Sergey Sharybin bbfc97ad6f Move tests/data and assets to the main repository
This change moves the tests data files and publish folder of assets
repository to the main blender.git repository as LFS files.

The goal of this change is to eliminate toil of modifying tests,
cherry-picking changes to LFS branches, adding tests as part of a
PR which brings new features or fixes.

More detailed explanation and conversation can be found in the
design task.

The bones are named Top, Middle, and Bottom for simplicity.
All bones are selected, multi-paint is active,
but the bone combinations are covered at the different edge loops.
To do the test, paint over the vertices that are in the top ortho view
with the provided Add brush (weight and strength 1.0)
For the first, highest set of vertices,
you should be able to sample these weights from each different bone
(Ctrl+LMB with the corresponding bone selected):
Top weight: 1.000
Middle Weight: 0.667
Bottom weight: 0.333
The second ring down will have
Top weight: 1.000
Middle Weight: 0.667
Bottom weight: 0.000
The third ring will have
Top weight: 1.000
Middle Weight: 0.000
Bottom weight: 0.333
And the fourth and final ring will have
Top weight: 0.000
Middle Weight: 1.000
Bottom weight: 0.500
For the next case, enable auto normalize.
You can switch to the bottom ortho view for an unaltered set of vertices,
but it will not change the final results.
Make sure all of the bones are selected.
Paint over the vertices in the view with the same Add brush as before.
The first, top ring will have:
Top weight: 0.5
Middle Weight: 0.333
Bottom weight: 0.167
The second ring down will have
Top weight: 0.600
Middle Weight: 0.400
Bottom weight: 0.000
The third ring will have
Top weight: 0.750
Middle Weight: 0.000
Bottom weight: 0.250
And the fourth and final ring will have
Top weight: 0.000
Middle Weight: 0.667
Bottom weight: 0.333
For any case:
Weights of zero should always remain zero.
Having only one bone selected should behave like a regular paint.
