7e3e4751b5 UI: Fix count on node editor/group header when fake user
The number of node groups was including the fake user count.
I was ignoring the Fake User, and how it affects the id->us count.

This problem was present since the initial commit: 84825e4ed2.

84825e4ed2 UI: Icon number indicator for data-blocks
Adds the possibility of having a little number on top of icons.

At the moment this is used for:
* Outliner
* Node Editor bread-crumb
* Node Group node header

For the outliner there is almost no functional change. It is mostly a refactor
to handle the indicators as part of the icon shader instead of the outliner
draw code. (note that this was already recently changed in a5d3b648e3).

The difference is that now we use rounded border rectangle instead of
circles, and we can go up to 999 elements.

So for the outliner this shows the number of collapsed elements of a
certain type (e.g., mesh objects inside a collapsed collection).

For the node editors is being used to show the use count for the data-block.
This is important for the node editor, so users know whether the node-group
they are editing (or are about to edit) is used elsewhere. This is
particularly important when the Node Options are hidden, which is the
default for node groups appended from the asset libraries.

---

Note: This can be easily enabled for ID templates which can then be part
of T84669. It just need to call UI_but_icon_indicator_number_set in the
function template_add_button_search_menu.

Special thanks Clément Foucault for the help figuring out the shader,
Julian Eisel for the help navigating the UI code, and Pablo Vazquez for

c55d38f00b Geometry Nodes: viewport preview
This adds support for showing geometry passed to the Viewer in the 3d
viewport (instead of just in the spreadsheet). The "viewer geometry"
bypasses the group output. So it is not necessary to change the final
output of the node group to be able to see the intermediate geometry.

**Activation and deactivation of a viewer node**
* A viewer node is activated by clicking on it.
* Ctrl+shift+click on any node/socket connects it to the viewer and
  makes it active.
* Ctrl+shift+click in empty space deactivates the active viewer.
* When the active viewer is not visible anymore (e.g. another object
  is selected, or the current node group is exit), it is deactivated.
* Clicking on the icon in the header of the Viewer node toggles whether
  its active or not.

**Pinning**
* The spreadsheet still allows pinning the active viewer as before.
  When pinned, the spreadsheet still references the viewer node even
  when it becomes inactive.
* The viewport does not support pinning at the moment. It always shows
  the active viewer.

**Attribute**
* When a field is linked to the second input of the viewer node it is
  displayed as an overlay in the viewport.
* When possible the correct domain for the attribute is determined
  automatically. This does not work in all cases. It falls back to the
  face corner domain on meshes and the point domain on curves. When
  necessary, the domain can be picked manually.
* The spreadsheet now only shows the "Viewer" column for the domain
  that is selected in the Viewer node.
* Instance attributes are visualized as a constant color per instance.

**Viewport Options**
* The attribute overlay opacity can be controlled with the "Viewer Node"
  setting in the overlays popover.
* A viewport can be configured not to show intermediate viewer-geometry
  by disabling the "Viewer Node" option in the "View" menu.

**Implementation Details**
* The "spreadsheet context path" was generalized to a "viewer path" that
  is used in more places now.
* The viewer node itself determines the attribute domain, evaluates the
  field and stores the result in a `.viewer` attribute.
* A new "viewer attribute' overlay displays the data from the `.viewer`
  attribute.
* The ground truth for the active viewer node is stored in the workspace
  now. Node editors, spreadsheets and viewports retrieve the active
  viewer from there unless they are pinned.
* The depsgraph object iterator has a new "viewer path" setting. When set,
  the viewed geometry of the corresponding object is part of the iterator
  instead of the final evaluated geometry.
* To support the instance attribute overlay `DupliObject` was extended
  to contain the information necessary for drawing the overlay.
* The ctrl+shift+click operator has been refactored so that it can make
  existing links to viewers active again.
* The auto-domain-detection in the Viewer node works by checking the
  "preferred domain" for every field input. If there is not exactly one
  preferred domain, the fallback is used.

Known limitations:
* Loose edges of meshes don't have the attribute overlay. This could be
  added separately if necessary.
* Some attributes are hard to visualize as a color directly. For example,
  the values might have to be normalized or some should be drawn as arrays.
  For now, we encourage users to build node groups that generate appropriate
  viewer-geometry. We might include some of that functionality in future versions.
  Support for displaying attribute values as text in the viewport is planned as well.
* There seems to be an issue with the attribute overlay for pointclouds on
  nvidia gpus, to be investigated.

4130f1e674 Geometry Nodes: new evaluation system
This refactors the geometry nodes evaluation system. No changes for the
user are expected. At a high level the goals are:
* Support using geometry nodes outside of the geometry nodes modifier.
* Support using the evaluator infrastructure for other purposes like field evaluation.
* Support more nodes, especially when many of them are disabled behind switch nodes.
* Support doing preprocessing on node groups.

For more details see T98492.

There are fairly detailed comments in the code, but here is a high level overview
for how it works now:
* There is a new "lazy-function" system. It is similar in spirit to the multi-function
  system but with different goals. Instead of optimizing throughput for highly
  parallelizable work, this system is designed to compute only the data that is actually
  necessary. What data is necessary can be determined dynamically during evaluation.
  Many lazy-functions can be composed in a graph to form a new lazy-function, which can
  again be used in a graph etc.
* Each geometry node group is converted into a lazy-function graph prior to evaluation.
  To evaluate geometry nodes, one then just has to evaluate that graph. Node groups are
  no longer inlined into their parents.

Next steps for the evaluation system is to reduce the use of threads in some situations
to avoid overhead. Many small node groups don't benefit from multi-threading at all.
This is much easier to do now because not everything has to be inlined in one huge
node tree anymore.

223665b994 GPU: remove 'GPU_SHADER_2D_UNIFORM_COLOR'
The only real difference between `GPU_SHADER_2D_UNIFORM_COLOR` and
`GPU_SHADER_3D_UNIFORM_COLOR` is that in the vertex shader the 2D
version uses `vec4(pos, 0.0, 1.0)` and the 3D version uses
`vec4(pos, 1.0)`.

But VBOs with 2D attributes work perfectly in shaders that use 3D
attributes. Components not specified are filled with components from
`vec4(0.0, 0.0, 0.0, 1.0)`.

So there is no real benefit to having two different shader versions.

This will simplify porting shaders to python as it will not be
necessary to use a 3D and a 2D version of the shaders.

In python the new name for '2D_UNIFORM_COLOR'' and '3D_UNIFORM_COLOR'
is 'UNIFORM_COLOR', but the old names still work for backward
compatibility.

484a914647 UI: Add support for showing socket descriptions in tooltips
Currently, hovering over a socket itself shows no tooltip at all, while
hovering over its value field shows "Default value", which is not helpful.

This patch therefore implements socket tooltips following the proposal at
https://blender.community/c/rightclickselect/2Qgbbc/.

A lot of the basic functionality was already implemented for Geometry Nodes,
where hovering over the socket itself shows introspection info.

This patch extends this by:
- Supporting dynamic tooltips on labels, which is important for good tooltip
  coverage in a socket's region of the node.
- Adding a function to setting a dynamic tooltip for an entire uiLayout, which
  avoids needing to set it manually for a wide variety of socket types.
- Hiding the property label field in a tooltip when dynamic tooltip is also
  provided. If really needed, this label can be restored through the dynamic
  tooltip, but in all current cases the label is actually pointless anyways
  since the dynamic tooltip gives more accurate and specific information.
- Adding dynamic tooltips to a socket's UI layout row if it has a description
  configured, both in the Node Editor as well as in the Material Properties.

Note that the patch does not add any actual tooltip content yet, just the
infrastructure to show them. By default, sockets without a description still
show the old "Default value" tooltip.

For an example of how to add socket descriptions, check the Cylinder node
in the Geometry Nodes.

This commit moves declarations that depend on `FN_field.hh` out of

reduce the number of areas that need to depend on the functions module,
which recently came in in review of D11591.

In the future we may have a library of standard field inputs in order to
make composing algorithms easier, so it makes sense to have a header
that could contain them and some basic related utilities relating the
concepts of geometry and fields.

Reducing use of unnecessary headers may also reduce compilation time.

This commit removes the implementations of legacy nodes,

Now that we have two releases that included the legacy nodes,
there is not much reason to include them still. Removing the
code means refactoring will be easier, and old code doesn't
have to be tested and maintained.

After this commit, the legacy nodes will be undefined in the UI,
so 3.0 or 3.1 should be used to convert files to the fields system.

The net change is 12184 lines removed!

The tooltip for legacy nodes mentioned that we would remove
them before 4.0, which was purposefully a bit vague to allow
us this flexibility. In a poll in a devtalk post showed that the
majority of people were okay with removing the nodes.
