When closing the blender, while the callbacks are removed, the
reference count of the object used as `customdata` is not decremented.
This commit adds two functions that correctly release the
python `draw_callbacks` before releasing all `draw_callbacks`.

Missing code flow.

Current implementation was to restricting for future enhancements where
the CryptomatterLayer could be read from existing metadata.
|
|
|
|
This function will be used in another file with attribute search,
so it makes sense to share from the UI storage header.
|
|
This allows accessing attribute meta data like domain and data type
without having to create a `ReadAttribute`. I kept the `attribute_names`
method for now to keep the patch more self contained.

The Exact modifier code had been written to avoid using BMesh but
in the initial release the modifier still converted all Meshes to
BMeshes, and then after running the boolean code on the BMeshes,
converted the result back to a Mesh.
This change skips that. Most of the work here is in getting the
Custom Data layers right. The approach taken is to merge default
layers from all operand meshes into the final result, and then
use the original verts, edges, polys, and loops to copy or interpolate
the appropriate custom data layers from all operands into the result.

This patch adds a to_curve method to the Object ID. This method is
analogous to the to_mesh method. The method can operate on curve and
text objects. For text objects, the text is converted into a 3D Curve ID
and that curve is returned. For curve objects, if apply_modifiers is
true, the spline deform modifiers will be applied and a Curve ID with
the result will be returned, otherwise a copy of the curve will be
returned.
The goal of this addition is to allow the developer to access the splines
of text objects and to get the result of modifier applications which was
otherwise not possible.

This commit adds a simple string input node, intended for use in the
attribute workflow to make using the same attribute name in multiple
places easier. The node is function node similar to the existing vector
input node.

Following with the changes included to interpolate strokes of different number of points, a full review has been done in the interpolation tools.
* Interpolate now is a tool and not an operator. It was not logic to have this tool as a button.
* Interpolate tool parameters have been moved to topbar.
* Interpolate popover has been removed from topbar and interpolate `Sequence` operator has been moved to grease pencil menu.
* Interpolate Sequence now include a Redo panel.
* Interpolate tool now allows to select the strokes by pairs. This allows to interpolate any stroke with any stroke and not as before that it was only possible by drawing order. If no stroke is selected, the interpolation is done as before.
* Now is possible interpolate again if a previous keyframe exist. Before, it was impossible to interpolate two times in same frame and this made impossible to do the interpolation by groups of frames.
* New automatic option to `Flip strokes` if the stroke and end are not in the right position. Also the flip can be set manually for corner cases.
* Cleanup of menus related to interpolate.
* Fixed some bugs and removed parameters from scene because now all are tool or operator contained.
* Some code cleanup and function renames.
This commit also includes the some codebase to future implementation of the concept `Vertex Active` that now does not exist in grease pencil.

This patch implements the list panel system D7490 for FCurve modifiers.
The UI layouts are updated to make use of subpanels and to be consistent
with the rest of the interface, and easier to understand.
See the differential revision for screenshots.
This commit also significantly cleans up the FModifier UI code, and
improves, mainly by replacing the old button creation code is with
the newer interface API using RNA. In turn there is a bit of complexity
added because each FModifier has a separate panel.
Although reordering of FModifiers was not implemented before, we get
drag and drop basically for free here, so it is also included.
As noted in some older to do tasks, FModifiers aren't evaluated
in perfect order, which may be a point of improvement for the future.

Previously, functions would have to ask for every geometry type explicitely.
Using a vector is return type is fine. In practice this will probably never
allocate because of the small buffer optimization in vector.

|
|
This function will be used by multiple functions.

|
This makes it easier to use the api.

Avoid look for frame if the actual frame is already available.

"Kind" is a bit less generic than "Info" for me. Especially, it implies
that the struct does not contain the name of a specific attribute
(for me anyway).

This allows accessing per-point attributes on the corner domain,
which can be useful e.g. when adding per-point displacement
to per-corner uv coordinates.
Also it is required to make an upcoming patch work well, that
makes the Point Distribute node use density weights per corner
instead of per point, giving the user more precise control over
the distribution.
|
|
This makes vertex colors available in geometry nodes similar to
how uvs are available. They can be used using the attribute system.
Vertex colors are stored per corner (as are uvs, but not like vertex weights).

Previously, when a Geometry Nodes modifier outputs a point cloud
(e.g. generated using the Point Distribute node), other modifiers
could not use that data. Now, the point cloud data is converted to
mesh vertices for such modifiers.

The `material_index` attribute can adjust which material in the list
will be applied to each face of the mesh. There are two new things
about this attribute that haven't been exposed by the attribute API yet.
Each comes with limitations:
1. Integer data type: Most attribute nodes are currently written to use
float data types. This means that they can't write to this attribute
because they can't change the type of a built-in attribute.
2. Polygon domain: This is our first attribute using the polygon domain,
meaning until some of the interpolations are implemented, some
operations may not work as expected.
Currently the two nodes that work with this attribute are Attribute Fill
and Attribute Randomize.

mesh modifier
Previously, when the output of a Geometry Nodes modifier would
contain instances, those could not be accessed by other existing
modifiers (e.g. the Array modifier). That is because those modifiers
don't know about instances.
Upcoming commits will improve an this in two ways:
* Also realize instances before deform modifiers.
* Convert a point cloud in the geometry to mesh vertices so that
they can be accessed as well.
Note, making instances real can result in loosing some information
that we do not support in Geometry Nodes yet. That includes some
special builtin attributes like bevel weights.

Accidentally used 4 instead of `necs->length`.

Issue introduced by my commit: rB40b7929cc040
**User-level Problem**:
The issue resulted in a full-replace upper strip with only a Z location
channel full-replacing the XY location channels of the lower stack.
replaced to default. The expected behavior is that only the Z location
channel is affected.
**Technical-level Problem**:
Before the problematic commit, fcurves were blended as they were read.
So only existing animated channels would blend. My recent commit
changed the process to read all fcurve values into an isolated
upper_snapshot then blend with the lower stack. There is no data stored
to know whether the upper snapshot channel values were sampled from
fcurves or were default values. Only those sampled from fcurves should
be blended.
**Solution**:
Added a `blend_domain` bitmask member to NlaEvalChannelSnapshot.
The blending function only blends values within the `blend_domain`.
Sampled fcurve values are now marked as within the `blend_domain`.
We also now always copy the lower snapshot to the result snapshot which
only matters when they aren't the same. Currently, it's always the same
so the change is more for future unseen cases.

This patch adds icons to the right side of nodes when they encounter a
a problem. When hovered, a tooltip displays describing the encountered
while evaluating the node.
Some examples are: attribute doesn't exist, mesh has no faces,
incorrect attribute type, etc. Exposing more messages to the system
will be an ongoing process. Multiple warnings per node are supported.
The system is implemented somewhat generically so that the basic
structure can also be used to store more information from evaluation
for the interface, like a list of available attributes.
Currently the messages are just button tooltips. They could be styled
differently in the future. Another limitation is that every instance of
a node group in a parent node tree will have the same error messages,
the "evaluation context" used to decide when to display the tooltips
must be extended to support node tree paths.

lattice resolution from 1 to 3 or more.
Fix for T84928 .
Considering the changes , issue is resolved ( Ignoring readability issues) .
**Changes **:
- `Change in value assignment of fu/v/w :` Observing previous code , I noticed ,value assigned to them is equivalent to -0.5 ( i.e. co-ordinate of left most vertex of lattice size =1 where centre of lattice is origin ) .
- `Change in value assignment of du/v/w :` Margin ( distance ) between each division of surface along any axis is equivalent to **( (length of surface along axis ) / (no of division line - 1) )** . that's why is changed it to (default_size/unew -1) .
- ` New variable declared "default_size" :` As far as I gone through the code , I noticed values 1 < du ,fu < 1 , which indicates these values were calculated with respect to default lattice of size 1 .
- `removed pntsu/v/w != 1 check :` Following changes inside the if block worked properly for pntsu/v/w = 1 .
