Reversing Bezier handle types and positions would skip the middle point
of curves with an odd number of segments, which is still necessary to
swap in order to avoid changing the curve's shape.
This was an oversight as the matrix multiplication present in original
code was reversed.

This was caused by un-wanted normalization. This is a requirement of
the MikkTspace. The issue is that g_data.N is expected to be normalized
by many other functions and overriden by bump displacement.
Adding a new global variable containing the interpolated normal fixes the
issue AND make it match cycles behavior better (mix between bump and
interpolated normal).
Workaround the issue by adding an intermediate function. This is usually
the case when working with attributes.

This particular GPU driver does not constant fold all the way in order
to discard the unused branches.
To workaround that, we introduce a series of material flag that generates

Fixes issues in importers written in C++ (T100737):
- Materials had one reference count too much. Affected Collada,
Alembic, USD, OBJ importers, looks like "since forever".
- Active material index was not properly set on imported meshes.
Regression since 3.3 (D15145). Affected Alembic, USD, OBJ. Note:
now it sets the first material as the active one, whereas
previously the last one was set as active. First one sounds more
"intuitive" to me.

From the 3DView code has basically no knowledge of collection hierarchy,
so we can either not remap any local usage of linked objects that are
being overridden, or remap them in all their local collections.
The second behavior makes most sense in the vast majority of cases.
Note that this was only an issue when directly linking and overriding
objects, not when doing so through collections.
The case when the query uv is almost on an edge but outside of any
triangle was handled before. Now the case where the query uv is
almost on an edge but inside more than one triangle is handled as well.
If a "rest_position" attribute already existed, potentiall with another
type, the next name "rest_position.001" would be used, which might
even conflict with a name on another domain. Use the C++ attribute
API instead, which has more standard/predictable behavior.
Issue arises when face areas are really large combined with small UV
areas (report has a mesh ~1.5 km), then precission of shorts is
insufficient.
Now use floats instead.
This also removes this negative signed version of the total area ratio
(since with floats it is no longer used).
Thx @brecht for a lot of hand-holding!
NOTE: this is an alternative to D15805 (and quick tests show this does
not introduce the tiny performance hit as D15805 did).

Before 8c25889bb6, subsurf face center tags were stored in each
vertex, so they were always copied to duplicate meshes. Now they are
stored in runtime data though, so they need to be copied explicitly.
The function name "reset_on_copy" is a bit awkward here, so the
tags are copied by the caller.
- PALETTE_OT_color_add: crashed without a brush.
- SCREEN_OT_actionzone: crashed without a window.
- PREFERENCES_OT_studiolight_show: exception when opening prefs failed.
The slide brush requires attachment information on the curves.
Now a warning is shown instead of crashing Blender. The attachment
information can be generated by executing the
`Curves > Snap to Nearest Surface` operator.
It's possible for misbehaving scripts written before 3.3 to reach
this state and crash Blender. With this change, the error is reduced
to a Python exception.

With rBe6a557952ead, concerns were reported about missing updates when
the view is moved other than through the Edge Pan system.
Although the transform operator blocks navigation in general, it is
good to avoid these cases.
The view offset, calculated by the Edge Pan system, only affects the
position of the nodes, but forget to update:
- snapping data
- final value of transform
- values used for custom drawing
Therefore, to avoid having to update a lot of scattered data, the
`transformViewUpdate` utility has been implemented to recalculate input
values when the view changes.
This utility does more than is necessary to fix the bug, but with that,
it can work in any situation.
The calculation was revised to address two issues:
* Discontinuities occurring when detail was a non-integer greater than 2.
* Levels of detail in the interval [0,1) repeating the levels of detail in
the interval [1,2).
This fixes Cycles, Eevee and geometry nodes.

The blendfile_liblink and blendfile_io python tests in debug fired an
assert that WMWinMan object was in Main database, but not in the ID
name map. This was caused by wm_window_match_do going into case 3
there: the new WM list is completely empty, the old list is not empty,
and it was directly using the old/current list (via
wm_window_match_keep_current_wm function), without actually
registering/validating the objects in it through the name map.

Those collections were so far mainly just tagged as fake user (even
though a few places in code already incremented usercount on them).
Since we now clear the fakeuser flag when linking/appending data, ensure
that these collections are preserved by making these usages regular ID

Since rBb100bdca25b1 the parent inverse was always reset in
ED_object_parent (also for just changing the parent type).
This does make sense (since there is no point keeping it when e.g
changing from "Bone" to "Object" or "Vertex" to "Object", for this to
really make sense it would have to be properly recalculated anyways
which does not happen afaict).
The reported issue was that setting the prop to the same value as it was
before (e.g. from "Object" to "Object") would still reset the parent
inverse which was really unexpected since from a user standpoint,
nothing has changed here.
So in case the value does not really change, we now just early out and
skip `ED_object_parent`.
