This change the logic a bit, when 2 bsdfs using SSS are mixed, we use the
one with the biggest radius (on a per pixel basis).
This change from previous behavior which was to select input 1 if radius
was greater than 0.
While not exactly optimal, that's the only disambiguation solution I
found doable for translations (i18n). ID names tend to sneak
everywhere, including in places where we have no access to i18n context
currently (like menu labels e.g.).
Other alternative would have been to use 'Lightweight', but that is a
tad too long, we love short UI messages as much as possible.
The genius who decided that it was critical to rename ID lamp to light
in 2.8 is welcome to find a better solution...

* Timeline has summary collapsed to show only one row of keyframes.
* Cavity default is screen space curvature (faster).
* Scripting workspace text editor uses syntax highlight and line numbers.
* Marker lines enabled by default in all animation editors.
* Movie clip editor pivot point default to median.

This is in order to create less shading group when using duplis.
Data for dupli objects keep in draw manager state until the source object
changes so retrieval is fast.
Note that this system could be extended to all meshes.
This is really close to BLI_mempool but uses an array to keep track of the
chunks of memory. There is no tagging necessary to clear the whole
structure so reuse is fast.
Naturally supports iteration but does not support freeing.
Not sure why newid was set in evaluated object instead of orig one,
makes no sense to me, since we want to operate remapping of ID pointers
on orig data? Looks like that was something overseen when that code was
ported to new COW system.
Since scale is multiplicative, the appropriate way to partially copy
it is to use power. However, the influence slider of constraints uses
linear interpolation. Thus, there is no way to correctly split scale
via constraints without adding this feature.
In addition, this allows inverting scale by using negative powers,
fulfilling the function of Copy Rotation's Invert checkboxes.
Add a new option that makes the Spline IK solver apply volume
preservation on top of the original scaling, considering the
pre-IK scale of the bone as the goal volume to be preserved.
This basically works similar to the Stretch To constraint, and
allows easily rigging a stretchy chain that uniformly follows
its parent's scaling.
Since the Stretch To behavior is more familiar, the new option
is on by default for newly created Spline IK constraints.
Perviously it was only possible to interpolate from the breakdown poses.
Now you can Push/Relax in regard to the rest pose as well.
For this only one keyframe is needed while the old modes needs two.
