The value of this flag was never used.

Remove functions and function pointers that were never set or never
used at all. The "tessface" original index handling in `subsurf_ccg.c`
can be removed because the data was never used.

This function and flags weren't used outside of DerivedMesh
code, and since the plan is to remove the data structure, it makes
sense to remove complexity where possible.
|

This is similar to e032ca2e25bf2e305b66 which removed the
callback for volumes. Now that we have geometry sets, there is
no need to define a callback for every data type, and this wasn't
used. Procedural curves/hair editing will use nodes rather than new
modifier types anyway.

Previously, macros were ifdefed using the cmake option `WITH_INTERNATIONAL`
However, the is unnecessary as withen the functions themselves have checks for building without internationalization.
This also means that many `add_definitions(-DWITH_INTERNATIONAL)` are also unnecessary.

As part of the project of converting `MVert` into `float3`
(more details in T93602), this is an easy step, since it
is only locally used runtime data. In the six places it was
used, the flag was replaced by a local bitmap.
By itself this change has no benefits other than making some
code slightly simpler. It only really matters when the other
flags are removed and it can be removed from `MVert`
along with the bevel weight.

Adding better support for drawing huge images in the image/uv editor. Also solved tearing artifacts.
The approach is that for each image/uv editor a screen space gpu texture is created that only contains
the visible pixels. When zooming or panning the gpu texture is rebuild.
Although the solution isn't memory intensive other parts of blender memory usage scales together with
the image size.
* Due to complexity we didn't implement partial updates when drawing images tiled (wrap repeat).
This could be added, but is complicated as a change in the source could mean many different
changes on the GPU texture. The work around for now is to tag all gpu textures to be dirty when
changes are detected.
Original plan was to have 4 screen space images to support panning without gpu texture creation.
For now we don't see the need to implement it as the solution is already fast. Especially when
GPU memory is shared with CPU ram.

This patch reimplements the image partial updates. Biggest design motivation for the redesign
is that currently GPUTextures must be owned by the image. This reduces flexibility and adds
complexity to a single component especially when we want to have different structures.
The new design is not limited to GPUTextures and can also be used by reducing overhead in image
operations like scaling. Or partial image updating in Cycles.
The usecase in hand is that we want to support virtual images in the image editor so we can
work with images that don't fit in a single GPUTexture.
Using `BKE_image_partial_update_mark_region` or `BKE_image_partial_update_mark_full_update`
a part of an image can be marked as dirty. These regions are stored per ImageTile (UDIM).
When a part of the code wants to receive partial changes it needs to construct a `PartialUpdateUser`
by calling `BKE_image_partial_update_create`. As long as this instance is kept alive the changes can
be received.
When a user wants to update its own data it will call `BKE_image_partial_update_collect_changes`
This will collect the changes since the last time the user called this function. When the partial changes
are available the partial change can be read by calling `BKE_image_partial_update_get_next_change`
It can happen that the introduced mechanism doesn't have the data anymore to construct the
changes since the last time a PartialUpdateUser requested it. In this case it will get a request
to perform a full update.

Though the edge vertices aren't really meant to have an order,
it can make a difference in operations when there isn't any other
information to make decisions from, like etruding a circle of
loose edges (the situation in the report). This commit changes
the order of the vertices in the final cyclic edge to go in the
same direction as all of the other edges.

The vertex and face normals from the input mesh
were used to calculate the normals on the result,
which could cause a crash because the result should
be about twice as large.
Also remove an unnecessary dirty tag, since it is handled
automatically when creating a new mesh or in the case
of the mirror modifier, when calculating the new custom
face corner normals.

Add `USD Preview Surface From Nodes` export option, to convert a
Principled BSDF material node network to an approximate USD Preview
Surface shader representation. If this option is disabled, the original
material export behavior is maintained, where viewport setting are saved
to the Preview Surface shader.
Also added the following options for texture export.
- `Export Textures`: If converting Preview Surface, export textures
referenced by shader nodes to a 'textures' directory which is a
sibling of the USD file.
- `Overwrite Textures`: Allow overwriting existing texture files when
exporting textures (this option is off by default).
- `Relative Texture Paths`: Make texture asset paths relative to the
USD.
The entry point for the new functionality is
`create_usd_preview_surface_material()`, called from
`USDAbstractWriter::ensure_usd_material()`. The material conversion
currently handles a small subset of Blender shading nodes,
`BSDF_DIFFUSE`, `BSDF_PRINCIPLED`, `TEX_IMAGE` and `UVMAP`.
Texture export is handled by copying texture files from their original
location to a `textures` folder in the same directory as the USD.
In-memory and packed textures are saved directly to the textures folder.
This patch is based, in part, on code in Tangent Animation's USD
exporter branch.

During sprite fright loading of complex scenes would spend a long time in remapping ID's
The remapping process is done on a per ID instance that resulted in a very time consuming
process that goes over every possible ID reference to find out if it needs to be updated.
If there are N of references to ID blocks and there are M ID blocks that needed to be remapped
it would take N*M checks. These checks are scattered around the place and memory.
Each reference would only be updated at most once, but most of the time no update is needed at all.
Idea: By grouping the changes together will reduce the number of checks resulting in improved performance.
This would only require N checks. Additional benefits is improved data locality as data is only loaded once
in the L2 cache.
It has be implemented for the resyncing process and UI editors.
On an Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz 16Gig the resyncing process went
from 170 seconds to 145 seconds (during hotspot recording).
After this patch has been applied we could add similar approach
to references (references between data blocks) and functionality (tagged deletion).
In my understanding this could reduce the resyncing process to less than a second.

This implements a merge by distance operation for point clouds.
Besides the geometry input, there are two others-- a selection
input to limit the operation to certain points, and the merge
distance. While it would be a reasonable feature, the distance
does not support a field currently, since that would make
the algorithm significantly more complex.
All attributes are merged to the merged points, with the values
mixed together. This same generic method is used for all attributes,
including `position`. The `id` attribute uses the value from the
first merged index for each point.
For the implementation, most of the effort goes into creating a
merge map to speed up attribute mixing. Some parts are inherently
single-threaded, like finding the final indices accounting for the
merged points. By far most of the time is spend balancing the
KD tree.
Mesh support will be added in the next commit.

Allows to perform correction of coordinate delta/displacement in a
similar way of how sculpt mode handles sculpting on a deformed mesh.
An example of usecase of this is allowing riggers and sciprters to
improve corrective shapekey workflow.
The usage consists of pre-processing and access. For example:
object.crazyspace_eval(depsgraph, scene)
# When we have a difference between two vertices and want to convert
# it to a space to be stored, say, in shapekey:
delta_in_orig_space = rigged_ob.crazyspace_displacement_to_original(
vertex_index=i, displacement=delta)
# The reverse of above.
delta_in_deformed_space = rigged_ob.crazyspace_displacement_to_deformed(
vertex_index=i, displacement=delta)
object.crazyspace_eval_clear()

The evaluated mesh is a result of evaluated modifiers, and referencing
other evaluated IDs such as materials.
It can not be stored in the EditMesh structure which is intended to be
re-used by many areas. Such sharing was causing ownership errors causing
bugs like
T93855: Cycles crash with edit mode and simultaneous viewport and final render
The proposed solution is to store the evaluated edit mesh and its cage in
the object's runtime field. The motivation goes as following:
- It allows to avoid ownership problems like the ones in the linked report.
- Object level is chosen over mesh level is because the evaluated mesh
is affected by modifiers, which are on the object level.
This patch allows to have modifier stack of an object which shares mesh with
an object which is in edit mode to be properly taken into account (before
the change the modifier stack from the active object will be used for all
objects which share the mesh).
There is a change in the way how copy-on-write is handled in the edit mode to
allow proper state update when changing active scene (or having two windows
with different scenes). Previously, the copt-on-write would have been ignored
by skipping tagging CoW component. Now it is ignored from within the CoW
operation callback. This allows to update edit pointers for objects which are
not from the current depsgraph and where the edit_mesh was never assigned in
the case when the depsgraph was evaluated prior the active depsgraph.
There is no user level changes changes expected with the CoW handling changes:
should not affect on neither performance, nor memory consumption.
Tested scenarios:
- Various modifiers configurations of objects sharing mesh and be part of the
same scene.
- Steps from the reports: T93855, T82952, T77359
This also fixes T76609, T72733 and perhaps other reports.

This patch introduces an extrude node with three modes. The vertex mode
is quite simple, and just attaches new edges to the selected vertices.
The edge mode attaches new faces to the selected edges. The faces mode
extrudes patches of selected faces, or each selected face individually,
depending on the "Individual" boolean input.
The default value of the "Offset" input is the mesh's normals, which
can be scaled with the "Offset Scale" input.
**Attribute Propagation**
Attributes are transferred to the new elements with specific rules.
Attributes will never change domains for interpolations. Generally
boolean attributes are propagated with "or", meaning any connected
"true" value that is mixed in for other types will cause the new value
to be "true" as well. The `"id"` attribute does not have any special
handling currently.
Vertex Mode
- Vertex: Copied values of selected vertices.
- Edge: Averaged values of selected edges. For booleans, edges are
selected if any connected edges are selected.
Edge Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected extruded
edges. For booleans, the edges are selected if any connected
extruded edges are selected.
- Duplicate edges: Copied values of selected edges.
- Face: Averaged values of all faces connected to the selected edge.
For booleans, faces are selected if any connected original faces
are selected.
- Corner: Averaged values of corresponding corners in all faces
connected to selected edges. For booleans, corners are selected
if one of those corners are selected.
Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected selected
edges, not including the edges "on top" of extruded regions.
For booleans, edges are selected when any connected extruded edges
were selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
Individual Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of the two neighboring
edges on each extruded face. For booleans, edges are selected
when at least one neighbor on the extruded face was selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
**Differences from edit mode**
In face mode (non-individual), the behavior can be different than the
extrude tools in edit mode-- this node doesn't handle keeping the back-
faces around in the cases that the edit mode tools do. The planned
"Solidify" node will handle that use case instead. Keeping this node
simpler and faster is preferable at this point, especially because that
sort of "smart" behavior is not that predictable and makes less sense
in a procedural context.
In the future, an "Even Offset" option could be added to this node
hopefully fairly simply. For now it is left out in order to keep
the patch simpler.
**Implementation**
For the implementation, the `Mesh` data structure is used directly
rather than converting to `BMesh` and back like D12224. This optimizes
for large extrusion operations rather than many sequential extrusions.
While this is potentially more verbose, it has some important benefits:
First, there is no conversion to and from `BMesh`. The code only has
to fill arrays and it can do that all at once, making each component of
the algorithm much easier to optimize. It also makes the attribute
interpolation more explicit, and likely faster. Only limited topology
maps must be created in most cases.
While there are some necessary loops and allocations with the size of
the entire mesh, I tried to keep everything I could on the order of the
size of the selection rather than the size of the mesh. In that respect,
the individual faces mode is the best, since there is no topology
information necessary, and the amount of work just depends on the size
of the selection.
Modifying an existing mesh instead of generating a new one was a bit
of a toss-up, but has a few potential benefits:
- Avoids manually copying over attribute data for original elements.
- Avoids some overhead of creating a new mesh.
- Can potentially take advantage of future ammortized mesh growth.
This could be changed easily if it turns out to be the wrong choice.

This commit improves NURBS knot generation by adding proper support
for the combination of the Bezier and cyclic options. In other cases
the resulting knot doesn't change. This cyclic Bezier knot is used to
create accurate accurate "Nurbs Circle", "Nurbs Cylinder" primitives.
"Nurbs Sphere" and "Nurbs Torus" primitives are also improved by
tweaking the spin operator.
The knot vector in 3rd order NURBS curve with Bezier option turned on
(without cyclic) is changed in comparison to previous calculations,
although it doesn't change the curve shape itself.
The accuracy of the of NURBS circle is fixed, which can be checked by
comparing with mesh circle. Tessellation spacing differences in
circular NURBS is also fixed, which is observable with the NURBS
cylinder and sphere primitives. These were causing seam-like effects.

Currently there is no way to flip normals in geometry nodes. This node
makes that possible by flipping the winding order of selected faces.
The node is purposely not called "Flip Normals", because normals are
derived data, changing them is only a side effect. The real change is
that the vertex and edge indices in the face corners of every selected
polygon are reversed, and face corner attribute data is reversed.
While there are existing utilities to flip a polygon and its custom
data, this node aims to process an attribute's data together instead
of processing all attributes separately for each index.
