This matches the change that was done to the bevel modifier so that the
interface for the modifier, the active tool, and the operator are consistent.
This commit extends the refactor to the bmesh implementation too, so
that the parameters in the implementation don't stray too far from what
is exposed.
Tests are adjusted and still pass.
Both to_v and form_v need to be included. From_v is needed to include
the active vertex when there is only one vertex in the radius of the
brush, to_v needs to be included to add all grids duplicates

Implementation of lerp without a function requires repeating one of
the arguments, which is not ideal. To avoid that, add a new function
to the driver namespace. In addition, provide a function for clamping
between 0 and 1 to support easy clamped lerp, and a smoothstep function
from GLSL that is somewhat related.
The function implementations are added to a new bl_math module.
As an aside, add the round function and two-argument log to the
pylike expression subset.

Object sockets work now, but only the new Object Transforms and the
Particle Mesh Emitter node use it. The emitter does not actually
use the mesh surface yet. Instead, new particles are just emitted around
the origin of the object.
Internally, handles to object data blocks are passed around in the network,
instead of raw object pointers. Using handles has a couple of benefits:
* The caller of the function has control over which handles can be resolved
and therefore limit access to specific data. The set of data blocks that
is accessed by a node tree should be known statically. This is necessary
for a proper integration with the dependency graph.
* When the pointer to an object changes (e.g. after restarting Blender),
all handles are still valid.
* When an object is deleted, the handle is invalidated without causing crashes.
* The handle is just an integer that can be stored per particle and can be cached easily.
The mapping between handles and their corresponding data blocks is
stored in the Simulation data block.
Adjusting the layout for this modifier is the final part of the modifier UI
project for 2.90. This layout exposes the most important information,
the levels and subdivision controls, by default, putting other contols
in collapsed subpanels.
Note that there is empty space for the "Delete Lower" button
that is still planned for 2.90. And there will also eventually be more
items added to the "Shape" panel, maybe for 2.90.

Operators are one of the last places in Blender to use older UI designs
that don't fit in with recent style conventions. This commit updates
these custom operator UI callbacks for consistency and clarity.
Some of the code is also simplified a lot. Some of the older operator layouts
were much more complex (in terms of code) than they needed to be.
See the differential revision for a before and after screenshot
of each operator.

Currently if you drag and drop an item from the outliner elsewhere in
the Blender window, the outliner will scroll the entire time, even if the
mouse is far away. This commit adds optional behavior for the edge pan
operator that makes it only act if the mouse is close enough to the region.

When overriding a whole linked collection from a single object in
3DView, said 'reference' object would be removed by code. We only want
that behavior when overriding from an instanciating Empty.
It looks like the code left this as a todo, but the basic solution is to
add an extra parameter to BKE_bose_rest to check whether bones
are selected before reseting them.
I also corrected the operator description which said it acted on only
selected bones even when there is an option to turn that off. The
"act on selected" is generally implied for Blender's operators anyway.

The function is called for all writers, not just 'object' writers.
Furthermore, it's called by the function `release_writers()`, so now the
name is consistent with that as well.
No functional changes.
The unit tests for `bf_io_common` didn't actually link against
`bf_io_common`, so when both USD and Alembic were disabled, nothing
would link against that library and building the tests would fail.
Any time FFmpeg was used to get a picture Blender would crash
when FFmpeg 4.3 is used. This affects thumbnails, VSE, Clip Editor.
Caused by a bug in FFmpeg which lead to crashes when unaligned
buffer was passed to sws_scale(). It got fixed later on in FFmpeg,
but for portability and compatibility reasons still nice to avoid
crash, especially since it's not so difficult to do.

Previous ones were extremely confusing and innacurate (probably
inherited from older versions of scene collections?).
Also, use named fields in struct initialization, much much safer and
cleaner than anonymous, positionned-based thing.
Added support for transforming only origins with greasepencil objects.
The new functions is based on BKE_gpencil_transform. That is why there is FIXME statements in there.

Internally UV selection considered close UV's to be connected.
While this could be convenient in some cases,
it complicates logic for more advanced selection operations that
need to check when UV's should be considered part of the same vertex
since simple threshold checks would give different results depending
on the order of UV's tested.
Users must now run "Merge by Distance" instead of relying
on this selection threshold.
There was a weird looking gap between the checkbox and the "Motion Tracking"
label. Plus, the label could not be clicked to change the value, unlike
usually.
Issue is that the row is actually a sub-panel header. The checkbox being drawn
with the draw_header() callback, and the label being added as separate item by
the popover panel code. This adds a hack so the checkbox can add the panel
label itself (the popup drawing skips adding the label then). That addresses
mentioned issues.
The sky will appear brighter than before by default. To compensate for this,
lower exposure in the Film panel. The default altitude was also changed from
90 to 15 degrees.

Trying to get shape key pointer after having unlinked its owner from
Main data-base is rather useless... So those shapekeys ended up never
being deleted.
This refactor is in response to reports in which the adaptive domain with noise caused a crash (e.g. T79009). It should also fix issues where the smoke appeared to be cut off when using the adaptive domain together with noise. It is also possible that some of these changes improve the lines issue from T74559.
This was caused by `BPy_*_ALLOW_THREADS` being used when it shouldn't.
Implemented the simple fix suggested by @brecht :

That project cannot be opened correctly ayway, it has recursive
collections intanciating themselves...
But at least now we have a check at startup to detect and 'fix' those
nasty cycles in collections.
Those are useful when you have to create containers with static
storage duration. If those would use Blender's guarded allocator,
it would report memory leaks, that are not actually leaks.
Analyzing the cuts, the points shown in the viewport (indicating the
previous and current cuts) do not correspond to the final cuts.
Sometimes a point, even snapped to a vert, is a point that cuts an edge and
sometimes a point, even snapped to an edge, is a point that cuts only the face.
This is because the detection of snapping vertices from mouse is different
from the "snap" that detects vertices that are cut.
So small projection inaccuracies can result in detection failures.
The solution for this is simply to confirm the cuts whose vertices
indicate the `prev` ou and `cur` point.
The tolerance distance does not need to be calculated in these cases.
This updates the usage of integer types in code I wrote according to our new style guides.
Major changes:
* Use signed instead of unsigned integers in many places.
* C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`).
* Hash values for C++ containers are 64 bit wide now (instead of 32 bit).
I do hope that I broke no builds, but it is quite likely that some compiler reports
slightly different errors. Please let me know when there are any errors. If the fix
is small, feel free to commit it yourself.
I compiled successfully on linux with gcc and on windows.
Custom driver functions need access to the dependency graph that is
triggering the evaluation of the driver. This patch passes the
dependency graph pointer through all the animation-related calls.
Instead of passing the evaluation time to functions, the code now passes
an `AnimationEvalContext` pointer:
```
typedef struct AnimationEvalContext {
struct Depsgraph *const depsgraph;
const float eval_time;
} AnimationEvalContext;
```
These structs are read-only, meaning that the code cannot change the
evaluation time. Note that the `depsgraph` pointer itself is const, but
it points to a non-const depsgraph.
FCurves and Drivers can be evaluated at a different time than the
current scene time, for example when evaluating NLA strips. This means
that, even though the current time is stored in the dependency graph, we
need an explicit evaluation time.
There are two functions that allow creation of `AnimationEvalContext`
objects:
- `BKE_animsys_eval_context_construct(Depsgraph *depsgraph, float
eval_time)`, which creates a new context object from scratch, and
- `BKE_animsys_eval_context_construct_at(AnimationEvalContext
*anim_eval_context, float eval_time)`, which can be used to create a
`AnimationEvalContext` with the same depsgraph, but at a different
time. This makes it possible to later add fields without changing any
of the code that just want to change the eval time.
This also provides a fix for T75553, although it does require a change
to the custom driver function. The driver should call
`custom_function(depsgraph)`, and the function should use that depsgraph
instead of information from `bpy.context`.
