194e233d86 caused a discussion in the chat about the initialization
behavior of `MEM_new()`, and agreement was to not rely on
zero-initialization ever. Noted this in the API comment now.
Some people found the existing comment useful but it still left some
questions. Tried to clarify that now.
This is a crucial memory management function, it's important to have
behavior documented well, even if a full explanation is out-of-scope.
Also added another link in case people want to check more details.

The compositor leaks memory in certain setups where a transformed result
is linked to two inputs in the same pixel node. This happens due to an
overestimation in the computation of reference counts of those results.
Since pixel operations might share the same input for multiple links in
the node tree, the reference count should be corrected to take that
sharing into account.
This sharing was previously accounted for as part of releasing inputs in
the pixel operation, but input processors didn't take that into account,
so the realize on domain input processor would leak memory. So to fix
this, we correct the reference count at the evaluator level instead,
such that input processors can safely operate on the correct reference
count.

This avoid the dependency on the draw module and remove the
access to a global variable.

All 2D vectors related to image transform code were changed to float2.
Previously, it was decided, that 4x4 matrix should be used for 2D
affine transform, but this is changed to 3x3 now.
Texture painting code did rely on `IMB_transform` with 4x4 matrix.
To avoid large changes, I have added function
`BLI_rctf_transform_calc_m3_pivot_min`.
Main motivation is cleaner code - ease of use of c++ API, and avoiding
returning values by arguments.

Fixed use of lists using multiple arguments - `list` only
support a single argument.
Noticed working with fake-bpy-module - providing multiple
arguments to `list` resulted in typing error (e.g. "Too many type
arguments provided for "list"; expected 1 but received 2").

The main issue was that the code was using
`foreach_editable_drawing_with_automask` which shouldn't have been
the case since there is no "masking" to be done when pasting strokes.
Additionally the code was computing the view position of every
pasted point and then computing the offset to move the points to the
mouse position.
Instead, we compute the center of the 3d bounds of the pasted strokes
and then project only the center to the view. From there we can offset
all the points to move them under the mouse cursor.
It's a bit weird to do this projection of the center to the view and
I believe we mainly do it to reuse the `DeltaProjectionFunc`.
There are cases where the projection of the center to the view will fail
which can lead to unexpected behavior on the user end. For now we
just leave the pasted strokes where they were copied from, which
isn't ideal. But this can be improved later.

The vulkan backend was implemented with async in mind, however the one place
where Blender uses for async was implemented blocking. This PR splits the
readback into flushing the command and waiting for readback.
**Performance**
Improvement of animation playback performance of shader balls.blend is around 10%.

This ends up being very simple because point cloud has
no connectivity information and each element is just one
position.
Also implement the 3D transform gizmo.
The geometry deformation system isn't implemented in this
commit. That can be tacked later.
Avoid calling `GPU_indexbuf_add_line_verts` and the triangle
version of that function. It's faster to avoid function calls and
just write to the data arrays directly. I did some very rough tests
and observed about a 10% improvement in runtime for the
entire index buffer creation process.
This patch modifies the logic behind handling NDOF device events on
macOS so that it can benefit from the `Blender` profile available in
3DConnexion driver v10.8.7 and later.
A new device command was introduced: `kConnexionCmdAppEvent`, which is
sent by the driver upong getting an apprioriate NDOF device button
input. This allow the driver to consumes all NDOF device input and then
send appropriate app events based on its configuration instead of
forwarding raw data to the application directly.
When using 3DConnexion driver versions prior to v10.8.7, the behavior
is unchanged. This approach allows for supporting all of the SpaceMouse
Enterprise buttons, long presses included (solving issue #119206 on macOS)

The warning to check if two numbers are nearly equal when comparing
floats didn't take negative numbers into account, causing -1.0 & 0.0
for e.g. to be considered not equal but close.
This also resolves a divide by zero.
