEE too (it will just
mirror it in perspective view).
Using `FunctionRef` is better than using `std::function`, templates and c function
pointers in some cases. The trade offs are explained in more detail in code documentation.
The following are some of the main benefits of using `FunctionRef`:
* It is convenient to use with all kinds of callables.
* It is cheaper to construct, copy and (possibly) call compared to `std::function`.
* Functions taking a `FunctionRef` as parameter don't need to be declared
in header files (as is necessary when using templates usually).

The Exact modifier code had been written to avoid using BMesh but
in the initial release the modifier still converted all Meshes to
BMeshes, and then after running the boolean code on the BMeshes,
converted the result back to a Mesh.
This change skips that. Most of the work here is in getting the
Custom Data layers right. The approach taken is to merge default
layers from all operand meshes into the final result, and then
use the original verts, edges, polys, and loops to copy or interpolate
the appropriate custom data layers from all operands into the result.
Previously, methods like `Span.drop_front` would crash when more
elements would be dropped than are available. While this is most
efficient, it is not very practical in some use cases. Also other languages
silently clamp the index, so one can easily write wrong code accidentally.
Now, `Span.drop_front` and similar methods will only crash when n
is negative. Too large values will be clamped down to their maximum
possible value. While this is slightly less efficient, I did not have a case
where this actually mattered yet. If it does matter in the future, we can
add a separate `*_unchecked` method.
This should not change the behavior of existing code.
* WITH_CPU_SSE was renamed to WITH_CPU_SIMD, and now covers both SSE and Neon.
* For macOS sse2neon.h is included as part of the precompiled libraries.
* For Linux it is enabled if the sse2neon.h header file is detected. However
this library does not have official releases and is not shipped with any Linux
distribution, so manual installation and configuration is required to get this
working.

This commit adds a drop-down to the attribute randomize node to support
a few operations on the values of existing attributes: "Replace/Create"
(the existing behavior), "Add", "Subtract", and "Multiply".
At this point, the operations are limited by what is simple to implement.
More could be added in the future, but there isn't a strong use case
for more complex operations anyway, and a second math node can be used.

* 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.
While Boolean is not guaranteed to work if the operands are not
volume-enclosing (technically: PWN - piecewise constant winding number),
it needs to do something in those cases. This change makes
more cases meet user expectations in T84493, T64544, T83403,
T82642 (though very slow on that one).
The original new boolean code used "generalized winding number"
for this fallback; replaced this with code that uses raycasting.
Raycasting would have been faster, but for unfortunately also
switchd to per-triangle tests rather than per-patch tests since
it is possible (e.g., with Suzanne) to have patches that are
both inside and outside the other shape. That can make it much
slower in some cases, sadly.
Resolves modernize-raw-string-literal Clang-Tidy warning
The way warning works is it suggests to use raw literal when
overhead of having escape characters is higher than the overhead
of having raw literal syntax (talking about code size overhead).
This means that the warning will not trigger for "foo\"bar".

This patch fixes a bug introduced in
rB74188e65028d268af887ab2140e4253087410c1e.
The commit incorrectly moved the declaration and intialization of the
variable `pwr` inside the loop. Since the value was originally modified
in each iteration based on it's previous value and `pwHL` through
`pwr *= pwHL`, this change in scope was wrong. It resetted the value in
each iteration. This patch moves the declaration of `pwr` outside the
loop again.

The unused result was reported by Clang-Tidy 11.
It does make sense to check for the failed mmap() calls rather than
quietly suppress errors.
In this change failures are reported, but application execution is
not aborted. This is a bit disputable, but it feels to be a safer
thing to do now.
It is unclear how to test the code though, as we don't have any
tools in-place to simulate read errors.

BLI_strncpy_wchar_from_utf8 made the assumption that
wchar_t is UTF-32 bit regardless of environment, while
this holds true on both mac and linux, on windows
wchar_t is actually actually UTF-16.
This resulted in the upper 16 bits being dropped from
from some string conversions and prevented blender
from starting when installed in a path with unicode
code-points over 0xffff.
There was also a fair bit of code duplication between
BLI_strncpy_wchar_from_utf8 and BLI_str_utf8_as_unicode_and_size
this change essentially removes all logic from
BLI_strncpy_wchar_from_utf8 and calls the right function
for the right environment.

Important lesson to be learned here, leaving comments
is great and in the moment, they usually make sense.
Many months later they may not quite make as much sense
any more and time will have to be spend to figure out
what was meant, all of this would have been averted with a
better comment.
The zero terminator in this case, I can find no evidence
of it being used or relied on at any point. It does however
break GTests's `EXPECT_EXIT` macro that stops looking in
the output as soon as it sees the zts and doesn't end up
looking at the actual assert text being thrown. Which in
turn makes the`fcurve_active_keyframe`test fail when run
in debug mode on windows.
* tbb::blocked_range moved to a different namespace and since the fix is
non-trivial, remove some unused code that used this.
* Task group priorities are no longer supported. It's unclear if they are
useful at all right now and even set correctly, for now all tasks are equal
priority with TBB 2021.
