Numerical inputs have little arrows on the left and right to allow
quick increment/decrement of the value. But these are only shown on
hover, which does not help if using a device that does not have a hover
state (some pens, most touch). This PR adds a user preference to show
them always.

Add "Reduce Motion" option to a new `Accessibility` panel under
Preferences, User Interface.
"Reduce Motion" avoids non-essential animation effects, especially
useful for those experiencing motion sickness/vertigo.
It affects:
* Region open/close.
* Pie menus animation.
* Smooth views.
This panel in the future could host common accessibility settings such
as "Increase Contrast" or font size and weight controls that currently
are part of themes.
See PR for details and screenshots.

* Store scene linear to XYZ conversion matrix in each blend file, along
with the colorspace name. The matrix is the source of truth. The name
is currently only used for error logging about unknown color spaces.
* Add Working Space option in color management panel, to change the
working space for the entire blend file. Changing this will pop up
a dialog, with a default enabled option to convert all colors in
the blend file to the new working space. Note this is necessarily only
an approximation.
* Link and append automatically converts to the color space of the main
open blend file.
* There is builtin support for Rec.709, Rec.2020 and ACEScg working spaces,
in addition to the working space of custom OpenColorIO configs.
* Undo of working space for linked datablocks isn't quite correct when going
to a smaller gamut working space. This can be fixed by reloading the file
so the linked datablocks are reloaded.
Compatibility with blend files saved with a custom OpenColorIO config
is tricky, as we can not detect this.
* We assume that if the blend file has no information about the scene
linear color space, it is the default one from the active OCIO config.
And the same for any blend files linked or appended. This is effectively
the same behavior as before.
* Now that there is a warning when color spaces are missing, it is more
likely that a user will notice something is wrong and only save the
blend file with the correct config active.
* As no automatic working space conversion happens on file load, there is
an opportunity to correct things by changing the working space with
"Convert Colors" disabled. This can also be scripted for all blend files
in a project.

This feature works like the select lasso in other editors. In preview
the user can draw a region they want to select and when a strips origin
is in this lasso region the strip gets selected.
In timeline the user can do the same and the strip gets selected when
the strip is in the lasso or some part of the lasso is in the strip.
The tool can be accessed through in the toolbar or via shortcut.

An existing node converts a value (float) to string. This node is intended as a conversion in
the other direction. If parsing is unsuccessful, floating point 0 is output. This node also
outputs the length of the parsed string (i.e. the index of the first character where the
number stopped).

Added support for string sockets in `nw_merge_nodes`, results in

This PR updates the VSE strip modifiers interface.
It now uses the same design as the object modifiers.
Changes:
* Except for the "Mask Input" subpanel, the modifier UIs are unchanged.
* Modifiers can now be rearranged using drag & drop.
* Additionally, there is now an active strip modifier. This is exposed
though python via `strip.modifiers.active`.
This is in part for !139634 which needs the concept of an active modifier.
Notes:
* The `modifier.cc` file included all the implementation of all modifiers.
With the addition of a another new callback in this PR, this file was
getting quite big so I split everything out into individual files for all
modifiers. The modifiers are getting registered at launch.
* The modifier panels are getting added using a UI template
(`template_strip_modifiers`) very similar to the object modifiers.

This feature works like the select circle in any other modes. The user
can press "C" in preview or timeline and then select or deselect strips
by pressing the left or middle mouse button.
It’s an enhancement for the VSE preview because:
1. It makes it more similar to other editors in Blender
2. This behavior makes it easier to select specific overlapping strips
in preview, that is because the select circle only checks for the
origin of the strip.

Now that there are Rec.2100 PQ and HLG displays, the additional HDR option
for video export is redundant. Typically you would now select a HDR display
early on and do all your video editing with it enabled.
For saving a HDR video, the encoding panel will now show the name of the color
space, and warn when the video codec or color depth is incompatible.
Since this is now based on interop IDs for the dislpay color spaces, we can
map more of those to the appropriate CICP code. This works fine for Display P3,
in my tests it looks identical to sRGB except that the wide gamut colors are
preserved.
However Rec.1886 and Rec.2020 are problematic regarding the transfer function,
although the latter at least has the correct primaries now. So it should be
a net improvement and this could be looked at later if anyone wants.
---
Background:
* Rec.1886 and Rec.2020 display color spaces in Blender use gamma 2.4.
* BT.709 trc is almost the same as gamma 2.4, so seems like the correct choice.
* We already write sRGB with BT.709 trc, which seems wrong.
* Yet sRGB matches exactly between Blender display and QuickTime, while
Rec.1886 and Rec.2020 do not.
* Display P3 with BT.709 trc matches sRGB with BT.709 trc, just adding the wide
gamut colors. So that is what is used for now. Also using the sRGB trc the
file is not recognized by QuickTime.
There is apparently a well known "QuickTime gamma shift" issue, where the
interpretation of the BT.709 trc is different than other platforms. And you need
to do workarounds like writing gamma 2.4 metadata outside of CICP to get
things to display properly on macOS.
Not that QuickTime is necessarily the reference we should target, but just to
explain that changing the previous behavior would have consequences, and so
it this commit leaves that unchanged.

Add back custom properties to nodes, and properly expose them in the UI
as such (new 'Custom Properties' panel for nodes in the the Node
Editor).
This shows like any other custom property panel in the UI, in the Node editor:
<img width="424" alt="image.png" src="attachments/adb50815-0db0-447f-ac3b-7860d9a3e3fc">
Although not initially intended for this, nodes 'mixed' IDProperties
were quite widely used by py/extensions developers to store per-node
data.
During the initial IDProperties split between User-defined (aka custom
data) and system-defined (runtime RNA properties), this was not known,
so decision was made to only keep system properties for Nodes. The fact
that these properties were not exposed at all in UI also played a role
in that decision. See also discussions in #141042.
This commit instead splits system properties out into their own new
storage, and keep existing ones for user-defined/custom properties
(as done for other IDProperty owners, like IDs, bones, etc.).

This applies an OpenColorIO display, view and look transform on a color
in the scene_linear colorspace.
In general, OpenColorIO configurations do not contain a colorspace for
every view + display, especially if they are modern configs using the
display colorspace and shared view mechanisms. Nor do they include looks.
So the Convert Colorspace node is not sufficient.
Additionally, we would like to avoid making the colorspace list too long
in the default config, as we are adding many new views and transforms.
Exposure, gamma curves and white point functionality are not included
in this node, as there are native ways of doing that in the compositor.
These settings are marked non-editable in the Python API.

This commit changes the internal storage and user-facing representation
of the brush size values (`size` and `unprojected_size`) from radius
to diameter.
This has a number of benefits:
* While the radius is more helpful for many internal operations, it is
more natural to estimate the size of a brush by the diameter
* Because the pixel size is stored as an integer, users are currently
unable to make brushes that have an odd numbered diameter, notably
preventing the ability to make single pixel brushes.
Internally, the `Brush` and `UnifiedPaintSettings` size values are
versioned to double their on-disk values. The relevant `BKE` functions
that access the data return the radius at runtime, and any internal
`struct`s that stored radius continue to do so.
The 'Radius' text for brushes is changed to 'Size' and all references
to it in descriptions are changed to 'size' as well.

This PR moves keyframe theme properties from editors into Common.
Besides Dope Sheet, keyframe properties were in:
- Sequencer (almost all types, and might use more in the future)
- 3D Viewport, where the active object name overlay used a separate Object Keyframe color when
it had keyframes on the current frame. Now it uses the common Keyframe Selected color, instead
of having its own property just for this little text.
- Keyframes in Movie Clip Editor were hard-coded white, now they use a common Keyframe color.
Selected colors used wrong long key selected color, now they use common Keyframe Selected color.
- Movie Clip Editor also used separate colors for what it called "Strips", but they are visually
the exact same thing as "long keys" in Dope Sheet, so they use common long key colors now.
There are Keyframe Border properties in Dope Sheet, Sequencer, and NLA, but they're not shared
because they're drawn on very different backgrounds, in different sizes, with different fill colors, so
it's difficult to make one color work for all of them, and it can restrict customization and accessibility.

Details:
- Long keys in Dope Sheet/Clip Editor and Strips in NLA used the same internal "strip" attribute.
Those needed to be separated to properly use long key colors in common, without worrying
about affecting unrelated things, and those two are as unrelated as they can get.
To properly separate them I added new "long_key" attributes, and corresponding
`TH_LONGKEY` and `TH_LONGKEY_SELECT`.
- Long keys in Movie Clip Editor had hardcoded alpha. Now they use alpha of the theme color.

The pose library registered a double-click keymap item for the file
browser keymap, because that was the only way to add keymap items to the
asset browser (which is just the file browser under the hood). Since
450f428434, the pose library apply & blend operators are available in
more contexts, since their check for an active asset was moved from the
operator poll to the operator execution. So the pose apply operator
would end up triggering.
The poll function could be adjusted somehow to return false in this
case, e.g. by checking if it's executed from a file browser (not an
asset browser).
However, the operator should be independent of where it's called from.
So instead this registers a separate keymap for the asset browser, so
the pose library operators can be registered exclusively for the asset
browser.
Selected tracks in the Movie Clip Editor's Dope Sheet used hard-coded color.
Added a new theme property for them, and previously hard-coded color is now just a default.

This was quite involved to get to work. Basic idea is to make
`bl_activate_operator` work for the pose library asset shelf, and
introducing a `bl_drag_operator` for blending poses.
- Make pose asset operators take an asset reference, which is how
`bl_activate_operator` usually gets the asset to operate on. This way
poses references can be assigned to a shortcut, identified by asset
library and relative asset path within the library. Falls back to
getting the asset from context.
- Trigger `bl_activate_operator` on every click, instead of only when
an un-active item becomes active. Needed so poses can be re-applied
as before.
- Fix button context not passed to the `bl_activate_operator` when
force-activating, e.g. on right-click events.
- Allow registering a `bl_drag_operator` in the asset shelf definition.
Executed when dragging an asset in the shelf.
- When dragging an asset, highlight it as active, without calling the
`bl_activate_operator`. This is important feedback to the user.
- Activate/select view items on click instead of drag, so dragging is
possible.
- Let pose applying operators handle the Ctrl key to apply poses
flipped. There's no simple way to attach such alternative behaviors
to `bl_activate_operator`/`bl_drag_operator`
- Remove keymap items that were there for the previous "hacky" solution
to apply & blend poses.

* Improve accuracy of warning when HDR display is not supported, taking into
account HDR mode on/off on Windows.
* When HDR mode is disabled on Windows, don't create a HDR swapchain. This
saves memory, and avoids a color difference on NVIDIA. That's because NVIDIA
is the only GPU we've tested that allows a HDR swapchain when HDR mode is
off, and we don't currently know the expected transforms for that case.
* Recreate swapchain when HDR mode on/off switch is detected.
* Update HDR info when window gains focus.
Note this means there is no wide gamut when Windows HDR is off, but it was
already not working. For that we may need to add support for something like
10bit VK_COLOR_SPACE_DISPLAY_P3_NONLINEAR_EXT, or whatever is commonly
available outside of HDR mode.

Use viewport navigation options in the orthographic view as well.
While the intention was to have the 3D-navigation preference only
impacting 3D views, inconsistencies between 2D/3D views tend to be
confusing for users, so use the same behavior in both.
Also expose the preference in the "3D Mouse" popup for 2D views as
this preference is used there as well.
When the `Join` operator was added to Grease Pencil v3 the behavior when
joining points was changed. The selected point would now be split from the
existing strokes and put into a new one.
This behavior is often undesirable, leading to multiple user reporting it as a

This PR adds a new mode, `Join Strokes` that behaves the same as legacy
grease pencil, and sets it as default. This PR also renames the existing modes
to `SplitAndCopy`, `SplitPoints` to better indicate the expected behavior.

Implementation of the design task #142969.
This adds the following:
- Exact GPU interpolation of curves of all types.
- Radius attribute support.
- Cyclic curve support.
- Resolution attribute support.
- New Cylinder hair shape type.
What changed:
- EEVEE doesn't compute random normals for strand hairs anymore. These are considered legacy now.
- EEVEE now have an internal shadow bias to avoid self shadowing on hair.
- Workbench Curves Strip display option is no longer flat and has better shading.
- Legacy Hair particle system evaluates radius at control points before applying additional subdivision. This now matches Cycles.
- Color Attribute Node without a name do not fetch the active color attribute anymore. This now matches Cycles.
Notes:
- This is not 100% matching the CPU implementation for interpolation (see the epsilons in the tests).
- Legacy Hair Particle points is now stored in local space after interpolation.
The new cylinder shape allows for more correct hair shading in workbench and better intersection in EEVEE.

This PR adds a slip tool in the toolbar with its own custom icon for
applying slips using the mouse. This is useful for e.g. tablets where a
keyboard is not handy and a button would be best to activate the
operator.
There is also a custom cursor that appears when hovering over valid,
slippable strips (and a "stop" icon when the strip cannot be slipped).
Alt may be used in order to ignore slipping connected strips when using
the tool, similar to selection logic. The slip tool only performs its
sole function of slipping and as such does not change the selection
state.
In the future, we can also add "slide" functionality to the same tool,
giving it multiple functions.

Implements the proposed design (with some modifications) in #135058.
## Sequencer Scene
This adds a new property called `sequencer_scene` to workspaces. This scene is used
by the video sequence editors in the current workspace for their context.
This is a first step towards "detaching" the VSE from the active scene in the window.
Each sequencer timeline editor shows the sequencer scene that is being used.
By default, when no sequencer scene is selected, the timeline and preview are empty.
Pressing the "new" button will add a new scene and assign it to the sequencer
scene for the current workspace.
## Contextual Playback
Pressing `Space` (by default) for starting the animation playback is now contextual:
depending on the context (where your mouse cursor is), the scene that is played back
might be different. E.g. with a 3D Viewport and a Sequencer open, pressing "play"
in the 3D Viewport will play the _active scene_ of the window, while pressing "play"
in the sequencer will play the _sequencer scene_.
## Time & Scene Synchronization
Additionally, this adds a toggle called "Sync Active Scene".
With the property turned on, the active scene & scene time in the window will be
synced with the time & scene of the current scene strip in the sequencer.
Note that this is _not_ bi-directional. The sequencer can change the active scene
and map time, but it's not possible the other way around since it one can have
multiple strips using the same scene (+camera, and even time!).
Currently this setting is exposed in the footer of the sequencer timeline as well
as in the workspace settings.
This allows for one of the core concepts that the story tools projects aims at: Working
in a scene (e.g. in the 3D viewport) while also working with the edit
(in the sequencer timeline).
## Some technical notes
* Undoing while playback is running will now cancel playback. This is to avoid the timer,
that points to the scene and viewlayer that are playing, to get de-synced after loading
the memfile undo step.
* When the sequencer scene is not the same as the active scene, we ensure it has
a depsgraph.
* Normally, when a `NC_SCENE` notifier points to a specific scene, the notifier is dropped
if that scene doesn't match the active one in the window. We now also check that it
doesn't match the sequencer scene in the active workspace.
* When loading older files, we need to make sure that the active workspace in a window
uses the active scene as the sequencer scene. This is to make sure that the file opens with
the same sequences open.
* Tool settings are stored per scene. To make sure the sequencer uses the tool settings for
the sequencer scene, the "context.tool_settings" and `CTX_data_tool_settings` members
are overridden in the sequence editors.
