Since add-ons now unregister on exit
(as of fa566157a5)
clearing functions in `bpy.app.handlers` caused an error on exit.
Resolve by restoring handlers before exiting.
When an projecting onto a plane that is orthogonal to the views Z axis,
project onto a view aligned axis then map it back to the original plane.
see: ED_view3d_win_to_3d_on_plane_with_fallback
Since the depth can't be properly visualized in 3D, display a 2D so
it's possible to to tell the depth from the cursor motion.
When using surface orientation and nothing is under the mouse-cursor,
pick the axis that's closest to the view's Z axis.
Now by default default, drawing into empty spaces wont use a plane
orthogonal to the view.
Generating the thumbnail left the view matrices set to values
that couldn't be used for cursor drawing.
Backup/restore the matrices for off-screen drawing.
The Normal Map node was falling back to (0, 0, 0) when it was missing
the required attributes to calculate a new normal.
(0, 0, 0) is not a valid normal and can lead to NaNs when it is
normalized later in the shader. Instead, we now return sd->N,
the unperturbed surface normal.
The issue was that the same point cache was read by multiple
threads at the same time (the same object was evaluated for
render and for the viewport).
Both threads incremented PTCacheMem->cur which lead to the crash.
The fix is to remove the PTCacheMem->cur and store it on the
stack instead. This way every thread has its own cur.

Cover all atomic functions with unit tests.
The tests are quite simple, nothing special so far. The goal is to:
- Make sure implementation exists.
- Implementation behaves the same way on all platforms
(We had issue when MSVC and GCC were behaving differently in the
past).
- Proper bitness is used for implementation and non-fixed-size
function implementation.
The tests can be extended further to make sure, for example, that
CAS operations do not cast arguments to a more narrow type for
comparison. Considering it a possible further improvement, as it is
better be done being focused on that specific task.
There is an annoying ifdef around 64bit implementation, which uses
same internal ifdef as the header does. This check is aimed to be
removed, so is easier to simply accept such duplication for now.
The tests seems somewhat duplicate for signed/unsigned variants and
things like this. The reason for that is to keep test code as simple
as possible: attempting to do something smart/tricky in the test code
often causes the test code to be a subject of being covered with its
own unit tests.

Previously the lock-free tests were actually testing guarded allocator
because the main entry point of tests was switching allocator to the
guarded one.
There seems to be no allocations happening between the initialization
sequence and the fixture's SetUp(), so easiest seems to be just to
switch to lockfree implementation in the fixture's SetUp().
The test are passing locally, so the "should work" has high chance
of actually being truth :)
Differential Revision: https://developer.blender.org/D9584
Previously the only way to use lockfree implementation was to start
executable and never switch to guarded allocator.
Surely, it is not possible to switch implementation once any allocation
did happen, but some tests are desired to test lock-free implementation
of the allocator. Those tests did not operate properly because the main
entry point of tests are forcing guarded allocator to help catching
bugs.
This change makes it possible for those tests to ensure they do operate
on lock-free implementation.
There is no functional changes here, preparing boilerplate for an
upcoming work on the allocator tests themselves.
Don't refresh the list of sockets, so that when the .blend file is restored the
links remain valid. Also display such nodes in red to indicate an error, same
as when the node type info is missing.
Some DNA headers already did this, most did not. Even though many of them would
be included in C++ files and thus compiled as C++. This would be confusing and
developers may think they have to add `extern "C"` too a whole lot of
(indirect) includes to be able to use a C header in C++.
However, this is a misconception.
`extern "C"` does not cause code to be compiled with C rather than C++! It only
causes the linker to not use C++ function name mangling. See
https://stackoverflow.com/a/1041880.
Because extern DNA headers don't have function declarations, using `extern "C"`
actually should not have any effect. On the other hand, adding it causes no
harm and avoids confusion. So let's just have it consistently in C header
files.

Don't allocate StripElem for movieclip, scene and mask strips. This
struct is not handled in seq_dupli function. This caused field to be
uninitialized in COW datablock.
StripElem is not allocated when adding strip with operator and it is
not needed for these strip types.

Split up the Euler filter function into two more functions. The Euler
filter operator works in two stages (find channels that define the X/Y/Z
Euler rotations, and perform filtering on those channels), and each
stage now has its own function. This makes it clearer which data are
used in which part of the code, and makes future improvements easier.
No functional changes.
This is actually a user interface issue, introduced on 0688309988.
but->tip is checked for NULL in other parts, and rightly so, since here
it crashes Blender.
On a side note I don't know how to reliably reproduce the original bug
whose fix introduced this issue. That got on the way of seeing whether
this is the correct fix, if it happens outside greasepencil operators.
Maybe it is an operator that is missing a tooltip? Impossible to tell
without more information from said commit. That said since this happened
during the end of bcon3 and we are not in bcon4 I'm going ahead with
this NULL check commit.
Patch reviewed by Philipp Oeser and Sergey Sharybin.
Code was rewritten to work on per-sequence basis returning reference to
created strip.
There should be no functional changes.
Selection logic is left as is for now. I could simplify it, but it
belongs to operator, not split logic.

My last cleanup commit for this function missed this case. It likely
happens because the panel's block size doesn't update properly somewhere.
Short of investigating that right now, it makes sense to return early
in this case anyway.
This option joins any stroke with an end near the actual stroke. Now it is not limited to the last stroke, any stroke in the same layer for the actual frame can be joined. The join can join two strokes drawing a third stroke.
If the end and the start of the result stroke are very small, the stroke is changed to be cyclic automatically.
There is a limit distance to join the stroke, if the distance is greater than this value, the strokes are not joined. Actually, a constant, threshold distance is used, but we could expose
as a parameter in the UI in the future.
The tool can be used with freehand drawing or with primitives.
Note: Great part of the patch is just a refactor of the old code to make it accessible and to keep code organized.

The existing panel drawing function was a bit convoluted with dependent
conditions in different scopes, redundant and unecessary computations,
and un-helpful naming.
This commit separates the function into two parts, the backdrop and the
widgets. It also improves naming and uses const where possible, and in
general cleans up the code.
There are some slight visual changes, mostly with the placement of the
drag icon, which moves a bit downward to be centered with the triangle
icon. The black rectangle displayed while dragging is also removed.
The logic for separator-spacers (used here for right-alignment) didn't take
region scaling into account. Usually that's not an issue because they are
otherwise only used in headers which can't zoom.

This is an addendum to previous boolean fix, where the object
transformation was "cleaned". Now the operand one is too.
This fixes the issue shown in the video in T82301 when you move
a column around the XY plane with the top and bottom faces
supposedly coplanar with a cube. The transformation matrix when
you do that has a tiny offset in the z component.
