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.

The matrix in itself is always linear so it could be replaced by two additions.

Fixed the logic for seeking in ffmpeg video files.
The main fix is that we now apply a small offset in ffmpeg_get_seek_pos
to make sure we don't get the frame in front of the seek position when
seeking backward.
The rest of the changes is general cleanup and untangling code.

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
from rendering movie strip.
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.
Remove all sound strips and muted strips from stack collection before
checking with `must_render_strip()` function
Since version 2.80, the annotations of the Scene strip were not displayed in VSE. Also, the UI panel was`Grease Pencil` and must be `Annotation`
The problem was the offscreen render hasn't evil_CTX and the section of the annotation was never called.

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.

When frame is rendered to file, bilinear interpolation on scaled images
caused blurred edges.
This is fixed by not doing interpolation with pixels outside of source
buffer.
Such fix doesn't cover cropped images which are currently cropped by
filling area of image with black transparent color, because image buffer
has bigger size than visible image area.
This is fixed by offsetting range used in previous fix by amount, that
would correspond to crop distance. Because of this, image area doesn't
even need to be filled with transparency.

`SequenceElement` type `orig_height` and `orig_width` members were
set to incorrect size when using proxies and not set when strip was
added which caused value to be unset.
Since now image dimensions must be read when strip is created,
these members can be initialized. When proxies are used, do not set
original size since it is not guaranteed, that proxies are exact size.
These values are not guaranteed to be up to date or exact. They should
be used for strictly informative purposes.

Isolate RNA and operator logic from functions that create strips.
- Operator specific code was removed from `SeqLoadInfo` structure and
`SEQ_add_*` functions.
- Strip loading code was removed from RNA and operator functions.
- `SEQ_add_*` API was unified to work on `SeqLoadData` struct.
Only exception is image strip, which require files to be loaded
separately to strip creation itself. This is not ideal, but I think
it's acceptable.
- Some functions and variables were refactored so the code reads
better.
There are minor functional changes (coincidental bugfixes):
- Operator errors are reported per-strip. Previously they were not
reported at all?
- `new_sound()` RNA API function now create sound with length of 1
if source file does not exist. Previously it created strip with
length of 0.
- Replace selection operator property wasn't working correctly.

This bug happens when media size doesn't match scene size and proxies
are enabled. This is because some strips are rendered in preview size
already - effects, mask or strips using proxies.
If strip input is prescaled it needs to be known when transforming
images, which does also scaling to preview size as one operation.
whether image needs prescaling is defined in function
`seq_need_scale_to_render_size()`
Problem was introduced in 5713626422. Previously all images were
scaled to fit into preview, and this was considered as baseline for
further image transformation.

Previously raw images were not cached if image wasn't preprocessed.
This caused issue, that image had to be read from disk on every redraw.
Effect strips must be excluded, because this would cause problem with
invalidation. Effect strips can use preprocessing however. This is
mainly to allow usimg modifiers on them.

that it has been implemented already.

This value was meant to be used for keeping images that are slowest to
render in cache. Method of measurement was flawed, because it doesn't
take UI overhead into consideration.
Cache panel is to be removed because users should not have to tweak
settings like this. It is not useful for development either, therefore
it is removed completely.
This commit resolves problem introduced in e1665c3d31 - it was
difficult to import media at their original resolution.
This is done by using original resolution as reference for scale.
All crop and strip transform values and their animation is converted
form old files.
To make both workflows easy to use, sequencer tool settings have been
created with preset for preffered scaling method. This setting is in
sequencer timeline header and add image or movie strip operator
properties.
Two new operators have been added:
`sequencer.strip_transform_fit` operator with 3 options: Scale To Fit,
Scale to Fill and Stretch To Fill.
Operator can fail if strip image or video is not loaded currently, this
case should be either sanitized or data loaded on demand.
`sequencer.strip_transform_clear` operator with 4 options:
Clear position, scale, rotation and all (previous 3 options combined).
