PBVH_FACES and PBVH_GRIDS do not store faces directly in nodes;
instead they store 'primitives', which are tesselation triangles
for PBVH_FACES and grids (which are per-loop) for PBVH_GRIDS.
Primitives from the same face could sometimes end up in different
PBVH nodes. This is now prevented in two ways:
* All primitives of the same face are given the same boundary
during PBVH build. This prevents them from being swapped
away from each other during partitioning.
* build_sub adjusts the final partition midpoint to fall
between primitives of different faces.
Turns out PBVH drawing and normal mesh batches are not mutually
exclusive inside the draw cache; there are edge cases with modifiers
and instancing where you need both, and forcing one or the other
inside this function leads to memory corruption.
There were quite a few issues here:
* Bad usage of nagic number leading to confusing code
* Forgetting to take into accoun final `NULL` char
* RNA code thinkin `bl_idname` is python version, when it is actually
BL/C version.
Resolve by setting no_muted_links() on Factor sockets.

Make the logic for converting NDOF Z-motion to a scale value more
straightforward. Flipping the Z axis was scaling by negative-time,
now the entire pan vector is scaled by time and the zoom value is
calculated as `scale = 1 - (z * time)` instead of `1 + (z * -time)`.
Although they're equivalent, confusion here caused T100953.
Also clamp the scale (while unlikely, negative scale wasn't prevented).
This operator (Alt + D) allows users to explicitly create a linked copy
of a group node (same current behaviour for the Duplicate operator).
The duplicate operator (Shift + D) now takes the new User Preference
duplicate data option for Node Tree into account. It is by default
disabled, leading to no functional change for users.
Although we could make in the future make this option "on" by default,
to make it consistent with the rest of Blender we do not at the time.

From T101799:
Currently, the count indicator background and color are hardcoded to
black and white in an attempt to maximize contrast, at the expense of
being too prominent even when not needed.
Changing the background color to match the row (or any other element)
background, would make it look like the data-block icon is masked
out, improving readability while not standing out too much.
The circle background color should not have transparency, as it does
now. And the text inside should match the color of the text used for the
parent element (instead of hardcoded white). This should make it look
good in any theme.

In some situations, layers were filled with their default value
when converting from Mesh to BMesh (entering edit mode, for example).
This was caused by the recently added "copy mesh to bmesh" or "merge
mesh to bmesh" custom data functions creating a difference custom
data format than was used for the copying functions used later.
`CustomData_to_bmesh_block` is not robust enough to handle simple
differences in layout between the layout of the source and result
CustomData layers, because it relies on the order of the types and
the number of layers within each type.
As a fix, make the "mesh to bmesh" special case more explicit in
the conversion functions. This makes the difference in the API
smaller, which is a nice improvement anwyay.
Fixes T101796
Currently, the scale node always changes the interpolation of its result
to bilinear. This was done because the scale node does not have an
interpolation option, unlike the Transform node, so a default of
bilinear was assumed. This turned out to be problematic, because in the
pixelation use cases, a nearest interpolation is typically preferred by
the user.
This patch changes the default interpolation of input nodes to bilinear,
makes the scale node keep the interpolation of the input it receives,
and makes the pixelate node changes the interpolation to nearest. In
effect, for non-pixelation use cases, the default bilinear interpolation
will be used, and for pixelation use cases, the nearest interpolation
will be used unless explicitly specified using a node that sets the
interpolation.
Need to initialize the mask drawing overlays when the new space
is created. Otherwise the new space is configured in a way that
the splines are not visible and overlay opacity is 0.
This change fixes the new masking files created. The currently
saved ones need a manual tweak.
The error message when trying to apply a constructive modifier on a curve
object was wrong, "transform" makes no sense in this context.
Thanks Philipp for pointing it out!
This commit replaces the `Mesh_Runtime` struct embedded in `Mesh`
with `blender::bke::MeshRuntime`. This has quite a few benefits:
- It's possible to use C++ types like `std::mutex`, `Array`,
`BitVector`, etc. more easily
- Meshes saved in files are slightly smaller
- Copying and writing meshes is a bit more obvious without
clearing of runtime data, etc.
The first is by far the most important. It will allows us to avoid a
bunch of manual memory management boilerplate that is error-prone and
annoying. It should also simplify future CoW improvements for runtime
data.
This patch doesn't change anything besides changing `mesh.runtime.data`
to `mesh.runtime->data`. The cleanups above will happen separately.

Allows improving performance with BLI_task.hh in draw extraction code.
Threading added in c15a63d21e improved performance by 3-4x
for me, but didn't make a difference until now.
According to information I gathered, ffmpeg seeks internally using DTS
values instead of PTS. In some files DTS and PTS values are offset and
ffmpeg fails to seek correctly to keyframe located before requested PTS.
This issue become evident after hardcoded preseek of 25 frames was
removed and effort went into more precise seeking to improve
performance. It was thought, that this is bug in ffmpeg code, but
after reading some discussions, I don't think it is considered as such
by their developers, see below:
http://ffmpeg.org/pipermail/ffmpeg-devel/2018-March/226354.htmlhttps://trac.ffmpeg.org/ticket/1189
Best solution seems to be to add small preseek value possibly at
detriment of performance, so 3 frames of preseek are applied. Number 3
was chosen experimentally.
Performance impact seems to be insignificant with this change.

Don't add the radius attribute to point clouds by default, since not
having a radius attribute should be a valid state. The radius is only
set when a radius attribute also exists on curves.
When the active selected object in the 3DView is already a local
liboverride, only perform the 'clear system flag' process on selected
objects, there is no point in trying to create an override out of it.
When image data exceeds half float ranges values are set to +/-
infinity that could lead to artifacts later on in the pipeline.
Color management for example.
This patch adds a utility function `IMB_gpu_clamp_half_float`
that clamps full float values to fit within the range of
half floats.
This fixes T98575 and T101601.
- Give functions and variables more descriptive names
- Use references for arguments
- Use tree topology cache to avoid iterating over all links
- Group related code together
Besides texture nodes, which aren't supported anyway, we don't have any
builtin nodes that still use the socket template system, so this can be
removed.
