This commit fixes T90633, it changes the behavior of the `Frame All`
operation when the user is tabbed into a metastrip: instead of using
the scene timeline's range, `Frame All` uses the current metastrip's
range.

When using downscaled preview size with proxies, transform effect
doesn't compensate for fact, that pixels are effectively larger. There
was compensation for scene render size already.
Use same compensation method as text effect uses for font size.
Commit e1665c3d31 added math to do 2D affine transformations with 3x3
matrices, but these matrices are also used for 3D transformations.
Remove added functions and use 4x4 matrices for 2D transformation.

Issue was caused by adding `seq->sound` check in ded68fb102 in
function `BKE_sound_scene_add_scene_sound` as `offset_time` field was
introduced to resolve sub-frame a/v misalignment.
Scene strips don't have `bSound` allocated but also don't suffer from
a/v misalignment.
Remove `seq->sound` check and don't apply any offset for scene strips.

Make the "xform" tool/gizmo available for strip transformations in the
sequencer preview window.
Because of the amount of hacks needed to make the gizmo work nicely with
multiple strips at the same time, it was decided to only show the
translate gizmo when multiple strips are selected.
This is because the transforms with multiple strips would appear buggy
because of our lack of shearing support in the transform system.
There is also currently no way to properly sync the gizmo drawing with
the transform when using multiple strips.

- Use 2D cursor in the preview space using shortcuts
matching the UV editor and 3D view.
- Add Cursor tool, cursor transform.
- Support for cursor and bound-box pivot.
- Add pivot pie menu.
`SequencesMeta.new_movie()` API function caused meta strip to change
length. Similar issue has been fixed in transform code by checking
if `MetaStack` exists. `MetaStack` is not used when changing data in
python.
Provide `seqbase` to `SEQ_time_update_sequence()` so the function can
check if change happens inside of meta strip.
This patch also merges `seq_time_update_sequence_bounds()` into
`SEQ_time_update_sequence()`. This is because same issue applies for
both functions and it is confusing to have more time update
functions.re if this will lead anywhere.

Previously we would only free animation strip data when doing final
renders. If not doing a final render or simply just playing back videos
in the VSE, we would not free decoders or non VSE cache data from the
strips.
This would lead to memory usage exploding in complex VSE scenes.
Now we instead use the dumb apporach of freeing everything that is not
currently visible.
Add Offset/Slope/Power controls to the color balance modifier. This is
already available in compositor.

on and off, a section in the theme settings to define the 9 possible colors and
two ways of changing the color tag through the UI. You can change the color
through the right-click context menu, or in the strip side panel next to the
strip name.
Color tags are defined in user preferences and they can be disabled in overlay

Draw thumbnails as strip overlay. This works for movie and image strips.
To draw thumbnails, this overlay has to be enabled and strips must be
tall enough.
The thumbnails are loaded from source file using separate thread and
stored in cache.
Drawing code uses only images stored in cache, and if any is missing,
background rendering job is started. If job can not render thumbnail,
to prevent endless loop of creating job for missing image it sets
`SEQ_FLAG_SKIP_THUMBNAILS` bit of `Sequence` flag.
To prevent visual glitches during timeline panning and zooming, `View2D`
flag `V2D_IS_NAVIGATING` is implemented. If bit is set, drawing code
will look for set of evenly distributed thumbnails that should be
guaranteed to exist and also set of previously displayed thumbnails.
Due to volatile nature of cache these thumbnails can be missing anyway,
in which case no new thumbnails will be drawn for particular strip.
Cache capacity is limited to 5000 thumbnails and performs cleanup of
non visible images when limit is reached.

Math implemented in 929d7597b3 was incorrect, but also inconsistent
with previous behavior.
`SEQ_SPEED_STRETCH` should change length only when right handle is
moved. This is now documented in code.
API function `move_to_meta` should move strips without changing context
data like `MetaStack` that tells UI which meta strip should be
displayed and operated upon.
`SEQ_time_update_sequence` relied on `MetaStack` to update meta strip
content length. Instead of changing function `SEQ_time_update_sequence`,
use function `SEQ_time_update_meta_strip_range` directly. This is
because caller would have to be aware of parent meta strip that needs
update anyway.
Add mode to overwrite strips on overlap instead of resolving overlap.
When overlap is created, 3 things can happen:
- On partial overlap, handles of overlapped strip are moved
- On complete overlap with smaller strip, overlapped strip is split
- On complete overlap with larger strip, overlapped strip is removed
This mode can be enabled in header.

We now use a for_each function with callback to iterate through all sequences in the scene.
This has the benefit that we now only loop over the sequences in the scene once.
Before we would loop over them twice and allocate memory to store temporary data.
The allocation of temporary data lead to unintentional memory leaks if the code used returns to exit out of the iteration loop.
The new for_each callback method doesn't allocate any temporary data and only iterates though all sequences once.

Simplify logic of speed effect frame calculation by using discrete math
where possible. Only `SEQ_SPEED_MULTIPLY` mode with animation requires
frame map to be built. Frame map building was simplified by removing
unused branches.
Functional change: Animating strip in negative range will reverse playback.
I assume this was limitation of previous system, where each frame map item
was limited to be within correct frame range. Now frame map can contain
values that point beyond usable range and they are limited by
`seq_speed_effect_target_frame_get`. This way it is possible to control
playback rate in both directions.
Mostly fixes T89120 apart from offset handling.

Prefetch needs to avoid rendering scene strips, because
- Rendering in background needs own dependency graph, which fails to
initialize from evaluated data.
- This locks UI and can make it unresponsive for long time periods.
In T88237 prefetch failed to avoid scene strip, because of effect strip
was attached to scene strip.
Ensure, that no effect that is attached to scene strip either directly
or indirectly would be rendered.

When splitting strips, first they are duplicated and then offsets
adjusted. This can fail on cross transitions, because some strips don't
overlap with split frame.
All strips, that relate to each other must be duplicated to ensure
correct relations after splitting, so solution is to delete non
overlapping strips from left or right side respectively.
Since cross transition don't have to overlap with source strips,
splitting such strips would lead to effect being deleted, which
could cause crash when iterating over strips in python. Therefore
splitting of such strips is now forbidden and will generate error.
Splitting of transition will also generate error solely because such
operation is illogical.

Caused by {rBbbb1936411a5}.
When adding strips via the new SEQ_add_XXX_strip functions, the
`Editing->seqbasep` pointer was passed around.
Following in `seq_add_generic_update` this `seqbasep` pointer was used
to ensure a unique name.
But `seqbasep` is the pointer to the current list of seq's being edited
(**which can be limited to the ones within a meta strip**).
We need unique names across all strips though (since these are used for
RNA paths, FCurves as reported), so now use the scene's `Editing-
>seqbase` (**which is the list of the top-most sequences**) instead.
Unfortunately this might have screwed files to a borked state, not sure
if this could easily be fixed...
