LineArt: Shifting fix for different camera fitting.

FOV was expanded to cover the shifting range,
rather than to precisely cut at the image border. Now fixed.

Fix T91680: viewport selection broken in macOS x86 build with Xcode 13

There is an apparent compiler bug here, tweak the code to avoid it. This did
not affect official builds as we were still using Xcode 12.

Fix T92043: Relax/Push Pose does nothing for quaternion rotation.

As can be confirmed by checking generic code for this operation,
it is supposed to blend between the result of Breakdown based on
actual frame range, and the current pose. However for some reason
the quaternion specific code was blending between the current pose
and the current keyframed pose. This means that the operation does
nothing if invoked without modifying the pose first.

This rewrites the code to match the non-quaternion behavior.

Fix T93563: Crash subdividing with overlapping tri and quad

Fix T93353: Reload Library Override file loses Constraints, take II.

When adding `INSERT` operations over RNACollection items, rna diffing
code did not properly report the properties as not being equals.

This in turn triggered the 'purge unused exiting override properties'
mechanism, thus deleting the exitsting (valid) insert override property
operation.

NOTE: This should also be backported to 2.93, and probably 2.83.

Fix T89564: Spline IK breaks when it is far away from the world origin

The isect_line_sphere algorithm became very imprecise when the line and
the sphere were reasonably far away from the world origin.

This would lead to no intersections being reported even if there was a
guaranteed intersection (line crossing from inside the sphere to the
outside).

To fix this we now use the secant root finding method to get an
intersection point. This is much more stable and robust it seems.

Fix T89081: Freestyle noise seed of zero crash

This leads to division by zero in Freestyle's NoiseShader which also
crashes blender.

Not sure if we really need a do_version patch for old files, as an
alternative we could also force a positive number in the NoiseShader.
This patch does not do either, just force a positive range in RNA from
now on.

Fix T93130: Frame Selected with selected paint mask does not work

This broke with {rB20fac2eca723} (which landed in 2.63), so long
standing bug.

Convention for paint modes is:
- when no paint mask is active, `Frame Selected` will focus the last
stroke
- when paint mask is active, `Frame Selected` will focus the selected
mask faces

To check the right vert coords we have to offset with `mp->loopstart`.

Fix T93117: Texture paint clone tool crash in certain situation

Caused by {rBaf162658e127}, so long standing bug.

When changing clone slots (report involved a quite complicated sequence
of selecting textures and undo -- but I think this could happen in more
situations) code checks for UV of new clone slot.
However, since above commit the slot and the clone slot were mixed up,
so in this case the responsible NULL check (for when no UV is assigned)
wasnt working.
Now correct this (NULL check the clone slot uv -- instead of the paint
slot UV).

note: not sure why low level CustomData functions actually dont do the
name NULL checks themselves (seems like callers are always responsible).

Fix T93338: Curve Guide force field crash

Caused by {rBcf2baa585cc8}.

For Curve Guide force fields to work, the `Path Animation` option has to
be enabled. With it disabled, we are lacking the necessary
`anim_path_accum_length` data initialized [done by
`BKE_anim_path_calc_data`] which `BKE_where_on_path` relies on since
above commit.

Now just check for this before using it - and return early otherwise.
Prior to said commit, `BKE_where_on_path` would equally return early
with a similar message, so that is expected behavior here.

Fix T93194: greasepencil channel lists ignoring collection visibility

Same fix as rB0a3b4d4c64f1, but this time for greasepencil.

To repeat: dopesheet in greasepencil mode was ignoring the temporariy
visibility flag of collections. As a result, even though the dopesheet
was supposed to show animation data of visible greasepencils only was
still showing such data of greasepencils that were hidden by hiding
their collection.

Fix T89260: Eevee crashes with custom node sockets.

Cause of this issue is that Custom Node Sockets info type was
initialized as SOCK_FLOAT when registering. Areas within the core that
would ignore custom socket types by checking its type would use the
socket as being a float type.

When custom node sockets have a property called default_value blender
tries to store it as an internal default value what failed in debug
builds.

This patch will set the socket type to SOCK_CUSTOM when registering a
custom socket type and allow, but skip storage of custom default values.
In this case the default values should already be stored as custom
properies.
