Explain the Local With Parent coordinate space better.

Just saying "parent transformation added" doesn't really explain
what this coordinate space does. Thus it seems almost nobody used
it and serious bugs like T61981 went unnoticed.

Fix T61981: Local With Parent broken as constraint own space.

Specifically, matrix multiplication order in Local With Parent
to Pose space conversion was wrong, compared with Pose to LWP.

Missed version bump in recent commit

Keymap: toggle context gizmo instead of the tool gizmo

When a tool is activated in many cases the gizmo is needed so toggling
them isn't so useful.

Change behavior to use the active object instead so users who prefer
to enable gizmos in the popover can toggle them.

Also remove duplicate keymap item.

Gizmo: individual toggles for 3D view gizmos

The popover for displaying gizmos now has options for
empty, light & camera gizmos.

Transform toggles are now checkboxes, which has the advantage that it's
more obvious they can be mixed however changing from one to another now
uses 3x clicks instead of a single click-drag action.
We might need a faster way to switch between transform types.

Depsgraph: fix debug print crash on IK constraint without target.

Cleanup: rename 'ObData' to 'Object Data'

Fix T63587: 3D View clipping region crashes

Cleanup: doxy comments

Use doxy references to function and enums,
also correct some names which became out of sync.

Cleanup: move operator constants out of DNA

Also use doxy struct member references.

Gizmo: move transform to a persistent option

Based on feedback from animators, this is useful to keep as a view
option (as in 2.7x).

Now the transform gizmos can be enabled from the popover,
the tools still work for location/scale/rotation.
The transform tool has been removed.

See T63518

Keymap: warn when running poll on empty keymaps

Fix T62048: crash when turning off curve path animation with Spline IK.

Both fix missing depsgraph flag, and gracefully give up on missing data.

Fix T37500: implement Bendy bone segment deformation interpolation.

Previously B-Bone deformation mapped every vertex to just one
B-Bone segment. This results in abrupt transformation differences
between the sides of each threshold plane, reducing the quality
of B-Bone deformation and making the use of shape keys impractical.

This commit replaces this approach with a linear blend between
the two closest segment transformations, effectively representing
the B-Bone as two weight-blended plain bones for each vertex.

In order to distribute the interpolation more evenly along the
bone, segment matrices for deformation are now computed at points
between the segments and at the ends of the B-Bone. The computation
also uses the true tangents of the Bezier curve for the orientation.
The nodes at the end of the bone require some special handling to
deal with zero-length Bezier handles caused by a zero ease value.

The Copy Transforms constraint now also smoothly interpolates
rotation and scaling along the bone shape when enabled.

The initial version of the patch was submitted by @Sam200.

Cleanup: add View3D_Runtime struct

Also remove 'matcap_icon'

readme: separate development links

Add development links and place under own heading.

Merge branch 'master' into greasepencil-object

Fix T63563: Grease pencil not visible when contained in a collection instanced in a foreign scene.

The check of DUPLI object was used, but as the original object was not in the scene, the VBO data was not available and the draw was empty.

Now, the function checks if the original data is in the scene, and set the object as not Dupli to generate the VBO data.

3D View: move gizmo draw options out of overlays

Gizmo's now have their own popover in preparation
for making transform gizmos accessible without having to use tools
