While it's useful for click-drag to leave the selection as-is
(when clicking on items that are already selected), it's useful
for a single click to de-select all other elements.
This also removes the need for the initial selection to set the object
as active since this is possible by clicking on it.
Using the evaluated lengths cache from 72d25fa41d, re-implement
the curve parameter node with the new data structure. Conceptually
it works the same way, but the code is restructured and cleaned up
a bit as well. This also adds support for Catmull Rom curves.

The idea that curves with two points cannot be cyclic came from some
existing code, but there's not fundamental reason for it, so remove the
check in this function. The case can be handled elsewhere if necessary.
This commit adds calculation of lengths along the curve for each
evaluated point. This is used for sampling, resampling, the "curve
parameter" node, and potentially more places in the future.
This commit also includes a utility for calculation of uniform samples
in blenlib. It can find evenlyspaced samples along a sequence of points
and use linear interpolation to move data from those points to the
samples. Making the utility more general aligns better with the more
functional approach of the new curves code and makes the behavior
available elsewhere.
A "color math" header is added to allow very basic interpolation
between two colors in the `blender::math` namespace.

Fix small cosmetic issues with the reroute node:
1. Remove special case that allowed curved links to attach vertically.
2. Center align the reroute node's label.
The vertically attached node links could lead to kinks in the otherwise
smooth curves. This would break the visual flow and make the link
potentially intersect the node's label.
The center alignment of the label gives more consistent results for
different label lengths and also reduces the chance of the label
interfering with the node links.

Don't always create a new geometry nodes node tree when adding a
geometry nodes modifier.
This avoids files getting cluttered with empty and unused geometry node
trees that are created every time a nodes modifier is added to an
object - even if only to apply an already existing.
This is also more consistent with other modifiers that also don't
automatically create new data blocks.
The new modifier still automatically gets populated with a new node
tree when adding it via the "New" button in the header of the
geometry nodes editor.

Add new `BKE_id_is_editable` helper in `BKE_lib_id.h`, that supercedes
previous check (simple `ID_IS_LINKED()` macro) for many editing cases.
This allows to also take into account 'system override' (aka
non-editable override) case.
Ref: {T95707}.
'Delete' was a confusing name, even though it would delete the overrides
it would replace them by linked data.
Adding the 'single' version of that operation made it even more
confusing, since often it has to keep the override ID for sakes of
hierarchy, and just reset it and turn it back into a non-editable system
override.
Ref: {T95707}.
Implement default behavior to decide which overrides remain 'system'
ones, and which become 'user editable' ones, when creating hierarchy
override from 3DView or the Outliner.
3DView:
If from an Empty-instanced collection, only Armature objects in
that collection are user overrides.
If from a set of selected objects, all overrides created from selected
objects are user overrides.
Outliner:
All override IDs created from selected elements in the Outliner are user
overrides.
There is one special case: When a collection is selected, and is
'closed' in the outliner, all its inner armature objects are also user
overrides.
Ref: {T95707}.
When creating with hierarchies, core code only generates system
overrides, responsibility to define 'user overrides' is then for the
higher-level calling code (Editor/Operator-level).
do_version code uses fairly basic euristics, should be good enough here
though in most cases. and can always be refined later if needed.
Ref: {T95707}.
The whole liboverride data is still ignored by override diffing etc.,
but some of their flags should be editable (from script and/or advanced
technical/debug UI). So using a weird combination of flags to achieve
this.
Ref: {T95707}.
This merely adds the flag, exposes it in RMA, and uses it in some of the
most common 'is editable' checks (RNA, `BASE_EDITABLE` macro...).
Next step: do_version and defining systemoverrides at creation.
Ref: {T95707}.
The "dupli" system now has a faster, more powerful, and more flexible
alternative with geometry nodes. Since the point cloud objects haven't
been exposed in the non-experimental UI yet, we can remove the dupli
implementation and the panel for the object type.

Adds supports for collection previews that are rendered automatically when
collections are marked as assets. (Or when preview rendering is triggered
differently, e.g. through the //Refresh Data-Block Previews// operator).
Idea in this patch is to create a collection instance empty outside of main for
the collection, and then reuse the object rendering code to render the preview.
This keeps things very simple and works just fine.

Error exposed by ba49345705. Code just assumed that the tree-element
pointed to a real ID, but this is often not the case, and the ID pointer
contains completely different data. E.g. before ba49345705, it would
be a pointer to one of the `Main` listbases, so this code would have
undefined behavior. Now the pointer is null for elements in the "Current
File" element, causing a null-pointer dereference rather than undefined
behavior (that just happened to virtually always result in the intended
code path).
The indirect library data icon was just a grayed out version of the
regular one. This graying out is now done in code, so the icon can be
removed from the SVG. Note that the icon is still defined as
`ICON_LIBRARY_DATA_INDIRECT` (or `LIBRARY_DATA_INDIRECT` in BPY).
The lines paint mask IBO extraction was not implemented for GPU subdivision.
For it to work, we also now need to preserve the subdivision loop to
subdivision edge map, which until now was overwritten to store coarse edges
(the map to coarse edges is still preserved).
Also the paint flag stored in the 4th dimension of the loop normal buffer
was not properly set for flat shaded faces, leading to other kind of
artefacts and render issues.
The problem was when the stroke had less weights that the total number of vertex groups.
The API checked the total number of groups, but this is not required because `BKE_defvert_find_index` returns NULL is the vertex group index does not exist.
If creating partial hierarchy overrides (from the outliner e.g.), that
need to create extra overrides, those could be re-created everytime,
leading to very bad situation where there would be several overrides of
the same reference ID in the same override hierarchy.
This fix makes it so that existing overrides in a given hierarchy will
always be re-used in case other overrides are added to the hierarchy.
Replaces old-style memzero-style of call with zero-initializer.
Allows to shorten typical initialization code to a single line:
Object foo = blender::dna::shallow_zero_initialize<Object>()
This will allow to more easily convert designated initializer
which is often used to fill object with zeroes to the explicit
function calls:
MyDNAStruct foo = {};
will be translated to
MyDNAStruct foo = blender::dna::shallow_zero_initialize<MyDNAStruct>();

Previously, those methods would destruct and reconstruct
the data structure. While that was more simple in initial
implementation, it has some downsides which are not resolved:
* Already allocated memory is lost. So new memory would have
to be allocated when the data structure is refilled.
* The clearing process itself was slower because it did unnecessary
work.
This simplifies debugging, and can help improve performance
by making it easier for the compiler.
More optimization might still be possible by using `__restrict` in
a few places.
