The last point of the output was at the same location as the
first point of a cyclic spline. The fix is simple, just account for
the cyclic when choosing the sample edge length, and don't
hard code the last sample.
The spline `length` function assumed that the curve always had evaluated
edges. That is clearly false. This commit adds a check to `length` and a
special case for a single point in the curve resample node.
This commit uses two changes to improve the performance of the point
instance node.
**Prevent Reallocations**
At 64 bytes, the transform matrix for every instance is rather large,
so reallocating the vector as it grows can become a performance bottle-
neck. This commit reserves memory for the instances that will be added
to prevent unecessary reallocations as the instance vector grows.
In a test with 4 million instances of 3 objects in a collection, the
node was about 40% faster, from 370ms to 270ms for the node.
**Parallelization**
Currently the instances are added by appending to a vector. By changing
this slightly to fill indices instead, we can parallelize the operation
so that multiple threads can fill data at the same time. Tested on a
Ryzen 3700x, this reduced the runtime from the above 270ms to 44ms
average, bringing the total speedup to ~8x.
Note that displaying the instances in the viewport is still much slower
than the calculations in node, this change doesn't affect that.
This patch refactors the instance component to make use of the earlier
refactoring in rB4599cea15dcf. Now we don't have to build an array of
instance references the size of the point domain, and we can gather the
possible instances only once and use the same vector for all component
types. Generally the node should be a bit faster and use less memory.
The logic is moved around a bit, especially the hashing of the ID
attribute to pick from the instance list, but the result is unchanged.

Those were mostly just left over from previous work on particle nodes.
They solved the problem of keeping a reference to an object over
multiple frames and in a cache. Currently, we do not have this problem
in geometry nodes, so we can also remove this layer of complexity
for now.
We need to always add a single point to the last cyclic segment that
completes the loop, because that includes the starting point of the
evaluated edge. The existing code forgot about that point.
This node generates a naturally parametarized (even length edge) poly
spline version of every spline in the input. There are two modes,
"Count", and "Length". These are similar to the same options for the
line primitive node in end points mode.
I implemented this instead of a "Sample Points" node, because for this
operation it's trivial to keep the result as a curve, which is nice
since it increases flexibility, and because it can make instancing
simpler, i.e. using the transforms of each evaluated point rather than
requiring the construction of a "rotation" attribute.

Now it's possible to append materials of one grease pencil object into another one. The operator allows active material or all materials.
Also, the Layer Copy To Object has been renamed to Layer Append to Object to keep consistency and now allows to append all layers at once.
Small addition inspired by [this tweet](https://twitter.com/Vorundor/status/1390645286624763909) of a user in a situation I also saw myself in the past.
Showing "(Clipped)" next to the view name in the `Text Info` overlay fits well since it's a per-viewport setting.

this is a followup to rB2bd85d9cc623, we cannot forcefully delete
obsolete overrides of object data (meshes etc.), as this implies also
deleting their user object, which might still be a perfectly valid
override, albeit in conflict regarding its obdata ID pointer...
This is the opposite of previous code, which would keep those
'deprecated' overrides arround (often in a dedicated collection), when
they were detected as user-edited.
While this is a safe-ish way to (try to) preserve user-edited data, this
tends to add too much 'trash' data to production scenes, which cleaning
becomes a burden.
Note that user will get warnings in thos cases, and can always choose
not to save the current blend file and go fix the library issue instead.
Code detecting overrides which reference linked data is missing was
actually missing many cases, leading to too much garbage data being kept
around after resync process.
This iterator design provides means to create simple and flexible API
to query and work with collection of strips. It should be used in cases
when conditions require multiple stages of recursive iteration of all
strips or similar complex scenarios.
Quick API overview:
Basic queries are standalone functions that return SeqCollection
Use SEQ_collection_create() and SEQ_collection_free() to construct
such query functions.
Use these functions to get strips of known conditions, like selected
strips, movie strips, muted strips and so on.
Use SEQ_reference_query() when querying strips with relation to
some reference strip. For example to get its effects, strips that have
same type or use same input file and so on.
These aren't standalone functions because often you need to query strips
relative to each strip in collection.
Use SEQ_collection_expand() to query strips relative to each strip
in collection. These will be merged to original collection.
Use SEQ_collection_merge() to merge 2 collections
To iterate collection elements use macro SEQ_ITERATOR_FOREACH()
This API is quite specific, but I think it is best suited for tasks
that are usualy solved in sequencer codebase.
Old sequencer iterator has been completely removed.
SEQ_ALL_BEGIN and SEQ_ALL_END macros re-use new iterator design.
As initial use for this iterator select_grouped_effect_link()
function has been rewritten. It was not only broken, but also it used
DNA fields to aid iterating strips.

Instead of only drawing images on first start, load them into cache.
This resolves a logical problem when images don't load fast enough,
where the animation would load some frames each time until all images
loaded into cache.
In practice this could play back with severe frame skipping many times
times before all images were loaded making playback smooth.
Part of a fix for T81751.
