Previously the only way to control the subtype was to remove the group
input or output and create it again. This commit adds a dropdown to
change an existing socket, for supported socket types.

It was necessary to fix the UI code slightly; the layout's context
wasn't being used in calls to an operator's enum items callback.

The potential optimization in the normal edit modifier when flipping
faces isn't worth the "API impurity" and complexity introduced by
adding poly normal editing as part of the API. This change simplifies
future changes to the ownership of poly normals with a shared cache,
which can prevent recomputing poly normals completely.
Vertex positions and faces aren't changed, so most caches shouldn't
need to be tagged. This removes unnecessary re-computation of bounds,
triangulation, loose edges, etc.

Make it a native Cycles light option instead of counter-acting the inverse
area calculation in Hydra.

HdRenderDelegate got a change with the interface, adding gpuSupported. It
currently is just a dummy implementation without checking for anything
GPU-related.

The problem is that `set_geometry()` otherwise ends up implicitly
casting `Geometry*` to bool. In Blender this worked because the
geometry header was always included before the object header.

Allows NLA strips to horizontally translated over each other. If a strip is dropped when translating, it'll cause the strip to shuffle into place.

Abstracted large conditional branch in `recalcData_nla` into it's own `nlastrip_fix_overlapping` method for increased readability. No logical changes were made.

Use raw Blender structs and mesh data rather than using the RNA API.
There isn't any benefit from using the RNA when Cycles is compiled
with Blender anyway, and a profile showed that the majority of time
was spent in Blender RNA API functions.
This gives a significant improvement in performance when ingesting
meshes. Here are some tests of the runtime of the `create_mesh`
function (in seconds):
| | Before | After |
| ------------------------- | ------ | ----- |
| Grid | 0.66 | 0.11 |
| Many realized cubes | 2.60 | 0.48 |
| Large curve to mesh setup | 4.18 | 1.14 |
Also change to resizing the arrays and filling them by index rather
than appending. This makes the parallel aspect of the logic clearer,
and makes the loops easier to parallelize in the future, and makes
it easier to have a performance benefit when an attribute like
`sharp_face` doesn't exist.

Use the dot product of the normal of the two polygons connected to the
edge to calculate the edge factor.
This fixes#90641 and #102545 and ensures more predictable results for
boundary and non-manifold edges.

No functional changes.
Edges hidden by Optimal Display are hidden by edge factor Shader.
But there is not much advantage in doing this, as the number of edges
hidden by the Optimal Display is usually much higher than the number of
visible edges.
And the lines extractor does not include invisible edges due to other
factors.
So this change makes:
- Visibility test more consistent with what is actually seen.
- Smaller buffer for IBO sent to GPU
- consistency with GPU Subdivision that already considers Optimal Display
- Allows possible improvement in the "Edge Factor" extraction by making
it unnecessary to check the Optimal Display (except for optimization).

Popover menu buttons had their labels translated but not their
descriptions, although they were properly extracted.
This commit fixes that using the `TIP_()` macro.
This information is displayed in the top left of the 3D Viewport with
other text info. The units of the grid are already extracted, but they
were not translated in the drawing code.
Remove comments from `eBConstraint_Types` that
- were used long ago during a big refactor effort, but are no longer
necessary, or
- just repeated the name of the enum constant.
No functional changes.
OpenEXR has some dependecies that other other modules in Blender
requires. When disabling OpenEXR these dependecies could not match
and building blender would fail.
This PR disables the next options when `WITH_IMAGE_OPENEXR=Off`
- `WITH_OPENVDB`
- `WITH_ALEMBIC`
- `WITH_VULKAN_BACKEND`
- `WITH_CYCLES_OSL`
Additionally windows stores the IMath libraries in `IMATH_LIBRARIES`
Linux and Mac stored the IMath libraries in `IMATH_LIBRARY`. This
change will also adds `IMATH_LIBRARIES` variable to all platforms.

Splitting workload dependency chains such that they
only exist within the context of a single frame.
Dependencies are required to ensure sequential
command buffer submissions execute in order,
but the additional dependencies between frames
could incur GPU timeouts, if a signal was delayed.
This could be triggered by both CPU/GPU cycles
texture updates and Viewport Compositor operations.
Should also resolve#106401

Reduce register spill to global memory in raytrace_resolve
function. Results in a 20% uplift for this particular shader on
Apple Silicon GPUs. Contributing to 3-5% uplift for scenes
which have SSR enabled. This is achieved via reducing
memory pressure using a packed data type for the sampling
kernel.

Very sadge to see this kind of mistakes still exist in 2023 code...
While in theory this commit could be backported to (LTS) releases, would
rather only do it if/when proven it actually fixes user-facing issues.
Fixing such issues so deep in ID management code can have completely
unexpected side effects.
The framebuffer default size was only set during the first bind. This
is because the `dirty_attachments_ tag` wasn't set and thus the
framebuffer size was never passed down to the GL.
Split to `default_size_set()` to not affect other code paths that use
`size_set()`.
Adds the ability to pack UVs back into the original bounding box.
Choose UV Editor > Menu > UV > Pack Islands
Then change "Pack To" to "Original bounding box"
Face Nearest only works with individual projection, so always set the
`SCE_SNAP_PROJECT` flag in this case.
Also gray out the `Project Individual Elements` option in the UI if
`Face Nearest` is enabled.
And change the description to indicate that `Project Individual Elements`
is always enabled with the `Face Nearest` option.
(I feel a better design for this option needs to be considered).
Avoid introducing another `::modifiers` namespace for now, since it's
not clear if we'll want that long term. This just avoids a bunch of
boilerplate and makes things easier to read.
Use the node group and the properties as arguments instead of
the modifier. This may help to allow reusing the functions outside
of the modifier execution context.
This adds the select more/less operators to the weight paint mode face selection.
Just like in edit mode, press `CTRL`+`Numpad Plus/Minus` to use them.
They have also been added to the `Select` menu.

When retrieving the evaluated mesh to paint on, it can be reevalauted,
where a smaller set of attributes are requested than for regular
evaluated meshes. That reevaluation should be completely removed
(see #106186), but a simple fix in the meantime is to manually
request that data.
When normalization is enabled in the Graph Editor,
the area outside the -1/1 range on the y axis isn't meaningful.
To visually represent that this patch greys out that area
just as it does with anything outside the current frame range.

fast_float.h currently is only used by OBJ, STL and PLY I/O importers.
Update it to the latest release from upstream (from 3.4.0 2020 Nov to
4.0.0 2023 Mar).
No behavior changes, but they have optimized the performance a bit.
Importing a 6-level subdivided Suzanne OBJ file (330MB) goes from 3.5sec
down to 3.2sec on Win10, Ryzen 5950X, VS2022 build.
Previously, fractional scaling was detected but set an integer buffer
scale which the compositor would down-scale causing blurry output.
Now the fractional scaling interface is used when available to set the
DPI and set the internal buffers size & viewport transformation to
ensure 1:1 pixels from Blender to the Wayland output.
Tested to work with multiple monitors with mixed
fractional/non-fractional scale.
Note that this change causes a regression for when fractional scaling
is set on a compositor without support for fractional-scale-v1.
Supporting fractional scaling in both cases is possible but overly
complicated. This case already wasn't working so well - with blurry
output due to image scaling, now the DPI wont be accurate in this case
although Blender is still usable.
