Regression from rB2dba2b3d71d9781bce45. Do not understand why MSVC needs this convoluted
allocation (looks like broken compiler crap?), but at least let's do it correctly!
Unfortunately this doesn't make all tests compilable due
to all sort of weird and wonderful bad levels includes
on Windows (G referenced from bf_blenlib) but at least
allows to selectively build tests for now.
While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

mat3_polar_decompose gives the right polar decomposition of given matrix,
as a pair (U, P) of matrices.
interp_m3_m3m3 uses that polar decomposition to perform a correct matrix interpolation,
even with non-uniformly scaled ones (where blend_m3_m3m3 would fail).
interp_m4_m4m4 just adds translation interpolation to the _m3 variant.
Extensions such as ".tar.gz" are now also supported. Before this patch,
ensure_ext('demo.tar.gz', '.tar.gz') would return 'demo.tar.tar.gz'.
This results in issues with the `ExportHelper` mix-in class; clicking
an existing file in the file dialogue warns about overwriting it
(highlighting the input box in red), but then saves to a different
file.
Also added a unit test for the new behaviour.

This commit:
* Adds a 'compare_ff' function for absolute 'almost equal' comparison of floats.
* Makes 'compare_vxvx' functions use that new 'compare_ff' one.
* Adds a 'compare_ff_relative' function for secured ulp-based relative comparison of floats.
* Adds matching 'compare_vxvx_relative' functions.
* Adds some basic tests for compare_ff_relative.
See https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/
Note that we could replace our python/mathutils' EXPP_FloatsAreEqual() by BLI's compare_ff_relative
(using a very small absolute max_diff), but these do not have exact same behavior...
Left a comment there for now, we can do it later if/when we are sure it won't break anything!
Performance tests now have their own CMake macro, which ensures they do not get
added to ctest list, so we do not have to bother about them anymore, and can always
build them (when GTests are enabled, of course).
Alternative to T32894, simple test which creates new data and compares with RNA defaults.
Can be used to keep the values in sync without having to maintain a large set of defines.
We could likely add much more, but those already covers basic behavior and should be able
to catch most errors when editing this code.
Also added some performances tests as well (timing ghash insert/lookup under heavy loads,
for different kinds of keys).
Added conversion to and from exponential map representation. This
representation is useful for interpolation of > 2 quaternions, or in
PD controllers.
Implementation in C functions quat_to_expmap,
quat_normalized_to_expmap, and expmap_to_quat with Python API, unit
tests and documentation.
Added Quaternion.to_exponential_map() and Quaternion(3-vector) to
Python API.

This reverts commit d390e24c49ba8543b56948402622563cae6e860f.
Forcing tests to success is really bad idea. It'll only lead to cases when
you see PASSED and will think everything is OK.
Long story short: never force tests to pass!
Recent addons commit meant that addons would be enabled even if they weren't found.
This would give an error (which is fine), but also remove from preferences.
The idea is to use the set of really small images from the lib folder
and run Cycles render on them comparing render output to reference
images in the tests repository.
For sure same thing could become more generic for BI or Freestyle
render engines.
Thanks Campbell for review and code tweaks!
Too many contrib addons are in an unstable state making the test not so useful.
Thanks to Sergey initial patch: D1012, redid mostly - but outcome is the same.
`BLI_strncpy_ensure_pad()` is also useful with current master code.
The two others (`BLI_strcmp_ignore_pad()` and `BLI_filelist_duplicate()`)
are only used in asset branch currently, but think they could be useful
in other places too, and simplifies handling of asset branch & future patch review.

Main purpose of this is to bring new gflags library which is more likely
to have a fix for undefined order of static variables initialization and
also to bring new glog where some compilation error are fixed (which are
only visible with more strict checks with clang and c++11 enabled).
Murmur2a is a very fast hashing function generation int32 hashes.
It also features a very good distribution of generated hashes.
However, it is not endianness-agnostic, meaning it will usually generate
different hashes for a same key on big- and little-endian architectures.
Consequently, **it shall not be used to generate persistent hashes**
(never store them in .blend file e.g.).
This implementation supports incremental hashing, and is a direct
adaptation of reference implementation (in c++):
https://smhasher.googlecode.com/svn-history/r130/trunk/MurmurHash2.cpp
That cpp code was also used to generate reference values in gtests file.

Collection of test cases from libGDX and our own tracker
Tests:
- combine triangle area matches polygon area.
- tris have same winding.
- tris don't have duplicates.
- correct number of internal & boundary edges.
- degenerate polys still give topologically correct output.
also checks all possible start-vert offsets, forwards and backwards.
optional OBJ output, for debugging.
Those two mimic our BLI invert_m4_m4_safe - they add a small offset to diagonal values,
in case org matrix is degenerated, and if still non-invertible, return identity matrix.
Org patch by me, final enhanced version by ideasman42, many thanks!
Now always check for a default unit, and evaluate the whole expression in this "unit space".
Not an ideal solution, but should handle most cases nicely
(we can't address all possible corner cases anyway).
Note default unit is searched in current string first (bigger unit of current system wins),
then in previous string.
Note this also replaces ',' by '+' in default separation between units,
helps solving issues with parenthesis (e.g. (1'1")*2.5 would fail in existing code)!
This would break if someone uses py ops with lower precedence than '+' (like bitwise
operations, and comparison), but these are not expected usecase here anyway.

- add BLI_stack_count
- add BLI_stack_pop_n to pop into an array
- add BLI_stack_push_r, which returns a pointer that can be filled in
Also remove sanity check in BLI_stack_pop, assert if the stack is empty.
Needed to make the blender link libraries a global property
now that tests are parallel to source directory.
Current sort order for blender link libraries doesn't work
for tests that start with few defined symbols. Doubling the
lib list works, but a TODO to find a better way (probably
using CMake's own mechanism for tracking dependencies).
