Addresses #146305.
Ever since moving to the "sequencer scene" paradigm, attempting to
render an image or animation when a sequencer with strips is present
often seems to outright ignore the sequencer in most cases. This is
because the sequencer scene usually differs from the active scene (which
is the true render target), so one must first switch their active scene
to the sequencer scene before rendering. This is confusing and
seems like a regression in behavior. To improve clarity, this patch does
the following:
When a sequencer scene with at least one strip (and the sequencer step
enabled in the pipeline) exists in the current workspace, new options
"Render Sequencer Image" and "Render Sequencer Animation" appear. These
options may be invoked by alt-F12 and ctrl-alt-F12, respectively.
Additionally, if such a valid sequencer scene is the same as the active
scene, then only the regular render options are listed, since in this
case they are identical to the sequencer render operators, meaning F12
still works predictably.
To switch back and forth between sequencer and main scene render
outputs, a new toggle has been added to the image editor to "Show
Sequencer Scene" output. This button only appears for the render result
if there is a valid sequencer scene that differs from the active scene.

Adds a new operator that jumps time by a given number of frames or seconds, forward or backward.
Surprisingly, it was lacking in Blender, and prompted many users (including me) to create extensions.
This PR adds two properties: `time_jump_unit` for choosing whether to jump by frames or seconds
and `time_jump_delta` property that defines by how many frames or seconds the operator should jump,
as well as an actual operator that changes the current frame (`screen.time_jump`).
`time_jump_delta` is a float that gives users the ability to jump by half a second, for example, or by subframes.
Default is set to 1 second, which translates to as many frames jump as frame rate / frame base.
The operator is intentionally not bound by frame range, and can go in negative frames as well.
This is very important because it's extremely common to set frame range to the current workload,
but wish to see animation beyond that.
Operators are added in the new footer for animation editors alongside with pop-up menu where
properties can be changed.
Shortcuts are also added: Ctrl+Left/Right Arrow, which was surprisingly free in Blender.
Now timeline controls are:
- **Right Arrow**: Next Frame
- **Ctrl + Right Arrow**: Jump Forward (by default also Next Second)
- **Shift + Right Arrow**: Jump to End

This PR Updates the default colors of the Curve Handle types,
to increase readability and contrast.
Each color more different from each other to not be confusing.
Logic for the new colors:
* Purple/Dark blue is used for the `Vector` type to match the header
and sockets of Vector nodes.
* Red is used for `Auto` to show that they're locked and can't be
changed without converting the type.
* Pink/Salmon color is used for `Auto-Clamped` to be similar to `Auto`
while still being distinct.
* The remaining colors are chosen to be visually distinct from the
other colors.
This also fixes a problem caused by 1067112c11 (#145360) where
Free handle were left fully black. These black handles are extremely
hard to use with Grease Pencil objects, because Grease Pencil strokes
often are black. Because the `Free` handle selected color is also black,
handles do not show if they are selected.

The operator moves selected UVs, using the num-pad for directional keys:

- Dynamic grid unit (CTRL + NUMPAD KEY)
- Pixel unit (SHIFT + NUMPAD KEY)

Currently, attempting to split connected strips that are not both
selected means that only one of the strips are affected. This violates
the "connected" principle, so this PR makes the split operator propagate
the split to connected strips by default. Holding alt returns old
behavior (ignores connections), similar to selection logic.
Pull Request: https://projects.blender.org/blender/blender/pulls/146380
The issue was that the used operator just took the active node into account.
However, clicking in empty space does not make the active node inactive.
Therefore, sometimes clicking on empty space would sometimes remove enter the
last selected group node. Furthermore, double clicking on other nodes may also
trigger exiting the current group.
This is fixed by introducing a new operator that explicitly checks what node is
hovered.
Pull Request: https://projects.blender.org/blender/blender/pulls/147053
This adds a new operator which can join multiple nodes together. Currently, it
only supports joining Group Input nodes. However, in the future it could be
extended to join e.g. Bake and Capture Attribute nodes.
This uses the recently freed up ctrl+J shortcut for this functionality, which
feels natural to me.
The implementation is fairly straight forward. The main tricky aspect is
sometimes the nodes can't be joined when that would result in two sockets being
linked to each other twice. In this case, the a separate Group Input node is
kept.
The selected nodes are merged into the active node (in case the active node is
part of the selection, otherwise there is a fallback).

In 3D Viewport theme settings there is "Active Spline" property, which behaves weirdly.
Color of that property is multiplied to color of curve handles. Even though it says active,
it's multiplied in selected and unselected states, for all curves all the time.
That doesn't make much sense, has no real value, and ends up only causing confusion.
Having this property on anything but pure black means that whatever colors you choose
for curve handles in Preferences isn't actually what you're getting them. If color is set to
high-saturation color it completely washes away all colors and makes it difficult to differentiate
between handle types.
I think there is no reason for this property to exist, so this PR just removes that property.

Nodes have many indicators in their header: whether they have a
preview, warnings, whether they are a node group, plus potentially
more such as if the library is linked/overriden or packed data.
Of all indicators, whether the node is a node group or not is often not
so relevant (especially when many nodes will be just node group assets)
so having an icon takes away precious real estate for other indicators.
Draw the node shape slightly different. A subtle "stack" of nodes
behind Node Groups indicate this is more than just one node.
The stack is only drawn at a certain zoom.
It is now possible to double-click a node group to enter.
It also makes some more room for the node label, since the node group
icon in the header is no longer needed.
Plus a few visual tweaks and fixes for broken/non-valid nodes.
See PR for details and screenshots.

3D Viewport and Image Editor had theme colors for paint curve handle and pivot.
Paint curves are one of the stroke methods for brushes, and are generally not
widely used. To simplify theming it's best to remove those four properties and
use other shared colors instead.
We could use common curve colors for them, but they don't have point color
and handle point color is black, so we would need to add one more property
anyway and it would look bad as well.
Instead, use gizmo primary and secondary colors. Technically, paint curves
can be treated as gizmos, because they're interactive widgets in the viewport.

Implement a native method to swap between different node and zone types.
This implementation repurposes the existing menu definitions as base
classes, from which both an "Add" and a "Swap" version would be generated
from. This allows both menus to have the same layout, but use their own
operators for handling the different node/zone types.
In this PR, support for all node editors has been implemented.
Invoking the menu is currently bound to `Shift + S`, same as the old
implementation in Node Wrangler. Since "Swap" is implemented as a
regular menu, features that menus already have such as type-to-search
and adding to Quick Favorites don't require any extra caveats to
consider.

Mesh faces have a separate theme color for selected dots (1px dot in the center of the face),
in both the 3D Viewport and the Image Editor.
I don't think there is any justification for why that 1 pixel has to be a different color from rest
of the active face. Even if result isn't satisfying, we should be tweaking Face Selected color
for this purpose. 1 pixel doesn't deserve its own theme setting.
This PR removes property from both editors, and instead uses "Face Selected" color with alpha
hardcoded to 1 (removed properties didn't have alpha). Also note that dot is still visible in 3D viewport
because Face Selected color is different from Face Mode Selected color, which is used for faces
when dots are drawn.
There are no visual changes in default themes.

- Channels looked different in Dope Sheet and Graph Editor. In the former,
they were same color as the background, so only labels and icons were visible,
in the latter they had a darker color, so their outline was visible. We need to pick
which design we go for now that they're combined. I chose color from Graph
Editor for now, with alpha from Dope Sheet, since only that editor uses alpha.
---
There is a confusion with names of channel colors. In 4.5 there is:
- - "Channel" (singular, blue color) which refers to objects, actions,
and action slots that hold/combine channels.
- - "Channels" (plural, black color) which refers to individual channels.
This goes against how we name things. In theme, especially, we refer to object
colors as "Object", singular, not Objects, plular. Same goes for all elements except
this one, where individual elements are referred in plural.
To lessen the confusion, and also avoid unnecessary breaking changes in the
future (in case we want to rename blue things, which seems likely), in this PR
I swap those names. Main reason is that black color marks individual channels,
so it should be singular, and blue colors are combination of many channels,
so they should be plural. Otherwise even talking about them is awkward.
Note that renaming isn't a breaking change, because we already "broke" them
by moving them to common path from individual editors.

Continuing recent attempts to combine theme settings
and reduce complexity. part of #140360
This PR adds new root panel in theme called "Regions" which for now
includes two subpanels:
# Asset Shelf
This is just moving asset shelf from root to regions, where
it's more appropriate and less noisy.
No functional changes. (alternative to #144267)
# Channels
Previously known as "Theme Space List", or "Source List",
but in user interface we refer this region as "Channels".
This region is shared by all animation/video editors, and each had
a separate panel for theme properties. Now they're combined, and all
editors follow settings defined in Regions -> Channels.
Additionally, "Source List Title" property, which was never used is removed.
Properties are also renamed to be more intuitive and shorter.
# Toolbar / Sidebar
Previously was registered separately on every single editor. This allowed
for some extra customization, but in 5.0 need for this is reduced very much,
because elements drawn in those regions (tabs & tools) are also generalized,
so it makes sense to want same background color for them as well.

Always enforce tiling of some size, up to the 8k tile size.
Rendering very big images without tiles have a lot of challenges.
While solving those challenges is not impossible, it does not seem to
be a practical time investment.
The internals of the way how Cycles work, including Cycles Standalone
is not affected by this change.
A possible downside is that path guiding might not work exactly how one
would expect it to due to lack of information sharing across multiple
tiles. This is something that never worked nicely, and camera animation
and border render has the same issues, so it is not considered a stopper
for this change.

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.

- 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

`TH_LONGKEY` and `TH_LONGKEY_SELECT`.

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.

This PR adds a slip tool in the toolbar with its own custom icon for

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.

This adds the `Pen` tool to Grease Pencil Edit Mode.
With the pen tool you can:
- Extrude points by `Left Click`.
- Move the handles by dragging the mouse.
- Snap handles to 45 degree increments with `Shift`.
- Cycle through the handle types by `Double Clicking`.
- Add new point on segments by `Ctrl Clicking`.
- Remove existing point by `Ctrl Clicking`.
- Close a curve by clicking on one end while having the other selected.
- Move existing segment by clicking and dragging on the edge.
- Move points by clicking and dragging the mouse.
Some changes have been made compared to the legacy
curve object's pen tool:
- `Angle locking` with `Alt` was replaced with `Angle Snapping`
using `Shift`. This was done to match the behavior of Grease Pencil
primitive tools.
- `Move Entire Point` was changed from the `Space` key to `Alt`. This
was done because some laptops can't move the mouse while
`Space` is held.
- `Link Handles` and `Free Align Toggle` were not implemented.
- `Toggle Vector` and `Close Spline Method` were removed.
- `Close Spline` was removed and set to always be true.
- `Extrude Handle` type was removed as a option and was replaced
by the `shift` modifier key when clicking.
- Newly created points are placed on the drawing plane, instead of
the view plane.
When a new curve is created, the material will be the active material
and the radius will be set from the `radius` property.
Note: This tool is added to edit mode because it uses handle selection
and bézier overlays which currently don't exist in draw mode.
A future PR will implement a draw mode version.

Duplicating a strip that references an ID like the scene strip would not

IDs referenced by the strip. Currently this only affects `Scene`,
`MovieClip`, and `Mask` strips.
* `Alt + D` ("duplicate linked"): Duplicate the strip, but reference the
same IDs. This is the current behavior in `main`.

User Visible Changes:
- "Current Frame" is renamed to "Playhead". It was general sentiment among
Anim and UI modules to rename this everywhere after "Playhead Snapping" was
added, and this is first step towards that. Name is more recognizable and it's
clear it refers to UI element, rather than something as generic as "current frame".
- Channel, Sub-channel, Channel Group, and Active Channel Group colors in
Dope Sheet had alpha, but ones in Graph and NLA editors didn't. New common
property is used for all three of them and has alpha, meaning two editors gain
alpha as well, but they don't use alpha, still only Dope Sheet does.
- Channel and Sub-channel had different color in NLA and didn't match Dope Sheet
and Graph Editor, now since it's shared it has same color, which is a visual change
(slighlty lighter blue).
