Made UI changes. Removed binary weighting in average. Changed weight calculation.

Compiler pointer arithmetic fix.

Revert previous

2.79 RC2 + smooth-curves branch

Support Copy To Selected and Alt-Click for F-Curves in the curve editor.

This affects both the new smoothing mode setting and display color.

TEMPORARY HACK: convert the old flag to the new auto_smoothing enum.

Only for my branch build; not to be merged.

Implement a new automatic handle algorithm to produce smooth F-Curves.

The legacy algorithm only considers two adjacent points when computing
the bezier handles, which cannot produce satisfactory results. Animators
are often forced to manually adjust all curves.

The new approach instead solves a system of equations to trace a cubic spline
with continuous second derivative through the whole segment of auto points,
delimited at ends by keyframes with handles set by other requirements.

This algorithm also adjusts Vector handles that face ordinary bezier keyframes
to achieve zero acceleration at the Vector keyframe, instead of simply pointing
it at the adjacent point.

Original idea and implementation by Benoit Bolsee <benoit.bolsee@online.be>;
code mostly rewritten to improve code clarity and extensibility.

Make auto handle placement aware of cyclic extrapolation.

Cyclic extrapolation is implemented as an f-curve modifier, so this
technically violates abstraction separation and is something of a hack.
However without such behavior achieving smooth looping with cyclic
extrapolation is extremely cumbersome.

The new behavior is applied when the first modifier is Cyclic
extrapolation in Repeat or Repeat with Offset mode without
using influence, repeat count or range restrictions.

This change in behavior means that curve handles have to be updated
when the modifier is added, removed or its options change. Due to the
way code is structured, it seems it requires a helper link to the
containing curve from the modifier object.

Merge branch 'blender2.8' into greasepencil-object

Fix compiler error on win. (Arithmetic on void pointer)

Merge branch 'blender2.8' into greasepencil-object

New Onion skinning for select frames only

Add an option to display only the frames selected in dopesheet.

Heavily rework Amber's data model.

Since we want to be able to edit repo from within Blender, we'll need
UI-compatible representation of the repo.

Alas, PropertyGroup py instances are regenerated all the time, which
means we cannot store py-only data in those, so we have to go to a
triple representation of repo here (the JSON/dict one, the effective py
classes, and the UI-compatible PropertyGroup-based one).

Note that this is rather heavily WIP commit, it most certainly breaks
several things, but at least the basic repo listing from filebrowser is
working again...

Add some more protection against invalid data from asset engine.

Cleanup code and comments

Chnage angle limits to allow negative values

Change UI panel

Fix hair follicle array write/read.
