* Curves objects now support the geometry nodes modifier.
* It's possible to use the curves object with the Object Info node.
* The spreadsheet shows the curve data.
The main thing holding this back currently is that the drawing code
for the curves object is very incomplete. E.g. it resamples the curves
always in the end, which is not expected for curves in general.

**Relevant to Artists:** This patch adds an option to the Parenting
menu, `Object (Keep Transform Without Inverse)`, and Apply menu, `Parent
Inverse`. The operators preserve the child's world transform without
using the parent inverse matrix. Effectively, we set the child's origin
to the parent. When the child has an identity local transform, then the
child is world-space aligned with its parent (scale excluded).
**Technical:** In both cases, the hidden parent inverse matrix is
generally set to identity (cleared or "not used") as long as the parent
has no shear. If the parent has shear, then this matrix will not be
entirely cleared. It will contain shear to counter the parent's shear.
This is required, otherwise the object's local matrix cannot be properly
decomposed into location, rotation and scale, and thus cannot preserve
the world transform.
If the child's world transform has shear, then its world transform is
not preserved. This is currently not supported for consistency in the
handling of shear during the other parenting ops: Parent (Keep
Transform), Clear [Parent] and Keep Transform. If it should work, then
another patch should add the support for all of them.

Add a new operator, "Start Tweaking Strip Actions (Full Stack)", which
allows you to insert keyframes and preserve the pose that you visually
keyed while upper strips are evaluating,
The old operator has been renamed from "Start Tweaking Strip Actions" to
"Start Tweaking Strip Actions (Lower Stack)" and remains the default for
the hotkey {key TAB}.
**Limitations, Keyframe Remapping Failure Cases**:
1. For *transitions* above the tweaked strip, keyframe remapping will
fail for channel values that are affected by the transition. A work
around is to tweak the active strip without evaluating the upper NLA
stack.
It's not supported because it's non-trivial and I couldn't figure it
out for all transition combinations of blend modes. In the future, it
would be nice if transitions (and metas) supported nested tracks
instead of using the left/right strips for the transitions. That
would allow the transitioned strips to overlap in time. It would also
allow N strips to be part of the (previously) left and right strips,
or perhaps even N strips being transitioned in sequence (similar to a
blend tree). Proper keyframe remapping through all that is currently
beyond my mathematical ability. And even if I could figure it out,
would it make sense to keyframe remap through a transition?
//This case is reported to the user for failed keyframe insertions.//
2. Full replace upper strip that contains the keyed channels.
//This case is reported to the user for failed keyframe insertions.//
3. When the same action clip occurs multiple times (colored Red to
denote it's a linked strip) and vertically overlaps the tweaked
strip, then the remapping will generally fail and is expected to
fail.
I don't plan on adding support for this case as it's also non-trivial
and (hopefully) not a common or expected use case so it shouldn't be
much of an issue to lack support here.
For anyone curious on the cases that would work, it works when the
linked strips aren't time-aligned and when we can insert a keyframe
into the tweaked strip without modifying the current frame output of
the other linked strips. Having all frames sampled and the strip
non-time aligned leads to a working case. But if all key handles are
AUTO, then it's likely to fail.
//This case is not reported to the user for failed keyframe
insertions.//
4. When using Quaternions and a small strip influence on the tweaked
Combine strip. This was an existing failure case before this patch
too but worth a mention in case it causes confusion. D10504 has an
example file with instructions.
//This case is not reported to the user for failed keyframe insertions. //
5. When an upper Replace strip with high influence and animator keys to
Quaternion Combine (Replace is fine). This case is similar to (4)
where Quaternion 180 degree rotation limitations prevent a solution.
//This case is not reported to the user for failed keyframe insertions.//

F2 allows renaming lots of different types of active items, and now it
also works for markers.
Before, Ctrl+M was used, and it's context-sensitive: you often get
"Mirror Keys" instead, when your cursor isn't on the markers region, and
that operator has nothing to do with either renaming or markers.

- Replace Ctrl+M shortcut with F2.
- Adds the `TOPBAR_PT_name_marker` panel which is implemented similar
to the global rename panel. This having to press enter twice to

Unlike regular selection cycling that is activated when clicking again
in the same location, object mode would cycle to another object
if the object that was selected happened to already be active.
This made it impossible to click-drag to tweak the active object
if there were other objects behind it as those would be activated first.

Use Alt-Slash to remove objects from local-view (was M prior to [0]),
following the convention of using Alt to perform the reverse of an
action. Also remove the confirmation menu as this key as it can be
undone and it's not likely to be pressed by accident.
This can be useful to quickly subtract items from a complex selection
with items that only become visible when entering local-view.
The M key was originally used in 2.4x since moving between layers wasn't
possible. Now moving between collections is possible in local-view
the keys collided.
[0]: cf5d582b77
This behaviour was introduced in a687d98e67 to bring the old obscure
"M" operator to remove objects from the local view. In order to avoid
the keymap clash with the Move to Collection operator, the Move to
Collection was artificially restricted to work in local view.
In retrospect, the "Remove from Local View" operator is in the menu anyways,
so it didn't even need to have a shortcut (back in 2.79 the operator was
not in a menu).
The changes introduced here are:
* No shortcut for "Remove from Local View"
* No more restrictions to "Move/Link to Collection" from local view.
Thanks for Philipp Oeser for digging the old commit that introduced this
and for the rationale on the changes.
The new tab in the properties panel for "Color Attributes" shows the
data type and domain, just like the Attributes tab.
The issue is that the UI does not scale well and can only display the
full names when dragged to an extreme width.
This is due to the inclusion of the render icon in between the
attribute name and attribute type description.
This patch changes the order that items are displayed in the Color
Attributes Panel. Moving the render icon to the very right.
The result is consistent with other parts of the Blender UI and does
not take as much space to display the full text.

The menu with the options was not visible because the tool checked must be the sculpt, not draw.
This was broken in old version, but I cannot determine when or if never worked at expected.
This patch adds color attributes to TexPaintSlot. This allows an easier selection
when painting color attributes.
Previously when selecting a paint tool the user had to start a stroke, before the
UI reflected the correct TexPaintSlot. Now when switching the slot the active
tool is checked and immediate the UI is drawn correctly.
In the future the canvas selector will also be used to select an image or image texture node
to paint on. Basic implementation has already been done inside this patch.
A limitation of this patch is that is isn't possible anymore to rename images directly from
the selection panel. This is currently allowed in master. But as CustomDataLayers
aren't ID fields and not owned by the material supporting this wouldn't be easy.

This operator snaps the first point of every curve to the corresponding
surface object. The shape of individual curves or their orientation is
not changed.
There are two different attachment modes:
* `Nearest`: Move each curve so that the first point is on the closest
point on the surface. This should be used when the topology of the
surface mesh changed, but the shape generally stayed the same.
* `Deform`: Use the existing attachment information that is stored
for curves to move curves to their new location when the surface
mesh was deformed. This generally does not work when the
topology changed.
The purpose of the operator is to help setup the "ground truth"
for how curves are attached to the surface. When the ground
truth surface changed, the original curves have to be updated
as well. Deforming curves based on an animated surface will be
done with geometry nodes independent of the operator.
In the UI, the operator is currently exposed in curves sculpt mode
in the `Curves > Snap Curves to Surface` menu.

Avoid errors in the legacy Pose Library panel (in Armature properties)

While these settings still affect the particle hair system,
the idea is that if we have to choose one naming scheme to align

system is considered a legacy feature.

- "Principled Hair BSDF" is not affected since it's meant for hair.

This patch adds channel region to VSE timeline area for drawing channel
headers. It is synchronizedwith timeline region. 3 basic features are
implemented - channel visibility, locking and name.
Channel data is stored in `SeqTimelineChannel` which can be top-level
owned by `Editing`, or it is owned by meta strip to support nesting.
Strip properties are completely independent and channel properties are
applied on top of particular strip property, thus overriding it.
Implementation is separate from channel regions in other editors. This
is mainly because style and topology is quite different in VSE. But
also code seems to be much more readable this way.
Currently channels use functions similar to VSE timeline to draw
background to provide illusion of transparency, but only for background
and sfra/efra regions.
Great portion of this patch is change from using strip visibility and
lock status to include channel state - this is facilitated by functions
`SEQ_transform_is_locked` and `SEQ_render_is_muted`
