This should decrease cognitive load because:
- Intention is more explicit
- Shorter visual scope of branches (no need to search for matching
closing brackets and `else` blocks)
- Visually less busy code because condition-checks and code that
"actually does things" are separated, with less indentation
- Avoids chaining together a bunch of conditions to a single `if`
Also: Use `const`, correct comment placement, whitespace improvements.
`BKE_nlastrip_find_active()` and `update_active_strip()` now do a more
thorough search for the active strip, by also recursing into
meta-strips.
There were some assumptions in the NLA code that the active strips is
contained in the active track. This assumption turned out to be false:
when there is a meta-strip, the active strip could be inside that, and
then it's not contained in `active_track.strips` directly.
Apart from the above, there are other situations in which the track
pointed to by `AnimData::act_track` does *not* contain the active strip
(even indirectly).
Both these cases can happen when the transform system is moving a strip
that's in tweak mode. Entering tweak mode doesn't just search for the
active track/strip, but also falls back to the last-selected ones. This
means that the track/strip pointers & flags can be out of sync with
what's being tweaked/transformed. Because of this, the assumption that
there is any relation between "active strip" and "active track" has been
removed from the `update_active_strip()` function.
All this searching could be prevented by passing the `AnimData` to the
code that duplicates tracks & strips. That way, when the active
track/strip is dup'ed, the `AnimData` pointers can be updated as well.
That would require more refactoring and thus could introduce other bugs,
so that's left for later.
This patch adds 4th option to Time offset modifier Modes.
It loops from start frame to end frame and then back to start in reverse direction.
In other words it is a combination of Normal and Reverse mode.
Especially with offset control it adds the ability to create easy looping animations such as cheering crowds, flowers opening and closing at different offsets.

Found those missing casts while looking into a crash report made in
the Blender Chat. Was unable to reproduce the crash, but the casts
should totally be there to avoid integer overflow.
* Rename ambiguous rgb to scene_linear in some places
* Precompute matrices to directly go to scene instead of through XYZ
* Make function signatures more consistent
Between scene linear and sRGB, XYZ, linear Rec.709 and ACES2065-1.
And add some clarifications about color spaces in the docs.

There are two issues. The biggest one was that a pixel value was used
to compare a squared distance meaning the tolerance was too strict.
The other issue was that the tolerance in pixels was different to what
the tracking mode is using.
The user-level change is that now it should be easier to tweak the
mask shape.
This is a place where the API function and operator should differ, for the API
manually setting the filepath and then saving should work. For the UI there is
no filepath visible, so it should open Save As even if there was a filepath set
for example from before changing an image type to Generated.
Some RNA property update callbacks can already generate such modifier,
and only one is allowed per object, so had to adapt code actually adding
new modifiers in liboverride apply codebase.
Also fixed an unreported issue of incorrect interpolation of thickness.

The 3D brush utility and the delete brush only considered segments,
so they did not handle single points. Fix by adding special cases for
single point curves.

For the "Sphere" 3D brushes, the depth and radius are only sampled at
the beginning of the stroke. This didn't work when tablet pressure is
used as a factor for the brush radius. Now the 3D brush depth is found
with the max radius (as if the pressure was 1.0), but the pressure
factor is used afterwards.
Restructuring the way the brush executors stored the radius made
the change a bit clearer, which is where most of the diff comes from.

This uses the recently introduced evaluator's vertex
data to smoothly interpolate original coordinates instead
of using linear interpolation.
The orcos are interpolated at the same time as positions
and as such, the specific subdivision routine for the
orco extractor has been removed. The patch evaluation
shader uses a definition to enable code specific to
orco evaluation.
Since the orco layer may not have been requested on first
render, and since orco data is now stored in the OpenSubDiv
evaluator, the evaluator needs to be recreated if an
orco layer is suddenly available. For this, a callback
to check if the evaluator has the data was added. This is
added to the evaluator as the `Subdiv` cache stored in the
modifier is invalidated less often than the Mesh batch cache
and so leads to fewer evaluator recreations.

Previously we would pass button state and draw information to widget
draw callbacks in a rather hacky way. Some specific flags from
`uiBut.flag` were masked out, so their bits could be reused for also
passing `uiBut.drawflag` in the same int. Instead this commit introduces
a state-info struct that can properly hold all the relevant data.
This has the advantage that it's now easier to introduce new state data
that needs to be accessible in the widget callbacks. Since we are
running out of button flags, we plan to reorganize button flags, and
split them up into multiple bitfields. In the widget drawing code, this
would have been a hassle earlier.
Also had to add a new widget callback to draw blocks as widgets (popup
backgrounds), since that would pass block flags where we would usually
pass button flags. This wasn't nice, now it's separated more clearly.
This patch changes the Text Box Width socket to always have that label
instead of switching to "Max Width" when Overflow mode is picked.
