Those (aka root node trees and master collections) share same 'traits'
as the shapekeys: RNA cannot assign them, so we need to handle them as
sub-data of their owner IDs.
Not sure how much this will help in improving support of overrides for
scenes and nodetrees, but this is a mandatory step towards that goal for
sure.
We should now have the tools to ensure consistency of ID pointers
diffing in `rna_property_override_diff_propptr`.
As a reminder, for most ID pointers we just check the actual pointer value,
but this is not possible for embedded IDs like root node trees or master
collections, and for fake embedded ones like shapekeys, so those should be
handled as mere sub-data of their owner IDs in override context.
Code generating override operations would not deal properly with Pointer
RNA properties, trying by default to use and check pointers' names
properties like it does with items of a collection.
However, using name property in pointer RNA property case makes no
sense, so specialize the `no_prop_name` flag for each case (pointer or
collection).
here, since second override would generate local data-blocks with
different names than the linked data ones, name matching would fail and
breck handling of override diffing in shapekeys.
Note that shape keys are the only one concerned by that problem, since
other embedded IDs (root node trees and master collections) are fully
real ones, so they always get the same names.
Our beloved shapekeys are 'virtual' overrides, they need special
snowflake treatment here as well.
They do not have any override data, from override perspective they are
considered as mere sub-data from their owning ID (mesh, lattice, etc.).
Therefore, we should not copy override data from them, but instead
properly flag those new IDs as `LIB_EMBEDDED_DATA_LIB_OVERRIDE`.
Found while investigating T84373.
This commit adds the ability to provide a default value to
`attribute_try_get_for_output` and uses it for the `Point Scale` node,
which is important because the node uses multiplication.
The idea is to keep "name-specific" functionality in nodes rather than in
the attribute API, otherwise the complexity will be hard to keep track of.
So this fix doesn't apply to the Attribute Vector Math node, but hopfully
that is okay since that's now a lower level node for this purpose anyway.

Use exact marker accessor. Harmless due to the current way the
transform system is used by tracking. But for the future development
proper accessor needs to be used.
Cycles has a lot of code like this:
```lang=c++
BL::Object::modifiers_iterator b_mod;
for (b_ob->modifiers.begin(b_mod); b_mod != b_ob->modifiers.end(); ++b_mod) {
```
Range-based for loops allow us to simplify this to:
```lang=c++
for (BL::Modifier &b_mod : b_ob->modifiers) {
```
In order to support this, a collection (such as `b_ob->modifiers`) must have
a `begin()` and `end()` method, that take no parameters and return an iterator.
The `end` method already exists, but the `begin` method takes the iterator as
argument currently.
This patch adds a new `begin` method that returns the iterator. The old `begin`
method is still available to avoid breaking existing code.
My assumption is that the old `begin` method took the iterator as parameter so
that the iterator is not copied or moved, i.e. its memory address is stable and
the destructor is only called once. I'm not sure if both of these requirements
are really necessary to ensure that the iterators work correctly. To be on the
safe side, I deleted the copy/move constructors/assignment operators.
Since C++17 there is "guaranteed copy elision" which basically allows us to
return a non-copyable and non-movable type from a function. To make that work,
I had to add a new constructor to `CollectionIterator` that calls `begin` on itself.

The clarity is more for consistency with the nla domain() processing

When NLA strips weren't time-aligned with the underlying action, then
fcurve modifiers would not be drawn anchored to the strip. Fmodifiers
were evaluating properly, they just weren't drawn with the proper
offset and scale.
To fix it in this specific case, I've chosen to undo the keyframe
remapping then remap the draw-evaluation-time from scene time to
fcurve time. Afterward, I redo the keyframe remapping so the controls
are properly drawn.
The Envelope fmodifier has special drawing code which was fixed too. In
this case, no mapping at all was happening. The solution was similar,
to remap the envelope control points from fcurve time to scene time.
This patch adds a noise offset option to the grease pencil noise modifier.
It allows the user to animate the noise along the length of the stroke to create movement that is currently not possible.
It works by adding an offset to the noise table and adding the remaining floating point value to the noise table sampling.

Instead of submitting tons of tiny IO syscalls, we can speed things up
significantly by `mmap`ing the .blend file into virtual memory and directly
accessing it.
In my local testing, this speeds up loading the Dweebs file with all its
linked files from 19sec to 10sec (on Linux).
As far as I can see, this should be supported on Linux, OSX and BSD.
For Windows, a second code path uses `CreateFileMapping` and
`MapViewOfFile` to achieve the same result.

Note that uv layers still can't be accessed with nodes, because those
only access attributes on the point domain currently, while uv data
is stored per corner. Implicit domain conversion hasn't been
implemented yet.
Some of these conversions are arbitrary to some degree.
However, the user experience is better when at least something
happens when converting between types, instead of just getting
zeros. I left out a few conversions that I wasn't sure about yet.
I also added conversions for float2.
This fixes the behavior of some nodes when the same attribute
name is used for input and output. If both attributes have a
different type, they can't exist at the same time. Therefore,
the input attribute has to be removed in order to create the
output attribute.
Previously, the input attribute was remove before it was used
in any computations. Now, the output is written to a temporary
buffer and only later saved in the geometry component. This
allows both attributes to coexist within the node.
The temporary attribute is only create when necessary. The
normal case without name collisions still works the same
as before.

Fixes a number of glitches, e.g. the sidebar disappearing when selecting an

There were a couple of issues:
* Execution region was created, but not used.
* If an execution region already existed when refreshing the area, it was
tagged as hidden, not removed.
* The sidebar was always set to be hidden on refreshes.
* When toggling from Asset Browser to File Browser as regular editor (i.e. not
opened temporary via Ctrl+O or such), the sidebar region wasn't removed.

The other output types did not work currently anyway.
There is not a significant benefit in somehow deducing the output
attribute type from the existing attribute types.
`ED_undo_gpencil_step` only support valid undo step direction, passing
step name here is useless and only add confusion to what works or not.
Undo by step name or step index is fully not supported by GPencil undo

Note that since GPencil undo mode does not seem to ever be used anyway,
this is not an urgent issue in practice, but this needs to be cleaned up
at some point. See also T84703.
Handle return value of `fread()`, by showing an error message when the

Before transform cancel will request marker at a current frame number
and restore transform flags to it. This worked fine if there was only
one marker from track in the transform data. This did not work correct
when multiple markers from track were added to transform data.
This allows to implement proportional editing in the clip editor.
Allows to easily implement more comprehensive checks about which
markers get added to the transformation context.
No user measurable changes are expected, purely house-keeping to
ease an upcoming development.
Reduce amount of duplicated pointer offset logic: advance transform
data pointers deep in the loop rather than have offset duplicated in

Array size calculation still has duplicated, but that is another story.
The deform parameter of the Bmesh from_object method is deprecated,
always assumed to be True, and will be removed in version 3.0.
That is because the cases where it is False don't work correctly and are

is the application of constructive modifiers twice if the input object
