The GPU compositor Displace node produces NaN pixels if connected to the
Image node. That's because the Displace node access the MIP levels of
the texture produces by the Image node, but those levels were never
initialized, so fix this by completing the levels.
The issue was caused by Cycles doing dependency tracking on its
side, relying on the fact that view layer needs to be tagged as
modified when its properties change.
This was not the case when custom property on the a view layer is
modified via a driver.
Now the dependency graph will tag IDs which generic properties did
change as ID_RECALC_PARAMETERS, giving it a chance to render engines
to react to it.
Since this is quite generic code which might have unforeseen side
effects the change is not targeted to the current release branch.
Note that this chaneg does not fix the #103140, as the issue there
is use of RNA path to another data-block, without the node tree
registering relation to that data-block.

Move BLI_convexhull_aabb_fit_points_2d to a public function to be able
to compare compare fitting one convex hull with a simple reference
method.
One test is disabled as it exposes an error in convex hull calculation
which needs further investigation.
The result of cross_poly_v2 was flipped compared with cross_tri_v2 &
cross_poly_v3 (with the Z values zeroed).
Ensure cross_poly_v2/3, cross_tri_v2/3 return compatible results and
updating the doc-strings noting that a negative Z is for clock-wise
polygons.
This adds two new constructors to `IndexMask`:
* `from_repeating(mask_to_repeat, repetitions, stride, initial_offset, memory)`:
It allows repeating an existing index mask with a stride.
* `from_every_nth(n, indices_num, initial_offset, memory)`: Creates an index
mask like `{0, 2, 4, 6, ...}`.
`from_every_nth` is implemented in terms of `from_repeating` which is optimized
to handle this case (and other cases) very efficiently.

The iterations through the rows and columns where flipped.
This would cause invalid memory to be accessed and an assertion
error in debug mode.
Note: This is only fixing an error with non-square matrix printing
and has no effect on square matrices.

When calculating the width of strings for the tooltip window size, enum
labels were measured using the string from the text_suffix field but
length from the text field. Introduced with std::string changes.

An allocated char pointer was reassigned without being freed.
Fix by replacing the error-prone combination of C strings and
std::string with a complete conversion to std::string. Also change
the logic a bit to allow moving the path string in some cases
instead of copying it.

After bb080140c0, `SCULPT_pbvh_calc_area_normal` returned
std::nullopt when it didn't sample any vertices, instead of returning
an ignorable boolean return value. There was a false negative failure
though, because it didn't keep track of when it sampled BMesh "orco"
vertices.
5 years ago (18b693bdbd) part of cache rendering was converted to not
draw one quad at a time. However the other part (drawing strip
backgrounds when cache visualization is on) was left still drawing one
quad at a time.
Now that sequencer timeline drawing code has SeqQuadsBatch that batches
arbitrary number of things for drawing fairly easily, the existing
cache drawing batching code can be simplified to just use that, and
the background code changed from immediate quad drawing to use the
batcher.
Sprite Fright edit, whole timeline visible, all caches visualized and
full: `draw_cache_view` on Windows/Ryzen5950X goes 2.40ms -> 0.16ms.
And there's less code.

Make the 'purge' operation show an interactive popup by default, with
a preview of the type and amount of data-blocks to be deleted.
Idea and initial UI/UX design are from @Harley (see PR !117242).
Pull Request: https://projects.blender.org/blender/blender/pulls/117304
Add a new `BKE_lib_query_unused_ids_amounts` to query expected amounts
of deleted IDs. This function does not tag IDs in main anymore.
Factorize most parameters (and output data) into a new struct
`LibQueryUnusedIDsData`.
