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.
Skip updating normals & tessellation for contiguous geometry regions
for operations such as translate & uniform scale.
This means when all geometry is selected, no updates are needed
as the relative locations of vertices aren't being modified.
Performance:
As this is skipping a multi-threaded operation,
larger improvements are noticeable on systems with fewer cores.
- ~1.15x to ~1.3x overall gain for 32 cores.
- ~1.7x to ~2.2x overall gain for 1 core (limited using `-t 1` argument).
Details:
- Rotate & non-uniform scale only skip tessellation.
- Proportional editing and axis-mirror have special handling
ensure geometry is properly grouped before considering
a face part of a single group that can be skipped.
- Loose vertices always need their normals to be recalculated
since they're calculated based on the location.
- Non-affine transform operations such as shrink-fatten & bend,
don't take advantage of this optimization.
- Snap projection also disables the optimization.
`t->values` does not necessarily represent a final value of the
transformation, as each mode treats this value differently.
So, unfortunately, we cannot have a generic offset solution for modal
transform operations. Offset needs to be handled by each mode.
Note: Currently only, `Move`, `Rotate` and `Resize` support this.
* Mark either all or no class methods with override
* Don't use zero sized array since it has a different size in C and C++.
Using a little more memory here is not significant.
* Don't use deprecated mechanism to mark private GSet members in clang
just like we don't for MSVC, it warns even for simple zero initialization.
This fixes T88346.
The code is also more readable by making a better distinction between
the texts used for Distances, "Proportional Size" and "AutoIK-Len".
And the text used to translate the "Proportional Size" is reused.
This patch fixes many minor spelling mistakes, all in comments or
console output. Mostly contractions like can't, won't, don't, its/it's,
etc.

Reduce complexity of sequencer transform code by removing recursivity.
This is possible by treating meta strips (mostly) as any other strip and
containing all transform code within SEQ_ functions.
Unfortunately internally meta strips still require special treatment,
but all complexity from code all over transform code seems to be
possible to contain within one function.
Functional change:
Previously adjusting handle of single image strip moved animation.
Now animation is not moved, which is behavior for all other strips.

Starts scrolling when dragging a node or node link and going outside the current window.
Largely copied from the VIEW2D_OT_edge_pan operator.
Edge panning operator customdata and supporting functions now in
UI_view2d.h, so they could be used by operators in other editor
libraries. The VIEW2D_OT_edge_pan operator also uses this customdata and
shared functions now. Operators properties can be used to configure
edge panning margins and speed for each use case, rather than using
hardcoded values.
The speed function for edge panning has been tweaked somewhat:
* "Speed per pixel" has been replaced with a "speed ramp" distance.
This is more intuitive and also creates an upper bound for the speed,
which can otherwise become extreme with large cursor distance.
* "Max speed" is reached at the end of the speed ramp.
* Padding the region inside and outside is applied as before, but both
values are operator properties now.
Node transform operator also supports edge panning. This requires
an offset for changes in the view2d rect, otherwise nodes are "stuck"
to the original view.
Transform operator had cursor wrapping categorically enabled, but this
gets quite confusing with the edge scrolling mechanism. A new TransInfo
option T_NO_CURSOR_WRAP has been introduced to disable this behavior.
The double negative is a bit annoying, but want to avoid affecting the
existing transform modes, so by default it should still set the
OP_IS_MODAL_GRAB_CURSOR flag (which then sets the WM_CURSOR_WRAP_XY
flag during modal execution).

Support calculating face normals when tessellating. When this is done
before updating vertex normals it gives ~20% performance improvement.
Now vertex normal calculation only needs to perform a single pass on the
mesh vertices when called after tessellation.
Extended versions of normal & looptri update functions have been added:
- BM_mesh_calc_tessellation_ex
- BM_mesh_normals_update_ex
Most callers don't need to be aware of this detail by using:
- BKE_editmesh_looptri_and_normals_calc
- BKE_editmesh_looptri_and_normals_calc_with_partial
- EDBM_update also takes advantage of this,
where calling EDBM_update with calc_looptri & calc_normals
enabled uses the faster normal updating logic.
This field was used for extend feature to get handle position of
metastrip children. Since D9972 extend feature works only on meta
strip itself, not it's children.
So `SEQ_transform_get_left_handle_frame()` second argument is always
false and can be removed.
Another instance of `seq->tmp usage` is hack to distinguish strips to be
shuffled, which is not covered by this patch.

This patch exposes functionality for performing partial mesh updates
for normal calculation and face tessellation while transforming a mesh.
The partial update data only needs to be generated once,
afterwards the cached connectivity information can be reused
(with the exception of changing proportional editing radius).
Currently this is only used for transform, in the future it could be
used for other operators as well as the transform panel.
The best-case overall speedup while transforming geometry is about
1.45x since the time to update a small number of normals and faces is
negligible.
For an additional speedup partial face tessellation is multi-threaded,
this gives ~15x speedup on my system (timing tessellation alone).
Exact results depend on the number of CPU cores available.

Event though in practice this wasn't causing problems as the fixed size
buffers are generally large enough not to truncate text.
Using the result from `snprint` or `BLI_snprintf` to step over a fixed
size buffer allows for buffer overruns as the returned value is the size
needed to copy the entire string, not the number of bytes copied.
Building strings using this convention with multiple calls:
ofs += BLI_snprintf(str + ofs, str_len_max - ofs);
.. caused the size argument to become negative,
wrapping it to a large value when cast to the unsigned argument.
This fallback is an old hack.
It is difficult to have an orientation convention when several random
factors determine which one should be used.
In this case, to "fix" the problem, a new behavior had to be implemented.
Now the redo when moving the camera in `Camera View` has the default
orientation as `View`.
When activated in modal, `translate`, `resize`, `rotate`, `shear` and
`edge_rotate_normal` use a different orientation than the set in scene.
This orientation needed to match since some of these modes can be switched
during operation.
The default orientation for these modes was `V3D_ORIENT_VIEW`.
And this changed when finishing the `translate` and `resize` to
`V3D_ORIENT_GLOBAL`.
But this could cause inconsistencies when inputting values from the
keyboard.
The solution now is to change the orientation when you change the mode.
---
Note: Although the user can expect the value entered to reflect the
orientation set in the scene, it would require a lot of changes and would
not be really useful.
Recently `SEQ_sort()` function was split so functionality is provided
on per-seqbase basis. After discussion about this split, it turned out,
that per-seqbase operation is only that should be provided, because
RNA API functions need to be able to access arbitrary seqbase

`SEQ_sort` function to operate on seqbase.
