This adds a new "Active Camera" input geometry node, per #105761.
The node outputs the the scene's current active camera. It is available
from Input > Scene > Active Camera in the geometry nodes Add menu.
Typical usage would be to connect this node to an Object Info node to
obtain its transform. This works as expected when the camera's
transform is animated, and also when there are markers on the timeline
that change the active camera.
In order to support the aforementioned changes in the active camera,
this implementation adds depsgraph relations for all cameras referenced
by timeline markers. This eliminates the complexity of updating the
depsgraph whenever the scene switches to a different active camera,
but of course it comes at the cost of including more objects than
strictly necessary in the depsgraph for scenes that switch cameras.
Dynamically updating the depsgraph upon camera changes could be a
future improvement if there proves to be sufficient need for it.

Adds new curves support to "Draw Curve" operator. This is a direct copy
and replace of the old code to the new editors directly, with a change to
create the new data structure instead of the old one. There is no attempt
at code deduplication, since that would complicate removing the old
curve type when it comes time.
To replace the "2D curve" option a new operator property is added
for projecting to the Z=0 plane.

This de-duplicate some passes in the raytracing
pipeline and make it more ready for adoption
of arbitrary closure evaluation. This last part
means the removal of some per closure type
options.
The put in common the tile classification step
that is now done only once for all 3 closure
type. Also add some speedup to the tile
compaction phase that is now only twice
faster.
The horizon-scan setup was also de-duplicated
and run only if needed, which can save up to
0.5ms is complex scenes.
However, this moves the max-roughness and and
resolution scaling to a common parameter.
This is to be able to support arbitrary closure
evaluation where multiple closure with conflicting
parameters could be evaluated in one tracing pass.

Remove "Invert Visible" from the face sets menu, since those concepts
are no longer tied together, except for some convenience features to
toggle visibility of some face sets.
On the code side, the `SCULPT_OT_face_set_invert_visibility` operator
is replaced by `PAINT_OT_visibility_invert`. It inverts vertex visibility
instead of face visibility, which mostly has the same results, except
for multires sculpting where it no longer "downgrades" visibility to
base mesh faces.
This PR adds the drawing placement modes from GPv2.
The drawing placement defines the depth (origin, view, surface, etc.) and a plane (view, cursor, xz, etc.).
This introduces a new helper class `DrawingPlacement` that does all of the internals to find the correct projection and just exposes a simple function to project from screen space to the drawing plane/surface.
Note: Drawing on other strokes currently doesn't work, because GPv3 can't be rendered to image yet. We use the depth buffer of the grease pencil render result to find the right depth.

Currently, in weight paint mode, there is an icon for
face and vertex selection mode, but there isn't one
for the default mode where the user can select a bone
in any tool by alt clicking.
This lack of indication might lead to confusion for the users
when they are not able to select a bone by
alt clicking during weight painting.
By adding a bone selection icon when there is a pose
mode armature, we can communicate to the user that:
1. they can select a bone while the bone selection icon is active.
(when they are not in face or vertex selection mode)
2. they have forgot to select an armature when entering
weight paint mode by not showing the bone selection
icon at all when there is no pose mode armature.
When the bone selection icon is inactive,
the user can't select a bone.
(alt clicking selects face and vertex mode's respective element)
When no armature is selected when entering weight paint mode,
the bone selection icon doesn't show up indicating that the user
has forgot to select an armature.
(The user is also unable to select a bone by alt clicking.)
## Selection tool for bone selection mode
Currently, while selection tools exist for face and vertex
selection mode, one doesn't exist for the default mode
(bone selection mode). As the default mode will be getting
a clear indicator that it will function as a bone selection mode,
I added a selection tool entry for the bone selection mode.
Face and vertex selection modes has the shortcut 1 and 2,
so it seemed natural to give bone selection mode the shortcut of 3.

Related commit: 82aa300e1c / 5596f7982182aa300e1c made it so that if only linked images are used, painting
would be prohibited. But since painting in Material mode actualy paints
across all materials it could happen that one particular image is linked
whereas another image isnt. In this case, painting on the linked image
would not be prohibited.
Two issues:
- [1] logic in above commit(s) seems slightly wrong, we could still pass
the check for linked images (also no image here should also not result
in a positive check I think).
- [2] code in `project_paint_prepare_all_faces` would still work with
linked images in slots, so
-- `ProjPaintState` -> `image_tot` was incremented
-- `ProjPaintImage` was created
-- this then ends up in the undo push - and crashes on undo
So now [1] is rectified and for [2] we skip faces with associated linked
images.
In addition, slots with linked images are now also greyed out in the UI
(`VIEW3D_PT_slots_projectpaint`) to give some sort of hint. For the
future it would probably also be good to dissallow selection of such
paint slots, but that is for another commit.

When pressing `I` in the viewport, the colors of the FCurve channels were no longer set correctly.
Caused by #113504
Fix by removing the flag that determined that in the first place,
and read straight from the user preferences. Then move the code
that sets the mode on the FCurve into the function that actually creates it.
For 99% of cases the code went to the user preference flag `AUTOKEY_FLAG_XYZ2RGB`
and if that was set, the `INSERTKEY_XYZ2RGB` would be set. The only case where this
was not from the user preferences was from custom keying sets.
There was an override flag for FCurve colors on custom keying sets.
I removed that with this patch since the use case is not apparent
and custom keying sets are hardly used.

Add an "Index Switch" node which is meant as a simpler version of
the "Menu Switch" from #113445 that doesn't allow naming items
or displaying them in a dropdown, but still allows choosing between
an arbitrary number of items, unlike the regular "Switch" node.
Even when the Menu Switch is included (which should be in the
same release as this), it may still be helpful to have explicit mapping
of indices, and a fair amount of the internals can be shared anyway.

Currently we have options to transfer the paint mask, face sets, and
color attributes to the new mesh created by voxel remesh. This doesn't
make use of the generic attribute design, where it would be clearer to
transfer all attributes with the same methods. That's reflected in the
code as well-- we do duplicate work for the mask and vertex colors, for
example.
This commit replaces the transfer options with a single checkbox for
all attributes. All attribute types on all domains are transferred with
basically the same method as the "Sample Nearest" node from geometry
nodes-- they take the value from the nearest source element of the same
domain. Face corners are handled differently than before. Instead of
retrieving the mixed value of all the corners from the nearest source
vertex, the value from the nearest corner of the nearest face.
---
Some timing information, showing that when interpolating the same
data, the attribute propagation is significantly faster than before.
Edge and corner attributes would add some cost (edges more than
corners), but might not always be present.

This uses the principles outlined in
Screen Space Indirect Lighting with Visibility Bitmask
to compute local and distant diffuse lighting.
This implements it inside the ray-tracing module as a fallback when the
surface is too rough. The threshold for blending between technique is
available to the user.
The implementation first setup a radiance buffer and a view normal
buffer. These buffer are tracing resolution as the lighting quality is
less important for rough surfaces. These buffers are necessary to avoid
re-projection on a per sample basis, and finding and rotating the
surface normal.
The processing phase scans the whole screen in 2 directions and outputs
local incomming lighting from neighbor pixels and the remaining
occlusion for everything that is outside the view.
The final steps filters the result of the previous phase while applying
the occlusion on the probe radiance to have an energy conserving mix.

When animators want to key something in the viewport,
the code needs to know *which properties* should be keyed of that selected thing.
So far that was done with keying sets, and a pop-up that let's
you choose the keying set to use. You can get rid of the popup by
choosing a keying set ahead of time. But that is also not always desirable.
That pop-up is quite confusing and gives way too many options.
To simplify this process this PR adds a User Preference option to choose one or more of:
* Location
* Rotation
* Scale
* Rotation Mode
* Custom Properties
Now whenever the `I` key is pressed in the viewport,
and no keying set is enabled, it reads the preferences for which channels to insert.
# User Facing changes
* The popup will not be shown when pressing the hotkey,
but you can still explicitly use keying sets by going to the menu
* Which channels are keyed is defined by a User Preference setting under animation
* when a keying set is used explicitly, the User Preference settings are ignored

This path merges the Musgrave and Noise Texture nodes into a single
combined Noise Texture node. The reasoning is that both nodes
intrinsically do the same thing, which is the layering of Perlin noise
derivatives to produce fractal noise. So the patch de-duplicates code
and unifies the use of fractal noise for the end use.
Since the Noise node had a Distortion input and a Color output, while
the Musgrave node did not, those are now available to the Musgrave types
as new functionalities.
The Dimension input of the Musgrave node is analogous to the Roughness
input of the Noise node, so both inputs were unified to follow the same
behavior of the Roughness input, which is arguable more intuitive to
control. Similarly, the Detail input was slightly different across both
nodes, since the Noise node evaluated one extra layer of noise. This was
also unified to follow the behavior of the Noise node.
The patch, coincidentally fixes an unreported bug causing repeated
output for certain noise types and another floating precision bug
#112180.
The versioning code implemented with this patch ensures backward
compatibility for both the Musgrave and Noise Texture nodes. When
opening older Blender files in Blender 4.1 the output of both nodes are
guaranteed to always be exactly identical to that of Blender files
created before the nodes were merged in all cases.
Forward compatibility with Blender 4.0 is implemented by #114236.
Forward compatibility with Blender 3.6 LTS is implemented by #115015.
