The Random Per Island attribute is a random float associated with each
connected component (island) of the mesh. It is particularly useful
when artists want to add variations to meshes composed of separate
units. Like tree leaves created using particle systems, wood planks
created using array modifiers, or abstract splines created using AN.

This was added years ago to prepare for code-signing the executable
but was never used, buildbots use a different mechanism now to sign
so no need to keep this around.
This function exposes the already-existing static `object_moves_in_time()`
function, and optionally recursively checks the parent object for
animatedness as well.
I also added checking `AnimData::overrides` to
`BKE_animdata_id_is_animated()`. This ensures that, apart from the optional
recursion to the parent object, the function has the same functionality.
Instead of always writing the transform on every frame, it's now checked
whether the object is animated at all. This could be made stricter to
reduce false positives, for example by checking FCurves and drivers to
see whether translation/rotation/scale is animated. However, this
approach is already better than the `return true` we had before.
This commit adds the BKE_animdata_id_is_animated(id) function, which
returns true if the ID datablock has non-empty animation data. This is
determined by checking the the active action's fcurves, the drivers, and
NLA tracks.
The function isn't used anywhere, and it's deceptively returning false
negatives. For example, `modifier_dependsOnTime()` will return `false`
for hook modifiers, even when the hook target is animated. Querying the
depsgraph for dependency on the time source would be a better approach.
The `modifiers_getVirtualModifierList()` function previously took a non-
const `Object *ob` parameter, preventing it from being called from more
restrictive functions. Since the function doesn't modify the passed
object, it could easily be made const.
No functional changes.
This code allows to push a set of different operations all based on
iterations over a range of indices, and then process them all at once
over multiple threads.
This commit also adds unit tests for both old un-pooled, and new pooled
task_parallel_range family of functions, as well as some basic
performances tests.
This is mainly interesting for relatively low amount of individual
tasks, as expected.
E.g. performance tests on a 32 threads machine, for a set of 10
different tasks, shows following improvements when using pooled version
instead of ten sequential calls to BLI_task_parallel_range():
| Num Items | Sequential | Pooled | Speed-up |
| --------- | ---------- | ------- | -------- |
| 10K | 365 us | 138 us | 2.5 x |
| 100K | 877 us | 530 us | 1.66 x |
| 1000K | 5521 us | 4625 us | 1.25 x |

Note: Compared to previous commit yesterday, this reworks atomic handling in
parallel iter code, and fixes a dummy double-free bug.
Now we should only use the two critical values for synchronization from
atomic calls results, which is the proper way to do things.
Reading a value after an atomic operation does not guarantee you will
get the latest value in all cases (especially on Windows release builds
it seems).
By error, the original datablock was used while rendering. Actually, only while the user is drawing the original data must be used because when we tested, the time the system uses to copy the datablock created a very bad "lag" feeling while drawing. Maybe the lag was half second only, but it ruined the pencil feeling.
I talked some time ago with Sergey about that and we decided use this approach.
Now, only the original datablock is used while the user is "moving" the pen, but not in any other situation.
Thanks @sergey for help me with this bug and sorry for thinking it was a depsgraph issue.
The new Mapping node was missing versioning code for drivers.
This patch refactors existing code and add versioning for drivers.

Adds a `text` parameter to `bpy.types.uiLayout.template_ID()` which
causes a label to be added, as usual. Adding the label also makes the
template respect the `bpy.types.uiLayout.use_property_split` option.
Also fixes wrong layout being used in the template-ID, although I think
that didn't cause issues in practice.
Sergey requested this for usage in the Movie Clip Editor.
Adds a theme setting to specify color of widget text insertion cursor (caret).

When scrollbars were redesigned, the size of UI-List scrollbars wasn't
updated. Those were still huge.
This makes their size consistent with other scrollbars and frankly,
non-rediculous.
Add smooth scrolling support for vertical scrolling.
This is only active while scrolling so we don't need to support
pixel-level offsets for operators, interactions.
