These nodes allow accessing and changing the stable/random ID used
for motion blur with instances and stable randomness.
Since rB40c3b8836b7a, the stable ID is a built-in attribute, so to be
consistent and allow changing it in the node tree like other built-in
attributes, it has get and set nodes.
Knife angle measurements were mis-aligned if a cut point was in space.
Specifically, the arc drawing would not match with the cut line.
Fixed by removing a correction for kcd->prev.cage.
This correction was originally added for panning with measurements to work.
In hindsight it is not needed and only introduces issues like this.
We already show a message when showing an asset library whose path can't be
found on disk. The red text was making it look like some fatal error happened.
And the message could be a bit more useful generally.
So this removes the red color of the text, (arguably) improves the text and
adds a button as shortcut to open the Preferences with the asset library
settings.

Renames the operator from "Show Preferences" to "Open Preferences...". "Open"
is more clear than "Show" (since they could be shown in-place). "..." is
usually used in Blender to indicate that a new Window or popup will be opened.
Note that vanilla Blender doesn't actually show this name anywhere, so this
change shouldn't be visible. That may change, see D12894.
Feedback was that "Default" is a bit of a weird name, so switching it to "User
Library". Added versioning code which won't be entirely bullet proof (e.g. will
also rename libraries named "Default" by the user), but it doesn't have to be.
Addresses T90298.
The call to `attribute_try_get_for_output` does some cache invalidation
internally. Under some circumstances the call to `position_evaluator.evaluate()`
recomputed the caches (e.g. when the Normal node was used, the evaluated
handle positions cache on curves were updated). After the positions have
been updated in the Set Position node, the cache was not invalidated again.,
leading to incorrect rendering.
The proper solution will be to do the cache invalidation in `OutputAttribute.save()`
again. That is a bit more involved though. For now just reorder the code a bit
to do the cache invalidation after the field has been computed.
There is a follow up task: T92509.
The location of a linked object isn't editable, or at least it will be reset
when reloading the file. So the drag & drop shouldn't even pretend like this
would work, so disable the snapping of the object and the bounding-box to show
the snapped object location while dragging.
When the Asset Browser import type was set to "Link", after dragging in an
object asset the object wouldn't actually appear in the viewport. Do the same
depsgraph tagging (and TODO comment) as the `OBJECT_OT_add_named` operator,
which does similar things.
This patch changes how nodes look visually, in an attempt to fix a number of issues:
* The header background is currently drawn using a theme color fully opaque, this limits the colors we can use because the node name/label is drawn on top.
* Hard-coded transparency makes nodes hard to read. The node backdrop already has alpha so if the user wants it they can set it. This patch uses alpha from the theme.
* Better muted status indicator, instead of simply making everything transparent and the wires inside red, draw a red outline around the node, darken the header and backdrop.
* On muted nodes, display wires behind the backdrop to not interfere with text/widgets inside the node.
Nodes:
* Darken header to improve readability of node label.
* Draw a line under the header
* Thicker outline.
* Do not hard-code transparency on nodes, use the theme's node backdrop alpha component.
* Use angle icon instead of triangle (to be consistent with the [[ https://developer.blender.org/D12814 | changes ]] to panels)
Style adjustment to sockets drawing:
* Do not hard-code the socket outline color to black, use `TH_WIRE` instead
* Do not use `TH_TEXT_HI` for selected sockets, use `TH_ACTIVE` (active node outline)
* Do not draw sockets background transparent on muted nodes.
* Thicker outline to help contrast and readability

Instance IDs serve no purpose for rendering when they aren't stable from
one frame to the next, and if the index is used in the end anyway, there
is no point in storing a vector of IDs and copying it around.
This commit exposes the `id` attribute on the instances component,
makes it optional-- only generated by default with the distribute points
on faces node.
Since the string to curves node only added the index as each instance's
ID, I removed it. This means that it would be necessary to add the ID
data manually if the initial index actually helps (when deleting only
certain characters, for example).

Now that object assets are no longer considered experimental, the Assets
submenu can always be shown (regardless of the Extended Asset Browser
experimental feature).
The two blocking issues for object assets are addressed, see T92111 and T90198.
So now, objects can be marked as assets and be used in the Asset Browser.
`ED_fileselect_activate_by_id()` activates an asset (i.e. marks it as
the active asset in the asset browser). To avoid an "active but not
selected" state, it also selects it.
Before this commit, the function would also deselect all other assets,
but that's considered doing too much. If deselection is required, the
`ED_fileselect_deselect_all()` function can be called.
Manifest Task: T92152
In the 3D Viewport, add an "Assets" submenu to the Objects menu, for the
same operators as available in the outliner: Mark as Asset, Clear Asset,
Clear Asset (Set Fake User).
Since object assets are still considered experimental, the menu is only
shown when the Extended Asset Browser experimental feature is enabled.
There's now a message displayed in red next to the cursor explaining that only
assets from the current file can be moved between catalogs.
The previous commit prepared this.
A tree-view item's drop controller can now return a message for the user
explaining why dropping isn't possible with the dropped data. This is then
displayed in red text next to the cursor.
This isn't actually used yet, the follow up commit will do that.
Make it possible to run `ASSET_OT_mark` and `ASSET_OT_clear` operators from
the 3D Viewport. There is no menu entry, just compatibility with pressing
F3 and executing the operators from the operator search.
Refactor `view3d_context()` to use early `return`s instead of a bundle of
`if`/`else if`/`else`, some of which had `return`s and some not.
No functional changes.
`view3d_context()` would return `-1` ("found but not available") when
fetching the context dir. This is incorrect; it should return 1 ("ok").
This is a semantic change in preparation of further cleanup of the code.
This adds generic attribute rendering support for meshes for Eevee and
Workbench. Each attribute is stored inside of the `MeshBufferList` as a
separate VBO, with a maximum of `GPU_MAX_ATTR` VBOs for consistency with
the GPU shader compilation code.
Since `DRW_MeshCDMask` is not general enough, attribute requests are
stored in new `DRW_AttributeRequest` structures inside of a convenient
`DRW_MeshAttributes` structure. The latter is used in a similar manner
as `DRW_MeshCDMask`, with the `MeshBatchCache` keeping track of needed,
used, and used-over-time attributes. Again, `GPU_MAX_ATTR` is used in
`DRW_MeshAttributes` to prevent too many attributes being used.
To ensure thread-safety when updating the used attributes list, a mutex
is added to the Mesh runtime. This mutex will also be used in the future
for other things when other part of the rendre pre-processing are multi-threaded.
`GPU_BATCH_VBO_MAX_LEN` was increased to 16 in order to accommodate for
this design.
Since `CD_PROP_COLOR` are a valid attribute type, sculpt vertex colors
are now handled using this system to avoid to complicate things. In the
future regular vertex colors will also use this. From this change, bit
operations for DRW_MeshCDMask are now using uint32_t (to match the
representation now used by the compiler).
Due to the difference in behavior for implicit type conversion for scalar types
between OpenGL and what users expect (a scalar `s` is converted to
`vec4(s, 0, 0, 1)` by OpenGL, vs. `vec4(s, s, s, 1)` in Blender's various node graphs) ,
all scalar types are using a float3 internally for now, which increases memory usage.
This will be resolved during or after the EEVEE rewrite as properly handling
this involves much deeper changes.

In future use cases, a volume can contain many grids that represent the
density information. In this case, it's better if the volume to mesh node
creates a mesh based on all of the grids in the volume.
This is also a benefit to share-ability, since one doesn't have to
specify the grid name in the node. Instead, in the future we can have
a way to split particular grids into separate volumes, if only one
grid should be considered.
The code changes are relatively simple:
- Move the old volume to mesh node to the legacy folder.
- Run the volume to mesh node on all instance geometry, like elsewhere.
- Make the blenkernel's volume to mesh API a bit more specific.

When dragging an object in non-object mode into a 3D View, there will now be
red text explaining that this is only possible in object mode.
The previous commit enabled this.
* Allow operators to show a "disabled hint" in red text explaining why dropping
at the current location and in current context doesn't work. Should greatly
help users to understand what's the problem.
* Show a "stop" cursor when dropping isn't possible, like it's common on OSes.

This patch upgrades node editor breadcrumbs to have slightly more
visual weight, to including the base path of object/modifier/world,
etc, have more visually pleasing spacing, and contain icons.
In the code, a generic "context path" is added to interface code.
The idea is that this could be used to draw other breadcrumbs in areas
like the property editor or the spreadsheet, and features could be added
to all of those areas at the same time.
Ideally we would be able to control the color of the breadcrumbs with a
specific theme color, but since they are drawn with the regular layout
system, that is not easily possible.
