NanoVDB is a platform-independent sparse volume data structure that makes it possible to
use OpenVDB volumes on the GPU. This patch uses it for volume rendering in Cycles,
replacing the previous usage of dense 3D textures.
Since it has a big impact on memory usage and performance and changes the OpenVDB
branch used for the rest of Blender as well, this is not enabled by default yet, which will
happen only after 2.82 was branched off. To enable it, build both dependencies and Blender
itself with the "WITH_NANOVDB" CMake option.

This has serious performance implications as the additional check makes
it O(N^2) when there are a lot of merged vertices.
The goal is to move the merging to the weld modifier where it would
be much easier to optimize.

This commit to complex solidify swaps the side of the geometry which
is affected by the material offset when the normal flip option is
enabled. This matches simple solidify and is considered correct/useful.

Apply the De Casteljau algorithm to split the Bèzier curve at the X
coordinate where the new key is inserted, and uses the result to update
both the newly inserted and surrounding handles.
For curves that use Auto keyframes this has been largely addressed by
the new algorithm from D2884. This commit extends this to non-auto
handles.
This code is heavily based on D3172 by Alexander Gavrilov (@angavrilov).

Initialize CLOG in the blendfile-loading unit test superclass. Since
rB8683d4e88f2e CLOG is used by more areas in Blender, and without
initialisation it crashes.
Current libmv_modal_solver_test fails since rB3a7d62cd1f5e.
It appears that the issue is caused by the insertion of the new OFFSET_K4 parameter,
as, if camera intrinsics are not required to implement/use all of those deform
parameters, they absolutely have to keep order (values) matching those defined
in bundle.cc, otherwise `PackIntrinisicsIntoArray` and `UnpackIntrinsicsFromArray`
will mangle them around.
This reverts commit 66cd82a8d. This was based on a misunderstanding. We do want
to take into account transforms similar to other modifiers like booleans, to
support taking into account animated transforms, combining multiple meshes into
one volume, etc.
Declaring variables where they are initialized and used makes their
scope much more explicit and it aids readility since types are visible.
This commit doesn't touch the ID template code since there is an
active patch in that area.
This is first step of refactoring task T77580.
Next step will be breaking up files into smaller ones.

Functionality was hard to follow as the meaning of fullname
depended on basename being NULL or not.
- where_is_temp is now only responsible for finding the temp directory.
- Split out tempdir_session_create into it's own function
that wraps mkdtemp.
- Rename basename to tempdir, fullname to tempdir_session.
This choice was made when preferences were not read in background mode,
so the temp dir needed to be initialized with something.
See bc9848f7e6.
Now preferences are always read there is no reason to ignore this
particular preference in background mode.
Anyone wanting to do background renders that ignore their preferences
can run with factory startup.
These were printf's, disabled by a define that could be uncommented.
Use logging since this can be useful when investigating any issue
with paths not being found at the expected location.
Without this any problem finding app-templates, Python's installation,
icons ... etc are quite difficult to troubleshoot especially on systems
without access to system-call tracing.
To use this run:
blender --log "bke.appdir" --log-level 3
Initialize ImBuf (and color-management) after passing arguments
that set environment variables such as `--env-system-datapath`
This also fixes a bug where BKE_appdir logging failed since it was
called before the `--log` argument was passed.
Add asserts so this doesn't happen again.
Internally appdir functions would test if a path exists,
returning false if it doesn't, leaving the string set instead
of clearing it.
This is error prone as invalid paths could be used accidentally.
Since BKE_appdir_folder_id_user_notest & BKE_appdir_folder_id_version
depend on this, add a 'check_is_dir' argument so the path can be used
even when the directory can't be found.
Actually, fixes compile error and an incorrect poll.
Caused by 21fc4ae206 and 3a1cf838ca.
The poll has to perfrom the `view_zoom_poll()` logic to ensure correct context.
Uncovered by a4aa94c41c. Before that, it would actually be a possible `NULL`
pointer dereference.
It would happen if a `UILayout.prop()` was placed with the `full_event` option
set to `True` (or the C equivalent) for a non keymap-item property.
Now this the `full_event` option is ignored then with a warning print.
Multiple related issues:
* `view_zoomdrag_exec()` required `view_zoomdrag_init()` to be called first to
set up data. Can now easily be done in the `_exec()` function as well though.
* Because of that the operators could not be called in an `EXEC_` context (e.g.
`EXEC_REGION_WIN`).
* With "Zoom to Mouse Position" enabled, zooming from a menu or script would
zoom to the mouse position. That should only happen if the operators are
called directly in the editor.
`view_zoomdrag_init()` would perform a number of sanity checks that
`view_zoom_poll()` already executed. The design of operators forsees that
(non-expensive) context sanity checks are done by the `poll()` callbacks, and
the execution callbacks can then just assume that happened. No reason to be
overly pedantic, we don't do that elsewhere either.
Note that this code is from the earliest days of an operator design. So it's
not surprising that it wasn't using the design "properly".
This commit makes the panel expansion set based on the search results
when the active tab in the properties editor changes. The multi-tab
search patch (D8859) actually doesn't handle this because it uses a
different code path.
This feature uncovered a subtle but fairly significant issue with the
implementation of property search (More details in T81113). Basically,
the search needed multiple redraws to properly display the expansion of
panels based on the search results. Because there is no animation of
panel expansion when switching tabs, the problem was exposed only now.
With this commit, hiding of "search only" buttons and panel size
calculation happens in a single final step of the panel layout pass.
The "search only" layout root flag is removed. Instead every button
inside a panel header is in a single "uiButtonGroup" marked with a
specific "in header" flag, an idea which could be generalized in the
future.

Change `test_path` function so:
- Joining paths calls a function instead of being performed inline.
- Optional NULL paths must always be ordered last (easier to follow).
Other minor changes:
- Remove FIXME comment is it's handled properly by BLI_path_join.
- The wrong size was being used copying into `targetpath`.
We have our own assert implementation, `BLI_assert()` that is prefered over the
C standard library one. Its output is more consistent across compilers and
makes termination on assert failure optional (through `WITH_ASSERT_ABORT`).
In many places we'd include the C library header without ever accessing it.
Revert 76b1a27f96 since there is no
reason windows should behave differently to other platforms.
This was added so Windows users wouldn't see "/tmp/" in the UI.
Since then the default temporary directory is a blank string,
leave blank on all systems as Python script authors may accidentally
use this instead of `bpy.app.tempdir`.
