When copying (`Ctrl+C`) some ranges of points in the same stroke,
the points would still be copied as one stroke and not split into
multiple strokes.
This was a regression in behavior from 4.2.
Now we use the `remove_points_and_split` to split the selected
points into individual strokes.
The issue is that the existing curves did not have an explicitly set radius.
When adding new curves with an explicit radius, the radius of the old curves was
initialized to 0 and thus becoming invisible. This patch changes it so that all
the existing curves do get a default radius. The `radius_for_write` methods is
currently only used in places that overwrite the entire array, so adding the
default there shouldn't affect anything unintentionally.

When calling the `lookup_or_add` functions on `MutableAttributeAccessor`
we need to make sure that the writer is actually created and the call
did not fail.
This fixes many of the instances where we would use an unchecked
attribute writer and potentially crash.

This fixes the (unreported) issue where solo'ing an NLA track would only
play back animation when _any_ of the tracks were unmuted.
Some code considered a track to be muted when its `NLATRACK_MUTED` flag
was set regardless of the `NLATRACK_SOLO` flag, whereas other code did
consider the `NLATRACK_SOLO` flag.
Now all the code is consistent with what actual animation evaluation is
doing.

The UI code assumed buttons had no more than 4 elements
however Python scripts may define larger array sizes.
Resolve the bug by adding functions for array access that take an
array size limit to prevent buffer overflows (read & write).
Note that this only adds the "float" versions of these functions,
for completeness int & boolean can be supported as a separate commit.
A bit less trivial than usual, since it was an 'array' of non-trivial
structs. Used a `blender::Array` instead.
NOTE: keeping changes to a minimum, there is much to refactor and
cleanup in this code.
Add a new callback `setting_post_update` to the `bAnimChannelType`
that gets called after that setting was altered via the channel list
buttons and via `ANIM_channel_setting_set()`.
This is used when changing the NLA track SOLO and MUTE options, to
ensure that the dependency graph relationships get rebuilt.
This fixes#134190.

This implements the memorization of the previous state of a space's
subtype for those that have multiple modes. Introduces an optional
space_subtype_prev_get callback, implemented for SPACE_ACTION,
SPACE_FILE, SPACE_GRAPH, SPACE_IMAGE and SPACE_NODE. This means we
can always return to the previous mode.

Collapsing curves to a single point when just resampling is unexpected. This
patch changes it so that non-zero-length curves keep at least one segment.
The fix is fairly straight forward, but a bunch of additional code is added to
support the legacy option to avoid breaking backward compatibility.

There was a missing call to `BKE_main_ensure_invariants` to make sure that the
node tree is in the expected state. I'm passing the `newid` to the function so
that it can skip iterating over all of `Main` in the majority of cases.

Selection mask is included in the stroke interpolation tool in
297b97f2df, however sometimes there will
be mismatches for when start/end curve count isn't the same. This fix
ensures that the interpolation operator only works on the max amount of
curves that can fit in both start and end side of the interpolation.

Reading & restoring RNA "writable" state wasn't working reliably when
Python was called from multiple threads.
- Resolve by acquiring the GIL before calling `pyrna_write_*` functions.
- Assert `pyrna_write_*` has the GIL to prevent this happening again.
- Move duplicate checks from bpy_props.cc into utility functions.
Translating keys when speed transitions are present with media not
matching scene FPS causes incorrect behavior.
This was caused by multiple issues - in some places media vs scene FPS
mismatch was not accounted for and multiple instances of presision loss
due to casting float values to integer.

Connected strip status is critical information, maybe more important
than strip name. Therefore it should be drawn unless all overlays are
disabled.
This commit makes the icon visible in strip "header" area even if text
overlays are disabled. Content is maximized in this case, and the icon
is drawn over the content.

`bpy.utils.unregister_class(bpy.types.Menu)` would remove `bl_rna`
type information from the menu (also Panels & other built-int types).
Prevent unregistering built-in types since this will only cause problems.
For many selection variations we alter the operator's displayed name to
reflect this. For example "Select (Extend)", "Select (Deselect)", and
"Select (Toggle)". This PR does similar for VSE select modes, returning
"Select (Unconnected)", "Select (Linked Time)",
"Select (Linked Handle)", and "Select (Side of Frame)". These are shown
if you press Alt or Ctrl while hovering in the VSE Editor.

This is due to hardcoded color and subdivision value. Also scale and
offset properties stored in overlay stuct was not considered. Now
multiply the transform matrix with `grid_mat` to make use of these
properties.

Even though from an internal standpoint one could also just use INT
layers (if I understand correctly they are both handled as long?), we
can just support getting/setting bool layers in
the bmesh layer API as well (otherwise, it looks impossible to access
boolean attributes in bmesh).

This `panel->runtime->custom_data_ptr` is `MEM_delete`'d even, so that
was plainfully wrong allocation code.
Will crash in main/4.5 due to PointerRNA now requiring proper C++
construction/destruction.
Use `self` parameter to retrieve the actual 'owner' Main.
Previous code was using G_MAIN, which _should_ be fine in current usage
context, but would for sure break if these functions were to be used
from e.g. a temp Main.

Cleaner and more future-proof. Also refactored slightly the code to make
it more readable.
And removed the 'experimental' warning in docs, this should have been
removed a long time ago.
The Keying Screen and the Anti-Aliasing nodes produce bad results in the
viewport compositor. This is because their cached resources are
allocated from the GPU texture pool, so they might get overwritten.
To fix this, we make sure those are not allocated from the texture pool.
It would both set the dome light color and export a texture with that
same color, which would double up. It was also using the World.exposure
member which is not used anywhere else in Blender.

Intersect mode needs to set everything **outside** of the selection mask
to non-selected and leave the rest untouched.
We already had the comment to "un-set all elements not in the mask" but
that was actually unsetting **everything**.
In theory, we could also early out for `SEL_OP_AND` since the following
`apply_mask_as_` calls are not doing anything for `SEL_OP_AND` really
(but left the change to be minimal).

In setups where only very few elements are processed at once, the lazy-threading
hints that come from `parallel_for` are not triggered. However, often it can
still be worth to use multi-threading in such cases. Therefore, we need to find
additional places where the lazy-threading hints are sent. There are many
possibilities and we probably have to add them step by step as we find .blend
files that show missing multi-threading.
In this patch I choose to send the hint at the beginning of evaluating a repeat
zone if it has 10 or more iterations. The exact number here is just a guess and
could be fine tuned over time if necessary.
A slightly modified version of the file in #134230 speeds up from ~1100ms to
~100ms with this change. The exact speedup changes quite a bit each run, but is
always between 5 and 20x, so it's quite noticable.
