The function applying the search used the dummy search info for when
the item doesn't exist even when there was no UI data associated with
the node at all.
A fix is to only add the search menu when there is attribute info
stored for the node. This is something I wanted to do anyway, since
it makes it look more purposeful when there are no attribute info
for a node, less like a bug.

This introduces a context path to the spreadsheet editor, which contains
information about what data is shown in the spreadsheet. The context
path (breadcrumbs) can reference a specific node in a node group
hierarchy. During object evaluation, the geometry nodes modifier checks
what data is currently requested by visible spreadsheets and stores
the corresponding geometry sets separately for later access.
The context path can be updated by the user explicitely, by clicking
on the new icon in the header of nodes. Under some circumstances,
the context path is updated automatically based on Blender's context.
This patch also consolidates the "Node" and "Final" object evaluation
mode to just "Evaluated". Based on the current context path, either
the final geometry set of an object will be displayed, or the data at
a specific node.
The new preview icon in geometry nodes now behaves more like
a toggle. It can be clicked again to clear the context path in an
open spreadsheet editor.
Previously, only an object could be pinned in the spreadsheet editor.
Now it is possible to pin the entire context path. That allows two
different spreadsheets to display geometry data from two different
nodes.
The breadcrumbs in the spreadsheet header can be collapsed by
clicking on the arrow icons. It's not ideal but works well for now.
This might be changed again, if we get a data set region on the left.

This patch adds domain and data type information to each row of the
attribute search menu. The data type is displayed on the right, just
like how the list is exposed for the existing point cloud and hair
attribute panels. The domain is exposed on the left like the menu
hierarchy from menu search.
For the implementation, the attribute hint information is stored as a
set instead of a multi-value map so that every item (which we need to
point to descretely in the search process) contains the necessary data
type and domain information by itself. We also need to allocate a new
struct for every button, which requires a change to allow passing a
newly allocated argument to search buttons.
Note that the search does't yet handle the case where there are two
attributes with the same name but different domains or data types in
the input geometry set. That will be handled as a separate improvement.

This is especially useful when trying to add a node group instance, e.g. via
drag & drop from the Outliner or Asset Browser.
Previously this would just silently fail, with no information why. This is a
source of confusion, e.g. earlier, it took me a moment to realize I was
dragging a node group into itself, which failed of course.
Blender should always try to help the user with useful error messages.
Adds error messages like: "Nesting a node group inside of itself is not
allowed", "Not a compositor node tree", etc.
Adds a disabled hint return argument to node and node tree polling functions.
On error the hint is reported, or could even be shown in advance (e.g. if
checked via an operator poll option).

Previously, the spreadsheet editor could only show data of the original
and of the final evaluated object. Now it is possible to show the data
at some intermediate stages too.
For that the mode has to be set to "Node" in the spreadsheet editor.
Furthermore, the preview of a specific node has to be activated by
clicking the new icon in the header of geometry nodes.
The exact ui of this feature might be refined in upcoming commits.
It is already very useful for debugging node groups in it's current
state though.

Previously, `node_name` was rarely actually a name of a node. It is set
correctly as node name in `ED_node_tree_push`. However, later on it
was overwritten by the name of an id data block in `node_draw_space`.
Now, the node_name stays the name of the "parent" node. Whereas
display_name is the name that will be displayed in the breadcrumbs.
With this change, the `node_name` can be used to reconstruct the
actual path from the root node tree to the currently visible tree.

This is an implementation of Enhanced Subpixel Morphological Antialiasing (SMAA)
The algorithm was proposed by:
Jorge Jimenez, Jose I. Echevarria, Tiago Sousa, Diego Gutierrez
This node provides only SMAA 1x mode, so the operation will be done with no spatial
multisampling nor temporal supersampling. See Patch for comparisons.
The existing AA operation seems to be used only for binary images by some other nodes.
Using SMAA for binary images needs no important parameter such as "threshold", so we
perhaps can switch the operation to SMAA, though that changes existing behavior.
Notes:
1. The program code assumes the screen coordinates are DirectX style that the
vertical direction is upside-down, so "top" and "bottom" actually represent bottom
and top, respectively.

This makes the buttons drawn on nodes for unconnected string and color
sockets draw with the correct 40% ratio for the label split rather than
the old 50% ratio not used elsewhere in Blender anymore. The benefit is
a cleaner look, because the button edges line up better with others, and
a bit more space to type in attribute names.
Added a condition to the poll so that it ignores drag and drop on the button. The Paste Name operator is just not implemented. Doesn't work for shading nodes either.

This patch adds the ability to mute individual wires in the node editor.
This is invoked like the cut links operator but with a new shortcut.
Mute = Ctrl + Alt
Cut = Ctrl
Dragging over wires will toggle the mute state for that wire.
The muted wires are drawn in red with a bar across the center.
Red is used in the nodes context to indicate invalid links, muted links and internal links.
When a wire is muted it exposes the original node buttons which are normally hidden when a wire is connected.
Downstream and upstream links connected using reroute nodes are also muted.
Outside scope of patch:
- Add support for pynodes e.g. Animation Nodes
- Requires minor change to check for muted links using the `is_muted` link property or the `is_linked` socket property.

In the current implementation, cryptomatte passes are connected to the node
and elements are picked by using the eyedropper tool on a special pick channel.
This design has two disadvantages - both connecting all passes individually
and always having to switch to the picker channel are tedious.
With the new design, the user selects the RenderLayer or Image from which the
Cryptomatte layers are directly loaded (the type of pass is determined by an
enum). This allows the node to automatically detect all relevant passes.
Then, when using the eyedropper tool, the operator looks up the selected
coordinates from the picked Image, Node backdrop or Clip and reads the picked
object directly from the Renderlayer/Image, therefore allowing to pick in any
context (e.g. by clicking on the Combined pass in the Image Viewer). The
sampled color is looked up in the metadata and the actual name is stored
in the cryptomatte node. This also allows to remove a hash by just removing
the name from the matte id.
Technically there is some loss of flexibility because the Cryptomatte pass
inputs can no longer be connected to other nodes, but since any compositing
done on them is likely to break the Cryptomatte system anyways, this isn't
really a concern in practise.
In the future, this would also allow to automatically translate values to names
by looking up the value in the associated metadata of the input, or to get a
better visualization of overlapping areas in the Pick output since we could
blend colors now that the output doesn't have to contain the exact value.

Because the search didn't run when the menu first opens, the attributes
appeared in a different order than after you typed anything into the
search field. This commit instead runs the search when the menu
is first opened, but it only sorts items without filtering.
Pasting nodes can create new id relations, because nodes can reference IDs.
Therefore the depsgraph has to be updated when nodes are pasted.
We could somehow check if the pasted nodes referenced IDs, but I'm not sure
if this complexity is worth it.
Because pressing enter will choose the current search item from the menu,
and there was no search item with an empty string, it was impossible to
clear the text of an attribute text field. This commit adds a simple "X"
icon in the top row when you delete the string.
This commit exposes the strings used in the node error messages for
localization. It also changes the message tooltip creation to
automatically add the period at the end, to be more consistent with
the (arguably bad) design of other tooltips in Blender.
Calling `TIP_` directly in the node implementation files allows us to
continue using `std::string` concatenation instead of passing variadic
arguments. It's also more explicit about which part of the message is
translated and which isn't. The files already include the translation
header anyway.
The `bNodeLinkDrag` struct was NULL when dragging a node instead of
a link. It is allocated with `calloc` anyway, so this field doesn't
need to be explitely cleared.
The socket drag operator stored the index of the last picked socket
into RNA in case the mouse cursor leaves the link while dragging.
This id was not unique which is why sometimes a link from an other node
with the same id is picked.
This patch changes the way the last picked link is stored and stores a
pointer to the link directly into bNodeLinkDrag struct instead.

This commit adds a search for existing attributes when you click
on an attribute field. This is useful because otherwise you have
to remember which attributes should be available at each node in
the tree.
The fundamental complication is that this information is not
accessible statically. So the search data is only a cache from
the previous node tree evaluation. The information is added
with `BKE_nodetree_attribute_hint_add`, currently for every
input geometry socket for a single node.
This is only an initial implementation, and later versions will
expose the data type and domain of the attributes.
Differential Revision: https://developer.blender.org/D10519
Currently when you open an RNA collection search button, like a
vertex group selector, the search filter isn't applied until you
start typing, in order to display every option at the start.
Otherwise they wouldn't be visible, since the search filter would
run for the current text.
Currently this check happens in one place, but it relies on the
`changed` value of `uiBut`. This is fine in the interface directory,
but anywhere else it would require exposing `uiBut.changed`, which
is probably too low-level to expose.
The solution is adding an `is_first` argument to the search callbacks,
which is nice for a few reasons:
- They work at a higher level of abstraction, meaning they don't
have to worry about how exactly to tell if this is the first
search.
- It makes it easier to do special behavior when the search menu
is first opened.
- Then, obviously, it makes that state accessible without including
`interface_intern.h`.
