Patch implements better way to control playback speed than it is
possible to do with speed effect. Speed factor property can be set in
Time panel.
There are 2 layers of control:
Option to retime movie to match scene FPS rate.
Custom speed factor to control playback rate.
Since playback rate is strip property, it is now possible to manipulate
strip as normal one even if it is retimed.
To facilitate manipulation, some functions need to consider speed factor
and apply necessary corrections to strip offset or strip start. These
corrections may need to be float numbers, so start and offsets must be
float as well.
Sound strips now use speed factor instead of pitch. This means, that
strips will change length to match usable length. In addition, it is
possible to group movie and sound strip and change speed of meta strip.

This patch makes it possible to manipulate strips without need to use
update functions to recalculate effect and meta strips.
Prior to this change function `SEQ_time_update_sequence` had to be used
to update mainly effects and meta strips. This was implemented in a way
that relied on sorted list of strips, which can't always be done and in
rare cases this approach failed.
In case of meta strips, `seqbase` had to be passed and compared with
"active" one to determine whether meta strip should be updated or not.
This is especially weak system that is prone to bugs when functions are
used by python API functions.
Finally, other strip types had startdisp` and `enddisp` fields updated
by this function and a lot of code relied on these fields even if strip
start, length and offsets are available. This is completely
unnecessary.
Implemented changes:
All effects and meta strips are updated when strip handles are moved or
strip is translated, without need to call any update function.
Function `SEQ_time_update_sequence` has been split to
`SEQ_time_update_meta_strip_range` and
`seq_time_update_effects_strip_range`. These functions should be only
used within sequencer module code. Meta update is used for versioning,
which is only reason for it not being declared internally.
Sequence fields `startdisp` and `enddisp` are now only used for
effects to store strip start and end points. These fields should be
used only internally within sequencer module code.
Use function `SEQ_time_*_handle_frame_get` to get strip start and end
points.
To update effects and meta strips with reasonable performance, cache
for "parent" meta strip and attached effects is added to
`SequenceLookup` cache, so it shares invalidation mechanisms.
All caches are populated during single iteration.
There should be no functional changes.

To clarify term still frame: This is portion of strip that displays
static image. This area can exist before or after strip movie content.
Still frames were implemented as strip property, but this was never
displayed in panel. Only way to set still frames was to drag strip
handle with mouse or using python API. This would set either
`seq->*still` or `seq->*ofs` where * stands for `start` or `end`.
When strip had offset, it can't have still frames and vice versa, but
this had to be enforced in RNA functions and everywhere in code where
these fields are set directly. Strip can not have negative offset or
negative number of still frames.
This is not very practical approach and still frames can be simply
implemented as applying negative offset. Merging these offsets would
simplify offset calculations for example in D14962 and could make it
easier to also deprecate usage `seq->*disp` and necessity to call
update functions to recalculate strip boundaries.
For users only functional change is ability to set negative strip offset
using property in side panel.

Issue was caused by treating such strip as meta and using
`seq->channels` directly, which is not valid for scene strips.
Pointer to channels is now provided by function
`SEQ_get_seqbase_from_sequence`.

When handles are moved, job is created only for strips that need to

This patch adds channel region to VSE timeline area for drawing channel
headers. It is synchronizedwith timeline region. 3 basic features are
implemented - channel visibility, locking and name.
Channel data is stored in `SeqTimelineChannel` which can be top-level
owned by `Editing`, or it is owned by meta strip to support nesting.
Strip properties are completely independent and channel properties are
applied on top of particular strip property, thus overriding it.
Implementation is separate from channel regions in other editors. This
is mainly because style and topology is quite different in VSE. But
also code seems to be much more readable this way.
Currently channels use functions similar to VSE timeline to draw
background to provide illusion of transparency, but only for background
and sfra/efra regions.
Great portion of this patch is change from using strip visibility and
lock status to include channel state - this is facilitated by functions
`SEQ_transform_is_locked` and `SEQ_render_is_muted`
Originally this included changes in D14263, but patch was split for
easier review.

So far it was needed to declare a new RNA struct to `RNA_access.h` manually.
Since 9b298cf3dbec we generate a `RNA_prototypes.h` for RNA property
declarations. Now this also includes the RNA struct declarations, so they don't
have to be added manually anymore.

`IMB_transform` is used in VSE. It had a required crop parameter
for cropping the source buffer. This is not always needed.
In the image engine we want to use the use the `IMB_transform`

When scaling down image, users expect to see background, which doesn't
currently happen in VSE. This is because strips use cross blend mode by
default, because alpha over is much slower. Reason is, because any area
of image can be transparent, and therefore it can't have early out
implemented in a way that cross blend mode can.
Flag images rendered by codecs that don't support transparency as fully
opaque and implement a form of early out for alpha over blend mode.
When rendering image stack, 2-input effects are ignored on the
"way down". Alpha over needs rendered overlay image to decide whether it
will use only overlay or background too. Therefore overlay can be
rendered safely before it is used. Image flags can be checked and it can
be freed if needed. Freeing doesn't cause any performance degradation,
because image is always stored in cache.
This feature does not improve blend mode performance. In summary, it
only allowes for having alpha over blend mode on background images
without suffering from lower performance.

When proxy size lower than 100% is used, clip strips are rendered with
incorrect image size.
This is because if proxies aren't enabled in movieclip, it automatically
falls back on rendering original media. Sequencer doesn't have knowledge
about this and since 9c99292a16df it assumes that image is proxy,
because it explicitly requested this size.
Check movieclip flag to see if proxies are enabled.

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.

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.

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.

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
in VSE.

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.

This bug was introduced in 0b7744f4da66. 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

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.
