Use orig_pchan when searching for the original copy of a constraint.

Fix box select of edges not working when box does not fully contain edge.

Addons: enable GLTF 2.0 addon by default.

Merge branch 'master' into blender2.8

Fix T58006: smart UV project island margin should not use length units.

This distance is in UV space, not world space.

Sequencer: remove unnecessary limit on transform rotation.

Fix X11 tablet pen and eraser distinction being wrong in some cases.

This extends the earlier fix to use the latest logic from Wine's wintab.c,
to better handle eraser detection.

Merge branch 'master' into blender2.8

Cleanup: remove unused file

Merge branch 'master' into blender2.8

Cleanup: trailing space

Fix T56374, T57066, T58037: crash on startup on macOS when using translation.

Fix random color drawing having similar colors for similar names.

Fix T58022: Changing workspace may change layout of User Pref window

Logic to update child windows on workspace changes should simply ignore
temporary child windows. Users opened those for a specific purpose (i.e. edit
user preferences or show render result). Blender should not come in and
repurpose it.

Fix penpressure for tablets that use libinput on linux

refactor: Collada reorganize class constructors

- Class constructors without body (only attribute initialisations)
can safely be kept in the class header files

- Constructor variables should be initialized in the order of their
definition in the header files

This change is also aimed to remove a couple of
build warnings from the linux builds.

Keymap: preference for extended shading menu

This brings back the option to have x-ray & overlay toggle.

Depsgraph: add a new operation node for computing B-Bone segments.

Computing the shape of a B-Bone is a quite expensive operation, and
there are multiple constraints that can access this information in
a variety of useful ways. This means computing the shape once per
bone and saving it is good for performance.

Since the shape may depend on the position of up to two other bones,
often in a "cyclic" manner, this computation has to be a separate
node with its own dependencies.
