The new theme setting for the dope sheet (timeline) allows changing the
color of the bar that shows which frames are cached/baked. The
invalid/cached/baked status is differentiated by hardcoded transparency
values. In theory, those could be separate theme settings though.

This adds support for building simulations with geometry nodes. A new
`Simulation Input` and `Simulation Output` node allow maintaining a
simulation state across multiple frames. Together these two nodes form
a `simulation zone` which contains all the nodes that update the simulation
state from one frame to the next.
A new simulation zone can be added via the menu
(`Simulation > Simulation Zone`) or with the node add search.
The simulation state contains a geometry by default. However, it is possible
to add multiple geometry sockets as well as other socket types. Currently,
field inputs are evaluated and stored for the preceding geometry socket in
the order that the sockets are shown. Simulation state items can be added
by linking one of the empty sockets to something else. In the sidebar, there
is a new panel that allows adding, removing and reordering these sockets.
The simulation nodes behave as follows:
* On the first frame, the inputs of the `Simulation Input` node are evaluated
to initialize the simulation state. In later frames these sockets are not
evaluated anymore. The `Delta Time` at the first frame is zero, but the
simulation zone is still evaluated.
* On every next frame, the `Simulation Input` node outputs the simulation
state of the previous frame. Nodes in the simulation zone can edit that
data in arbitrary ways, also taking into account the `Delta Time`. The new
simulation state has to be passed to the `Simulation Output` node where it
is cached and forwarded.
* On a frame that is already cached or baked, the nodes in the simulation
zone are not evaluated, because the `Simulation Output` node can return
the previously cached data directly.
It is not allowed to connect sockets from inside the simulation zone to the
outside without going through the `Simulation Output` node. This is a necessary
restriction to make caching and sub-frame interpolation work. Links can go into
the simulation zone without problems though.
Anonymous attributes are not propagated by the simulation nodes unless they
are explicitly stored in the simulation state. This is unfortunate, but
currently there is no practical and reliable alternative. The core problem
is detecting which anonymous attributes will be required for the simulation
and afterwards. While we can detect this for the current evaluation, we can't
look into the future in time to see what data will be necessary. We intend to
make it easier to explicitly pass data through a simulation in the future,
even if the simulation is in a nested node group.
There is a new `Simulation Nodes` panel in the physics tab in the properties
editor. It allows baking all simulation zones on the selected objects. The
baking options are intentially kept at a minimum for this MVP. More features
for simulation baking as well as baking in general can be expected to be added
separately.
All baked data is stored on disk in a folder next to the .blend file. #106937
describes how baking is implemented in more detail. Volumes can not be baked
yet and materials are lost during baking for now. Packing the baked data into
the .blend file is not yet supported.
The timeline indicates which frames are currently cached, baked or cached but
invalidated by user-changes.
Simulation input and output nodes are internally linked together by their
`bNode.identifier` which stays the same even if the node name changes. They
are generally added and removed together. However, there are still cases where
"dangling" simulation nodes can be created currently. Those generally don't
cause harm, but would be nice to avoid this in more cases in the future.

Pull Request: https://projects.blender.org/blender/blender/pulls/104924
This patch adds several tools and options to the weight paint mode of Grease Pencil.
* Blur tool: smooths out vertex weights, by calculating a gaussian blur of adjacent vertices.
* Average tool: painting the average weight from all weights under the brush.
* Smear tool: smudges weights by grabbing the weights under the brush and 'dragging' them.
* With the + and - icons in the toolbar, the user can easily switch between adding and subtracting weight while drawing weights.
* With shortcut `D` you can toggle between these two.
* The auto-normalize options ensures that all bone-deforming vertex groups add up to 1.0 while weight painting.
* With `Ctrl-F` a radial control for weight is invoked (in addition to the radial controls for brush size and strength).
* With `Ctrl-RMB` the user can sample the weight. This sets the brush Weight from the weight under the cursor.
* When painting weights in vertex groups for bones, the user can quickly switch to another vertex group by clicking on a bone with `Ctrl-LMB`.
For this to work, follow these steps:
* Select the armature and switch to Pose Mode.
* Select your Grease Pencil object and switch immediately to Weight Paint Mode.
* Select a bone in the armature with `Ctrl-LMB`. The corresponding vertex group is automatically activated.

Makes it possible to select multiple custom script directories in Preferences >
File Paths, replacing the single Scripts path option. Each of these directories
supports the regular script directory layout with a startup file (or files?),
add-ons, modules and presets.
When installing an add-on, the script directory can be chosen.
NOTE: Deprecates the `bpy.types.PreferencesFilePaths.script_directory`
property, and replaces `bpy.utils.script_path_pref` with
`bpy.utils.script_paths_pref`.

The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
Increase the default value for the maximum number of recently-opened
files from 10 to 20. Also change the user's preference on version bump
to this new value if their current value is exactly the old default.

Move two settings that were previously in the "View" menu of the Graph Editor into User Preferences.
It has been mentioned in the meeting by Luciano Muñoz Sessarego that it would be good to move that to the preferences so you can set it once and then forget about it.
The Settings moved are:
Only Selected Curve Keyframes
Use High Quality Display

Previously [D16255](https://developer.blender.org/D16255)
There is no option to adjust the edge_width like there is in the preferences for vertex_size and face_dot_size.
I only added the option for 3DView and UV/Image Editor, and limited both to a max size of 5 pixel, since the edges do not look very nice with too high values.
In the UV Editor only, there are always black outlines on the edges, I could not find a way to reduce the increasing thickness of these black outlines.
The default edge_width of 1 pixel:
Here the edge_width with a falue of 3:
And here the visible increase of the dark border of the edges and their overlap (even at the maxed size of 5):
Lastly for the 3DView the max edge_width of 5 looks like this:

This commit implements described in the #104573.
The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).
This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.
This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale
This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.
Running `make update` will initialize the local checkout to the changed
repository configuration.
Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).

After rBdb87e2a638f9, two contexts were missing:
- VirtualReality, to be used in an add-on
- Constraint, used in the constraints UI
The latter was actually used without being added, which caused errors.
It was reverted in rB31a640027982.
This is a revert of a revert, because the initial revert is only
supposed to be in the release branch.
This reverts commit 3eed00dc546b5930b255572901915ccbc26c0e69.
This reverts commit 19222627c6b57df77d3bc9ae60d7850ab7e23abb.
Something went wrong here, seems like this commit merged the main branch
into the release branch, which should never be done.
Currently Metal is more stable then the OpenGL backend on apple
devices. Also the Metal backend supports more features then the
OpenGL backend. For example the viewport compositor and rendering
of production files.
This has been validated with users and studios.
This patch will default to the Metal backend when starting
Blender 3.5 for the first time or when loading factory startup. It
is still possible to switch to OpenGL via the user preferences.
It will not automatically select the Metal backend when there is
already user preferences available for Blender 3.5.
No design or functional changes. Just rename the layers for the last
two icons that were added so that they follow the naming pattern.
Also, update the layer order for another icon (was not alphabetic).

When animating it is often useful to frame the Graph Editor/Dope Sheet to whatever frames are in a given channel.
This patch adds the option to frame on selected channels OR frame on whatever channel is under the cursor.
If a preview range is set it will only focus on keys in that range.
Supports FCurve and keyframe data
Frame to selected is called with
* Right click in the channel section -> Frame Selected Channels
* or in Channel → Frame Selected Channels
* or hitting . on the numpad
Frame to channel under cursor is done with
ALT + Middle Mouse Button

* Fix#92539: Hard to read the breadcrumbs.
* Fix View Item active, hover, and text color (e.g. count numbers in the
Spreadsheet were almost unreadable).
* Fix mismatching node type colors with the default theme.
Blender Light is meant to be simply a brighter version of the default,
so screenshots and tutorials can be followed with both themes.
* Use the same outline color for widgets, so they match when aligned in a row.
* Make panels standout (not fully transparent), like in the default theme.
