Practice shows that when combining actions and direct animation
it is usually best to combine location, rotation and scale
separately, which is implemented by the Split Channels modes
recently introduced in D9469 for Copy Transforms. This completes
the same set of 6 choices for the Action Constraint.
The default for new constraints is changed to the newly
added Before Original (Split Channels) mode.
The original patch is motivated by Loic Pinsard, who created
an addon that does the equivalent of this feature by splitting
the action into two, separating location and rotation+scale.

This makes the internal naming consistent with the public API. And also gives
us a visibility_flag rather than restrictflag that can be extended with more
flags.

only still frames.
Fix effect strips of transformed strips causing snapping to prevoius

Abbreviations are harder to read and understand thus it is best to be direct.
For example without understanding and context it is hard to know exactly what "Len" means.
Function signatures for snap callbacks used `const` incorrectly
which was hidden by casting function types.
This made it seem as if the input arguments wouldn't be change and
wouldn't be initialized.
Name return arguments with an `r_` prefix, order them last,
remove function casts and correct `const` usage.
Constraining to X axis caused snapping to not work at all. Constraining
to Y axis caused snapping indicator to be drawn, when snapping doesn't
occur.

During a mesh transformation in edit mode (Move, Rotate...), only part of
the batch cache needs to be updated.
This commit allows only update only the drawn batches seen in
`BKE_object_data_eval_batch_cache_deform_tag` if the new
`ID_RECALC_GEOMETRY_DEFORM` flag is used.
This new flag is used in the transforms operation for edit-mesh and
results in 1.6x overall speedup in heavy subdiv cube.

Confusingly, BKE_scene_frame_get did not match the frame number as expected by
BKE_scene_frame_set. Instead it return the value after time remapping, which
is commonly named "ctime".
* Rename BKE_scene_frame_get to BKE_scene_ctime_get
* Add a new BKE_scene_frame_get that matches BKE_scene_frame_set
* Use int/float depending if fractional frame is expected
This constraint can be naturally viewed as a prototype for a future
4x4 matrix math node (or subset thereof), since its basic semantics
already is matrix assignment. Thus it makes sense to add math options
to this constraint to increase flexibility in the meantime.
This patch adds support for several operations that would be useful:
- An option to remove shear in the incoming target matrix.
Shear is known to cause issues for various mathematical operations,
so an option to remove it at key points is useful.
Constraints based on Euler like Copy Rotation and Limit Rotation
already have always enabled shear removal built in, because their
math doesn't work correctly with shear.
In the future node system shear removal would be a separate node
(and currently Limit Rotation can be used as a Remove Shear constraint).
However removing shear from the result of the target space conversion
before mixing (similar to Copy Rotation) has to be built into
Copy Transforms itself as an option.
- More ways to combine the target and owner matrices.
Similar to multiple Inherit Scale modes for parenting, there are
multiple ways one may want to combine matrices based on context.
This implements 3 variants for each of the Before/After modes
(one of them already existing).
- Full implements regular matrix multiplication as the most basic
option. The downside is the risk of creating shear.
- Aligned emulates the 'anti-shear' Aligned Inherit Scale mode,
and basically uses Full for location, and Split for rotation/scale.
(This choice already existed.)
- Split Channels combines location, rotation and scale separately.
Looking at D7547 there is demand for Split Channels in some cases,
so I think it makes sense to include it in Copy Transforms too, so that
the Mix menu items can be identical for it and the Action constraint.

Address initial feedback:
- Use checkboxes instead of radio buttons
- Hide snapping distance control from UI
- Tweak snapping line color - use selected strip color, 50% transparency. Similar to other editors
- Draw 2px thick line, since strip outline is also 2px thick

Edit-mesh partial update logic assumed translate didn't need normals
to be recalculated (for faces with all vertices being transformed).
However translate can optionally rotate which requires
all transformed normals to be updated.
Check for this case and use the previous partial-update method
when it modified extra geometry, so the normals are properly reset.
Further updates need not recalculate them.
Supporting both object & edit-mode is more involved.
Both cases are now supported with object mode tracking the last-used
state for rotation so it's only reset once when rotation is disabled.
Multi-threading support for transform modes: bevel-weight, crease,
push-pull, rotate, shear, shrink-fatten, skin-resize, to-sphere,
trackball & translate.
This is done using a parallel loop over transform data.
From testing a 1.5million polygon mesh on a 32 core system
the overall performance gains were between ~20-28%
To ensure the code is thread-safe arguments to shared data are const.

Reserve the term count for values that require calculation
(typically linked lists).
Without this convention it's difficult to know if using a length
accessor function in a loop will be O(N^2) without inspecting the
underlying implementation.
Change snapping behavior to snap strip edges when they are close to snap point.
Default behavior is, that each transformed strip is snapped to any other strip.
Implement snapping controls in sequencer tool settings. These controls include:
- Snapping on/off
- Ability to snap to playhead and strip hold offset points
- Filter snap points by excluding sound or muted strips
- Control snapping distance
Snapping controls are placed in timeline header similar to 3D viewport

Use const arguments to simplify further optimizations.
Transforming elements shouldn't need to change their containers
data-structures.
ElementResize for grease pencil stroke thickness was
modifying TransInfo.num & TransInfo.values_final.
Now copies are operated on to preserve const correctness although
it's worth investigating if this can be avoided altogether.
