Fix incorrect object visibility test in baking.

Motion paths: default to bone head instead of tail location.

This puts the motion path in the same location as the transform gizmo,
which is less confusing especially if you have a custom bone shape where
the tail is not visible.

Fix T55958: allow the user to select between spring and spring2.

The old springs with damping 1.0 operate in a special way that
is more similar to plastic deformation than a spring. Some users
rely on that, so let the user choose which implementation to use.
This also restores full backward compatibility with 2.79.

Differential Revision: https://developer.blender.org/D3544

Merge branch 'master' into blender2.8

Cleanup: changes from 2.8

Subsurf: Fix wrong vertices index in vertex data interpolation

Subsurf: Subdivide polygons to the same resolution

Previously it was ptex faces which were subdividing to the same
resolution. This was looking like more details for non-quad faces,
but was also causing discontinuity in the edge where quad touches
non-quad polygon.

Now ptex faces which are coming from non-quad faces are subdivided
at a half of resolution, matching old behavior and solving
discontinuity problem.

Fix compilation issue after merge.

UI: Fix flicker in File Browser header

Move running jobs to the beginning of the row.

Thanks @sergey for reporting

Fix missing header include in previous master merge.

Merge branch 'master' into blender2.8

Note: Moved doversion of VSE strips uniquename to 2.8 versionning area,
and raised accordingly current file subversion, since that bug also
affected previous 2.8 .blend files...

Conflicts:
source/blender/blenkernel/BKE_blender_version.h

Fix assert when loading file with multiple windows opened

... or when loading a file when having more windows opened than the file
itself.

Eevee: Remove Colored volumetric option.

This option is not necessary as it uses as much memory as the mono-chromatic
transmistance.

Fix T55668: Volume Keyframe on Cut-ted Metastrip.

We actually still had cases of Meta strip duplication resulting in
non-unique strip names. Quiet surprising this went unoticed for so long. :(

Fixed that bug, and think it was last one (at least, no other case of
SEQ_DUPE_UNIQUE_NAME usage should be broken, I think...), and raised
subversion and updated doversion to run uniquename check on strips on
all previous fileversions.

Note: will have to do that again when merging in 2.8...

Fix large font drawing blurriness in a better way.

GPU_LINEAR is there for shadow font blurring, the real issue was lack of
rounding for the batch offset.

transform_snap_object: Better bvhtree creation management for editing multiple objects.

- Use the object referenced in `BMEditMesh` as the `ghash` key to save the bvhtrees in cache;
- Create a boundbox around edit_mesh to test the snap before creating bvhtree;
- Save the `edit_mesh`s bvhtree in the mesh bvh_cache;

This is a part of the D3504.

Merge branch 'master' into blender2.8

Fix build for Intel compiler with C++11.

UI: more descriptive tooltip

Fix T55634: Particle Viewport Display affects render visibilty

Changed code to follow master behavior closer: ignore draw-as checks
when particles are evaluating for rendering.
