This node is a field input that outputs a separate index for each mesh island.
The indices are based on the order of the lowest-numbered vertex in each island.

This allows real world cameras to be modeled by specifying the coordinates of a
4th degree polynomial that relates a pixels distance (in mm) from the optical
center on the sensor to the angle (in radians) of the world ray that is
projected onto that pixel.
This is available as part of the panoramic lens type, however it can also be
used to model lens distortions in projective cameras for example.

This node calculates the dual of the input mesh. This means that faces
get replaced with vertices and vertices with faces. In principle this
only makes sense when the mesh in manifold, but there is an option to
keep the (non-manifold) boundaries of the mesh intact.
Attributes are propagated:
- Point domain goes to face domain and vice versa
- Edge domain and Face corner domain gets mapped to itself
Because of the duality, when the mesh is manifold, the attributes get
mapped to themselves when applying the node twice.
Thanks to Leul Mulugeta (@Leul) for help with the
ascii diagrams in the code comments.
Note that this does not work well with some non-manifold geometry,
like an edge connected to more than 2 faces, or a vertex connected to
only two faces, while not being in the boundary. This is because there
is no good way to define the dual at some of those points. This type
of non-manifold vertices are just removed for this reason.

The datatypes support the following operators:
Float, Int: <, >, <=, >=, ==, !=
String: ==, !=
Color: ==, !=, lighter, darker
(using rgb_to_grayscale value as the brightness value)
Vector Supports 5 comparison modes for: ==, !=, <, >, <=, >=
Average: The average of the components of the vectors are compared.
Dot Product: The dot product of the vectors are compared.
Direction: The angle between the vectors is compared to an angle
Element-wise: The individual components of the vectors are compared.

When a manual frame range is set, allow marking an action as having
Cyclic Animation. This does not affect how the action is evaluated,
but the Cycle-Aware Keying option will automatically make any newly
added F-Curves cyclic. This allows using the option from the start
to build the cycle, rather than only for tweaking an existing loop.
The curves are made cyclic when they have only one key, either
after inserting the first key, or before adding the second one.
The latter case avoids the need to manually make the first added
curve cyclic after marking a newly added action cyclic.

Some operations, e.g. adding a new action strip to NLA, require
knowing the active frame range of an action. However, currently it
can only be deduced by scanning the keyframes of the curves within
it. This is not ideal if e.g. curves are staggered for overlap.
As suggested by Nathan Vegdahl in comments to T54724, this patch adds
Action properties that allow manually specifying its active frame range.
The settings are exposed via a panel in the Dopesheet and Action Editor.
When enabled, the range is highlighted in the background using a striped
fill to distinguish it from the solid filled regular playback range.
When set, the frame range is used when adding or updating NLA tracks,
and by add-ons using `Action.frame_range`, e.g. FBX exporter.

In rBdcdbaf89bd11, I introduced a new operator
(`file.asset_library_refresh()`) to handle Asset Browser refreshing more
separate from File Browser refreshing. However, there already was
`asset.asset_list_refresh()`, which at this point only works for asset
view templates, but was intended to cover the Asset Browser case in
future too. This would happen once the Asset Browser uses the asset list
design of the asset view template.
So rather than having two operators for refreshing asset library data,
have one that just handles both cases, until they converge into one.
This avoids changes to the Python API in future (deprecating/changing
operators).

This feature has been desired for some time:
- https://rightclickselect.com/p/ui/Tqbbbc/allow-navigating-while-transforming (See comments);
- D1583;
- T37427;
In short, blocking navigation during transform limits the user to move the object only to visible areas within the screen and hinders the allocation of objects within closed meshes.
The node editor is also impaired because some nodes are far between them and the connectors are too small.
The only disadvantage of this patch (as I see it) is the conflict with the existing key map:
MIDDLEMOUSE:
- enable axis constrain in 3D view;
WHEELDOWNMOUSE, WHEELUPMOUSE, PAGEUPKEY, PAGEDOWNKEY:
- change the threshold of the proportional edit;
So the patch solution was to change these keymaps:
- MIDDLEMOUSE to Alt+MIDDLEMOUSE;
- WHEELDOWNMOUSE, WHEELUPMOUSE, PAGEUPKEY, PAGEDOWNKEY to Alt+(corresponding key);
When you use this new keymap for the first time in the proportional edit, it may seem strange due to the custom of using it (both in View2D and View3D).
But quickly the user gets used to it.
Alternatively we can add an option to the user preferences ([] Allow navigating while transforming). (I'm not much fan of this option).
The patch was done on branch2.8. But maybe it's a good idea to apply it to 2.79

This patch implements part of what was stated in {T66484}, with respect to `Base Point`.
## Introduction
The snapping feature of the transform tools has a variety of applications:
- Organization of nodes.
- Positioning of frames in precise time units.
- Retopology with snap to face
- Creation of armatures with bone positioning through the snap to volume
- Precise positioning of 3D or 2D objects in the surrounding geometry (CAD modeling)
The goal of this document is to make it more powerful for precision modeling and still supporting the old use cases without extra complexity.
The main topic addressed here is the introduction of a **interactive mode for setting a snap source** (See terminology).
## Terminology
* **Snap Source**: 3d coordinate * we want to snap from. (Currently defined by the `Snap With` options: `Closest`, `Center`, `Median` and `Active`).
* **Snap Target**: 3d coordinate* we want to snap to. (Vertices, Edges, Faces, Grid...)
## Interactive Mode for Editing a Snap Source
Currently the fixed snap point can only be obtained through the `Snap With` options. So it's a little tricky for the user to define a snap source point having so much geometry on an object.
Because of this, the user needs to resort to impractical solutions to get a point in the geometry.
See example of an impractical use:
{F11714181, layout=left, width=960, alt="The user used the cursor (which can be snapped) to choose the snap origin point."}
The user used the cursor (which can be snapped) to choose the snap source point.
While it is possible to work around this current limitation, it is important to reduce the number of steps and allow the user to set a snap source point through an optional interactive mode during a transformation.
The proposed solution is to be able to move the current snap source point through a modal modifier activated with a key (eg. B).
The snap source point can thus "snap" to the elements in the scene (vertex, mid-edge, Lamp, …) during this mode.
{F9122814, layout=left, width=960, alt="Base Point Snap, example of transform operation via the shortcut (not the tool). After pressing g and the snap base change shortcut (e.g., shift + ctrl) the user set the base point. The base point is then visible until the end of the operation. The z axis constrains the final position."}
## Implementation Details
- The feature will only be available in 3D View.
- The feature will only be available for `Move`, `Rotate` and `Scale` transform modes.
- The snap source editing will be enabled with a single click on the modifier key (B).
- Having a snap point indicated, the new snap origin point will be confirmed with the same buttons that confirms the transformation (but the transformation will not be concluded).
- The snap source editing can be canceled with the same key that activated it (B).
- If the transformation is done with "release_confirm" (common for gizmos), the new feature cannot be enabled.
- During the transformation, when enabling the feature, if the snap option is turned off in the scene, the snap will be forced on throughout the rest of the transformation (unless interactive mode is canceled).
- During a transformation, if no snap target is set for an element in the scene (Vertex, Grid...), the snap targets to geometry Vertex, Edge, Face, Center of Edge and Perpendicular of Edge will be set automatically.
- Snap cannot be turned off during the snap source editing.
- Constraint or similar modification features will not be available during the snap source editing.
- Text input will not be available during the snap source editing.
- When adding multiple snap points (A) the new prone snap source point will be indicated with an "X" drawing.
