It was a stupid mistake with the wrong pointer being referenced.
It was a serious problem because the memory leak was considerable.

I'm not very fond of adding new types of bvhtrees.
But this is probably the most efficient solution.

While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Free the BVH tree immediately along with the mesh, otherwise we might access
invalid mesh data.

There is no point having operations that iterate over the whole
bit array as macros, so convert BLI_BITMAP_SET_ALL to a function.
Also, add more utilities for copying and manipulating masks.

Helps separate variable names from descriptive text.
Was already used in some parts of the code,
double space and dashes were used elsewhere.

multiple objects.
- Use the object referenced in `BMEditMesh` as the `ghash` key to save the bvhtrees in cache;
- Create a boundbox around edit_mesh to test the snap before creating bvhtree;
- Save the `edit_mesh`s bvhtree in the mesh bvh_cache;
This is a part of the D3504.

This prevents zero-leafs bvhtrees from being recalculated multiple times.

Same issue as in DM-based on, so follow up of rBf3efa9e15f58...

Could lead to atempt to free NULL pointer, and/or memory leak.

BLI_bvhkdop functions were not made to work with zero-leaf trees.
Perhaps a better solution would be to modify BLI_bvhkdop to work with zero leaf trees.
But this solution of returning NULL was already used for bvhtrees of looptris.

This member currently doubles the value of `ray->radius` or is not even used.

This will help us have more control over bvhtrees that are cached.

|
This will allow greater control of the bvhtrees that are obtained, and helps identify problems.
It is also an additional step to unify the functions.

- When returning the number of items in a collection use BLI_*_len()
- Keep _size() for size in bytes.
- Keep _count() for data structures that don't store length
(hint this isn't a simple getter).
See P611 to apply instead of manually resolving conflicts.

arrays again from DM.
This was... horribly wrong, CDDM will often *not* need to allocate
anything to return arrays of mesh items! Just check whether array
pointer is NULL.
Also, remove `DM_get_looptri_array`, that one is useless currently,
`dm->getLoopTriArray` will always return cached array (computing it if
needed).
|
|
Also remove duplicate & mismatching comments from grease-pencil header.
Keep comments close to implementation to avoid getting out of sync.

of bvhutils
The release of these arrays should be the programmer's discretion since these arrays can continue to be used.
Only the expanded functions `bvhtree_from_mesh_edges_ex` and `bvhtree_from_mesh_looptri_ex` are currently being used in blender (in mesh_remap.c), and from what I could to analyze, these changes can prevent a crash.
