When adding texts or various simple effects I often copy-paste strips
to reuse properties from a template such as font or position. I assume
this is common workflow. Issue with this workflow is, that active strip
is not changed after pasting, so when adjusting property, it is original
strip that is being modified.
This is not issue when duplicating strips - selection state is
transfered to duplicate strips, such that duplicate of active strip is
set to be active and duplicate of selected strip is set to selected.
Implement same selection transfering behavior in paste operator, that
exists in duplicate operator.
Since strip can be deleted after copying, it is not possible to rely
on sequencer state. This is true even when pasting strips to different
scene. Therefore active strip name must be stored in clipboard.

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

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.

Inside the sequencer the cropping and transform of images/buffers were
implemented locally. This reduced the optimizations that a compiler
could do and added confusing code styles. This patch adds
`IMB_transform` to reduce the confusion and increases compiler
optimizations as more code can be inlined and we can keep track of
indices inside the inner loop.
This increases end-user performance by 30% when playing back aa video

Use SEQ_time_strip_intersects_frame function to test if strip intersects with frame.
Note: There are cases where this function should not be used. For example splitting
strips require at least 1 frame "inside" strip. Another example is drawing, where
playhead technically doesn't intersect strip, but it is rendered, because current
frame has "duration" or "thickness" of 1 frame.

When sound strip is above another strip such as movie strip, it prevents

This bug was introduced in 0b7744f4da. Function `must_render_strip()`
checks if there is any strip with `SEQ_BLEND_REPLACE` blending and
considers this strip as lowest strip in stack. Sound strips do have this
blend mode set, which caused the bug.

checking with `must_render_strip()` function

Due to misunderstanding of how strip duplication works, animation data
was duplicated on all strips when any strip was split.
`SEQ_sequence_base_dupli_recursive()` duplicated data on strip that was
being split, and `SEQ_ensure_unique_name()` duplicated animation on all
strips.
Only duplication should be done with `SEQ_ensure_unique_name()` and only
on right side split strips, because only these strips are duplicated.
Fix issue described in T87678, which was partially a bug and partially
change in intended(at least as far as I can tell) behaior.
Function `evaluate_seq_frame_gen` that was partially responsible for
filtering strips in stack for rendering wasn't working correctly.
Intended functionality seems to be removing all effect inputs from stack
as it is unlikely that user would want these to be blended in. However
there was logic to exclude effects placed into same input, which because
of weak implementation caused, that any effect input, that is effect as
well will be considered to be part of stack to be blended in.
This bug was apparently used to produce effects like glow over original
image.
Even though this is originally unintended, I have kept this logic, but
I have made it explicit.
Another change is request made in T87678 to make it possible to keep
effect inputs as part of stack when they are placed above the effect,
which would imply that blending is intended. This change is again
explicitly defined.
Whole implementation has been refactored, so logic is consolidated
and code should be as explicit as possible and more readable.
`must_render_strip function` may be still quite hard to read, not sure
if I can make it nicer.
Last change is for remove gaps feature code - it used same rendering
code, which may be reason why its logic was split in first place.
Now it uses sequencer iterator, which will definitely be faster than
original code, but I could have used `LISTBASE_FOREACH` in this case.

Splitting of effect strip alone wasn't handled properly. Previously
this resulted in duplicating effect strip, and it was broken at least
from 2.79.
Change in rB8ec6b34b8eb2 was intended to allow splitting strips
individually, so it can be used as RNA API function but also so it
requires as little glue logic as possible.
This is fixed by splitting all dependent strips at once in 2 separate
ListBases for left and right strips. Strips can be finally moved into
original `ListBase`.
With this fix it is still possible to split strips individually with
little glue logic. RNA API function could return list of split strips
as well, currently at least one strip in chain will be provided so
chain can be reconstructed on python side.
