Cleanup: Indentation

Freestyle: Feature edge selection by nested object groups.

A group of object groups can be formed by means of the dupli_group option in
the Object properties window. The present revision extends the Selection by
Group option in the Freestyle Line Set so as to support not only flat object
groups but also nested groups.

Fix more corner cases failing in mesh faces split

Now we handle properly case with edge-fan meshes, which should
fix bad topology calculated for cash register which was causing
crashes in the studio.

Fix wrong edges created by split faces

We need to first split all vertices before we can reliably
check whether edge can be reused or not.

There is still known issue happening with a edge-fan mesh
with some faces being on the same plane.

[Alembic] Fix msvc warning - C4138 '*/' found outside of comment

Cycles: Cleanup, style

OpenGL immediate mode: sequencer_draw.c

Other than the general conversion:
* Made some slight aesthetic improvements.
** Removed gradients.
** Replaced stipples with transparency for hidden strips.
** Made strip borders less harsh.
** Removed stripes from offsets and made them brighter.
* Made only the visible parts of waveforms be drawn.
* Fixed a few drawing bugs.
** Background was not being drawn when buffer is NULL, and no
grease pencil is being drawn.
** Offset drawing ignored strip visibility.

Also, note that diagonal stripes for locked and error strips, are still
being drawn with the old api, as they await a new shader in order to
be converted.

Remove redundant draw call (sequencer)

`SEQUENCER_OT_slip` was calling `draw_sequence_extensions` to redraw the
extensions during modal operation, but that is redundant, as it is
already called by the regular draw loop. Because it was called on top of
the draw loop, it was actually obscuring other parts of the strip that
would normally be drawn on top of it.

Somewhat part of 49043

Remove "Object List" panel from collection context tab

Layers: Show collection objects in Outliner

Layers: Separate between scene render layer (F12) and context render layer (everything else)

For now they are the same. However with workspaces they will be
different, and should be treated differently.

Clay Engine: New collection settings (not working yet)

Collections Settings: Added Bool type.

Revert "Collection Editor based on patch by Julian Eisel"

This reverts commit 3da834e83ce9d7056c033148dab04885a6d3b1b7.

We will use the outliner for this now.

I'm also moving the collections_ops.c to outliner_collections.c

Add note to RNA about layer/engine macros

Fix T50542: Wrong metadata frame when using OpenGL render

Motion blur investigation feature

This commit adds a way to debug Cycles motion blur issues which
are usually happening due to something crazy happening in between
of frames. Biggest trouble was that artists had no clue about
what's happening in subframes before they render. This is at
least inefficient workflow when dealing with motion blur shots
with complex animation.

Now there is an option in Time Line Editor which could be found
in View -> Show Subframe. This option will expose current frame
with it's subframe to the time line editor header and it'll allow
scrubbing with a subframe precision in time line editor.

Please note that none of the tools in Blender are aware of
subframe, so they'll likely be using current integer frame still.

This is something we don't consider a bug for now, the whole
purpose for now is to give a tool for investigation. Eventually
we'll likely tweak all tools to be aware of subframe.

Hopefully now we can finish the movie here in the studio..

Immediate Mode: sculpt_uv.c

Fix sculpt brush draw crash on Blender2.8

Temporary solution by Sergey Sharybin, it needs further investigation.
This should not be necessary, specially since this works fine in master.

Fix T50662: Auto-split affects on smooth mesh when it sohuldn't

Seems to be a precision error comparing proper floating point
normal with the one coming from short.
