This PR allows users to select a GPU backend.
In the system tab of the user preferences the GPU backend can be selected in the `Display Graphics` panel.
It will require a restart of Blender before the changes become effective.
During startup minimum requirements are checked. Blender will switch automatically
to OpenGL when no compatible Vulkan device could be detected. A dialog will be shown
to inform the user.
The setting of the in the `Display Graphics` panel are still overridden when blender is started
using the `--gpu-backend` option. When starting blender with `--debug-gpu` the backend
detection will print to the console.
See PR for detailed information and screenshots of the UI.
Implements #126504
Pull Request: https://projects.blender.org/blender/blender/pulls/126545
Accessing `bl_rna` for type defined in `scripts/modules/bpy_types.py`
could return their parent-classes RNA when accessed via their parent
types __subclasses__() method.
- Move sys_info into an internal module to avoid having so many
top level modules for Blender's internal functionality.
- Rename system_info sub-modules that pre-fill URL's for clarity.
- Move top-level exception handling into the operator.
- Report an error if an unexpected exception occurs.
- Use `Exception` instead of `BaseException` as there is no reason to
catch the additional exceptions.
- Remove use of sys_info from the command line example,
replace with in-lined system info.
Add Action + Action Slot selectors to various Property Editor tabs.
This follows the pattern established in
f917b60036.
Support for `CacheFile` data-blocks is not included here. That needs
some discussion, as currently its interface is part of the Modifier
stack (and thus implemented in C++ and not Python, and using a
different layout).
Since this PR is about adding to the Property Editor, some data-blocks
that have no representation there are thus excluded (like `Mask`).
Even when they could actually use an Action+Slot selector somewhere.

The new Action selector (51fd355c01) avoids the need to use
`space_data.action` in the dope sheet (that attribute was a bit of a
hack; the new Action selector was made to avoid that). It failed to take
the dope sheet's shape key mode into account properly, though. This is
now fixed.

Proportional edit works with shortcut in mask mode of image editor but
it was never exposed in UI (header). Also move pivot point along with
proportional edit property to the right of mask template.

This commit adds a python script that can collect some of the
information necessary to fill out a bug report.
The primary use case is to help users collect system information for
a bug report in the case that Blender can't open.
CMD and sh files are included to help users use the Python script.
Ref !122191
Recent fix 21b820cd33 in BPY/RNA code broke introspection code of RNA
data in i18n message extraction code.
Luckily, it actually fixes things, and allows to remove some of the ugly
hacks we had in this code, especially regarding Operators handling.
GPv3 is no longer really a experimental feature now and the
experimental option is also removed already, so it does not
make much sense keeping this branch in the UI.
Add two new operators, `anim.slot_new_for_id` and
`anim.slot_unassign_from_id`. These are used in the Action editor and
the Animation panels in the Properties editor, to respectively create a
new Action Slot for an ID and to unassign whatever slot is currently
assigned to that ID.
The latter operator also replaces the C++ operator
`anim.slot_unassign_object`, which was specifically made for the
Dopesheet header. The Python ones are generic enough to be used there
too.

In the Properties editor, add Action selectors to the Material
properties and the Camera properties.
For the Material, two Action selectors are shown: for the Material
itself and for its shader node tree. Those are separate IDs of different
types, and thus will always have separate Actions (until the Slotted
Actions are commonplace).
When the 'Slotted Actions' experimental feature is enabled, also show
the Action Slot selector underneath each Action selector.
The Animation panel in the Properties editor is (by default) always at
the bottom, just above the Custom Properties panel.

This node hashes various types into an integer. Note that hashes
cannot generally used as unique identifiers because they are not
guaranteed to be unique. It can be used to generate somewhat
stable randomness though in cases where White Noise does not
offer enough flexibility.
It uses hash functions from BLI_noise.hh. These are also used in
the White Noise node.

Previously, all errors, warnings and info messages were propagated from the node
that generates it to the top level node group. This is a good default, but may
not always be desirable. For example, someone may build a node group asset that
generates some warning that is irrelevant to the user to the asset. Now, the
asset author can selectively disable propagating warnings from that node.
Each node has a new `Warning Propagation` setting. It controls if warnings from
this node should be propagated to the parent group node. By default, everything
is propagated. One can also choose to propagate nothing, only errors or only
errors and warnings.
Note, this does not affect whether the warning is shown in the node itself, only
if the warning is propagated one level up!
Pull Request: https://projects.blender.org/blender/blender/pulls/126786
This implements the `Warning` node that allows node groups to communicate
expectations about input values to the user.
By default, the `Warning` node is only evaluated if the node group that contains
it is evaluated in any way. This is better than always evaluating it, because
that could trigger lots of unnecessary evaluation in parts of the potentially
large node tree which should be ignored. In this basic mode, the output of the
node should not be connected to anything and it must not be in a zone.
For more fine-grained control for when the `Warning` node should be evaluated,
one can use the boolean output which is just a pass-through of the `Show` input.
If this output is used, the `Warning` node will only be evaluated if its output
is used. A simple way to use it is to control a Switch node with it that e.g.
"disables" a specific output when the inputs are invalid. In this case, the
`Warning` node may also be in a zone.
The node allows the user to choose between 3 severity levels: Error, Warning and
Info. Those are the same levels that we use internally. Currently, the error and
warning mode are pretty much the same, but that may change in the future.

Add new operator `anim.slot_new_for_object`, which creates a new action
slot for the active object. Since this slot is created on the action
used by the object, it requires that this action exists and is a
layered/slotted action (which by definition includes empty actions).

When point/curves count of a `GreasePencilDrawing` is changed, prior stroke
slices are no longer valid. This is not obvious when using the `stroke()`
call since it is meant to provide a easier access to the drawing data and
did not represent the actual data layout in the drawing, hence we need an
additional note in the document to tell users to be more careful.

Add Metallic BSDF Node to the shader editor.
This node can primarily be used to create more realistic looking
metallic materials than the existing Glossy BSDF node.
This commit does not add any new closures to Cycles, it simply exposes
existing closures that were previous hard to access on their own.
- Exposes the F82 fresnel type that is currently used by the
metallic component of the Principled BSDF. Results should match
between the Metallic BSDF and Principled BSDF when using the same
settings.
- Exposes the Physical Conductor fresnel type that was previously
limited to custom OSL scripts. The Conductor fresnel type accepts
IOR and Extinction coefficients to define the appearance of the
material based off real life measurements.
EEVEE only supports the F82 fresnel type with internal code to convert
the the physical conductor inputs in to a colour format for F82,
which can lead to noticeable rendering differences with
some configurations.

Writing to the `curve_type` attribute directly is not allowed as there are other
updates needed and otherwise will result in a crash.
The fix makes sure the `curve_type` is read-only. To change the curve type,
the `grease_pencil.set_curve_type` operator has to be used for now.
For a brief moment when switching to a maximized screen full area, the
screen context is missing its `object` it seems, until the context is
properly set up again.
Prevent the 'Context' object has no attribute 'object' by just checking
if it is available

Adds the ability to connect and disconnect strips in the VSE.
- Connected strips have an icon indicating their status, and attempting
to select one connected strip selects all other connected strips in
that chain.
- If the user attempts to connect a strip that is already connected to
other strips, that strip will disconnect itself from others before
connecting to new strips.
- Preview selection also works in bulk if multiple video strips are
connected together in the timeline.
- When adding new strips from the Add menu or the File Browser, strips
from the same file are connected by default. There's an option to
turn this off in Editing > Video Sequencer user preferences.
- It is possible to individually tweak strips/handles and ignore
connections with Alt+Click.
- This shortcut overrides the old keymap item for "Linked Handle"
selection. The property still exists if people want to use that
shortcut for its old purpose.
- To make sure that connections remain valid even after duplication,
I've added a condition to `seq_new_fix_links_recursive` that also
updates connections using the `seq->tmp` var. (A note -- I've updated
the comment for this field in `DNA_sequence_types.h` because the var
is only used for duplication now. It was once present in
`select_more_less_seq__internal` to be used for linked selection but
is gone now).
- There are also functions to cut one-way links and make sure that
all strips are bidirectionally connected after duplicating.
