Currently only affects 'UI' IDs (WindowManager, Screen, etc.), but in
the future other types may be affected as well.
NOTE: this is only used in readfile code itself, not in the
post-processing performed by `setup_app_data`, as this code is too
specific for such generic handling.
Current implementation had some faulty assumtions and had some work
arounds for crashes that were actually limitation of the implementation.
The main reason for this was that the implementation didn't add new
primitives in the same direction it was already adding. Some when
incorrect behavior was detected it was assumed that the part wasn't
manifold (anymore) and didn't fix that part of the mesh.
The new implementation will extract a solution and use this solution
also as the order to generate primitives in uv space.
This patch fixes several crashes and improves the overall quality
when fixing seam bleeding. It also adds additional debug tools
(print_debug) implementation in order to find issues faster in the
future.
Only one point should be used to create a reference rotation for other
points to follow. Using two caused the resulting twist to be
asymmetric, especially noticeable on symmetrical, cyclic curves.
Alternate fix to D11886 which caused T101843.
Make the functions more flexible and more generic by changing the curves
arguments to the curve offsets. This way, theoretically they could become
normal utility functions in the future. Also do a consistency pass over
the algorithms that generate new curves geometry for naming and
code ordering, and use of utility functions. The functions are really
quite similar, and it's much easier to tell this way.
`PBVH_Leaf` nodes are now split into a new `PBVH_TexLeaf`
node type when using the paint brush. These nodes are
split by image pixels, not triangles. This greatly
increases performance when working with large
textures on low-poly meshes.

Rewrite of the Workbench engine using C++ and the new Draw Manager API.
The new engine can be enabled in Blender `Preferences > Experimental > Workbench Next`.
After that, the engine can be selected in `Properties > Scene > Render Engine`.
When `Workbench Next` is the active engine, it also handles the `Solid` viewport mode rendering.
The rewrite aims to be functionally equivalent to the current Workbench engine, but it also includes some small fixes/tweaks:
- `In Front` rendered objects now work correctly with DoF and Shadows.
- The `Sampling > Viewport` setting is actually used when the viewport is in `Render Mode`.
- In `Texture` mode, textured materials also use the material properties. (Previously, only non textured materials would)
To do:
- Sculpt PBVH.
- Volume rendering.
- Hair rendering.
- Use the "no_geom" shader versions for shadow rendering.
- Decide the final API for custom visibility culling (Needed for shadows).
- Profile/optimize.
Known Issues:
- Matcaps are not loaded until they’re shown elsewhere. (e.g. when opening the `Viewort Shading` UI)
- Outlines are drawn between different materials of the same object. (Each material submesh has its own object handle)

This uses the changes from ef68a37e5d to create IDProperties
for exposed boolean sockets with a boolean type instead of an integer
with a [0,1] range. Existing properties and values are converted
automatically.
For forward compatibility, the properties are switched to the integer
type for saving. Otherwise older versions crash immediately when opening
a newer file. The "Use Attribute" IDProperties aren't changed here,
since that wouldn't have a visible benefit.

Caused by 05952aa94d, which removed the use of the
active tessface UV pointer on meshes but didn't replace it properly with
the equivalend custom data API function.
This adds a new `Interpolate Curves` node. It allows generating new curves
between a set of existing guide curves. This is essential for procedural hair.
Usage:
- One has to provide a set of guide curves and a set of root positions for
the generated curves. New curves are created starting from these root
positions. The N closest guide curves are used for the interpolation.
- An additional up vector can be provided for every guide curve and
root position. This is typically a surface normal or nothing. This allows
generating child curves that are properly oriented based on the
surface orientation.
- Sometimes a point should only be interpolated using a subset of the
guides. This can be achieved using the `Guide Group ID` and
`Point Group ID` inputs. The curve generated at a specific point will
only take the guides with the same id into account. This allows e.g.
for hair parting.
- The `Max Neighbors` input limits how many guide curves are taken
into account for every interpolated curve.

During 3D texturing the uv islands are extended in order to fix seam bleeding
for manifold parts of the input mesh. This patch adds a `print_debug` method
on UVIsland that generates a python script. This script can be copy-past
into the Python Console to show the generated geometry.
This script can be extended to show the extracted border and use face colors
for showing internal decisions.
Mesh islands (shells) are now calculated on an as-needed
basis and cached inside of a temp attribute,
`sculpt_topology_island_key`. This attribute is updated
as needed when geometry changes (e.g. the trim brush)
or when mesh visibility changes.
This replaces the old behavior where the "topology" automasking
mode would walk the entire mesh on every stroke.
Based on discussion about T102962, rename the "Face Set Boundaries" node
to "Face Group Boundaries" and the Accumulate Field node's "Group Index"
socket to "Group ID". This convention of "__ Group" and "Group ID" will
be used more in other nodes in the future.
This commit doesn't affect forwards or backwards compatibility.
While we do need higher level utilities for copying attributes
between geometries, this currently isn't used and it's not clear
that it will be the right abstraction in the end.
When all the curves are poly curves, skip the work of building a
separate array of offsets for the evaluated points (which are the
same as the control points). This saves 1-4ms on every reevaluation
in test files with many curves.
Standardizing the process of creating a new CurvesGeometry with
different curve sizes based on an existing curves is helpful, since
there are a few methods to simplify the process that aren't obvious
at first, like filling the offsets with sizes directly and accumulating
them to become sizes.
Also, in the trim curves node, avoid creating the curve types attribute
all the time. Use the special API functions for the types which do
some optimizations automatically. Also use a more consistent
method to copy the curve domain data, and correct some comments.
The same logic from D17025 is used in other places in the curve code.
This patch uses the class for the evaluated point offsets and the Bezier
control point offsets. This helps to standardize the behavior and make
it easier to read.
Previously the Bezier control point offsets used a slightly different standard
where the first point was the first offset, just so they could have the same
size as the number of points. However two nodes used a helper function
to use the same `OffsetIndices` system, so switch to that there too.
That requires removing the subtraction by one to find the actual offset.
Also add const when accessing data arrays from curves, for consistency.

Previously, transforming a clip (scaling, repeat, etc) wouldn't re-calculate the blend-in and blend-out values, leading to over / undershoot, and a visual clip artifact
Old:
{F14045003}
This patch adds re-calculation logic (new `BKE_nlastrip_recalculate_blend()` method) to the blend-in/out on transformations to clamp values, and avoid over/under shoot.
The `BKE_nlastrip_recalculate_blend()` encapsulates the existing logic for both the `rna_NlaStrip_blend_in_set()` and `rna_NlaStrip_blend_out_set()` methods into a single BKE method that we an execute as needed. The fact that blend-in is first decreased, is strictly on the order of calculation. My suspicion is that //if// the blend-in / blend-our values were working as intended, the RNA set methods would update in order, and we'd experience the same thing. In short, the choice here was to linearly combine the logic, without making any assumptions of my own.
while talking things over with @sybren and @RiggingDojo, they are fine with how this currently works, but there a desire to update how the two values interact with each (ratio scale, etc) in the future.

This was the case when using the operator outside of the modifiers panel.
Caused by {rBeae36be372a6}.
In above commit, `DT_layer_items` shared both `DT_TYPE_MPROPCOL_LOOP` |
`DT_TYPE_MLOOPCOL_LOOP` in a single EnumPropertyItem value "Colors".
This is a bit unusual, but probably allowed.
As a consequence, checks for specific datatypes would fail when selecting
such EnumPropertyItem:
- `DT_DATATYPE_IS_MULTILAYERS` (uses `ELEM` to check distinct entries --
would return false)
- `BKE_object_data_transfer_dttype_to_srcdst_index` (would return
`DT_MULTILAYER_INDEX_INVALID`)
These places have now been corrected to take these "special" values into
account.
Another issue was that multiple EnumPropertyItems with the same value
could be created in dt_add_vcol_layers() if attributes of the same
domain, but different color types are in play (could lead to crashes)
and that has also been corrected.
Also: above commit did not give the choice of transfering color
attributes from the vertex domain (only face corner attributes could be
chosen), this has now been added. DT_layer_vert_items (used from the
modifier) already had this included so this was only an issue when using
the operator outside of the modifiers panel.
Since we now feature two domains, the single "VCOL" in the enum has been
split into "COLOR_VERTEX" and "COLOR_CORNER". This will break existing
scripts calling bpy.ops.object.datalayout_transfer and will be marked as
a breaking change in the release notes.
NOTE: there is another bug here when attributes of the same domain, but
different color types are in play and you want to transfer just a single
specific layer (but that is for a separate commit)

Goal of this patch is to stop the invocation of OpenGL calls via the bgl module
on a none OpenGL GPU backend, report this as a python deprecation warning
and report this to the user.
## Deprecation warning to developers
```
>>> import bgl
>>> bgl.glUseProgram(0)
<blender_console>:1: DeprecationWarning: 'bgl.glUseProgram' is deprecated and will be removed in Blender 3.7. Report or update your script to use 'gpu' module.
```
## Deprecation message to users
The message to the user is shown as part of the Info Space and as a message box.
{F14159203 width=100%}
{F14158674 width=100%}
During implementation we tried several ideas:
# Use python warning as errors: This isn't fine grained enough and can show incorrect information to the user.
# Throw deprecation as error and use sys.excepthook to report the user message.
This required a custom exception class to identify the bgl deprecation and a CPython handler function to
be set during python initialization. Although this is the most flexible there was a disconnect between the
exception class, exception function and the excepthook registration.
# A variant how we handle autoexec failures. A flag is stored in Global and when set the user message is reported.
Not that flexible, but code is more connected to the boolean stored in the Global struct.
Although using Global struct isn't nice I chose this solution due to its traceability. It is clear to developers
reading the code how the mechanism works by using search all functionality of your IDE.

note that this may be left unset if it's not needed.
- Remove BOOST/OPENVDB/VULKAN references when disable.
- Define INC_SYS even when empty.
