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.

- Remove Full Render size from VSE preview size. Use just 100% instead.
- Add Use Proxies checkbox to control whether proxies are used globally
- Move preview size to top so it is most prominent
- Set default to 100% preview size and use proxies

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.
Fixed in this patch.

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.

This argument was used to prevent infinite loop in lookups between disk

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.
This change should follow rBf448ff2afe7a77, but I have wrongly assumed,
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).

Logic was broken into finding gaps and ofsetting strips.
Functions were modified so they work on explicitly defined seqbase,
so they can be used as python API functions.
Functional changes:
- Improve performance by calculating gap length and offseting strips
at once. Previously strips were offset by one frame.
- Calculate gap from start frame. Previously gap was considered only
inbetween strips.

Move most functions into separate files.
File sequencer.c is reserved for alloc, free and duplicating functions.
There should be no functional changes.
Proxies are expected to be fast to read. Storing them in cache has
little to no effect on performance.
This change also allows to omit invalidation of cache when user switch
between proxies and original media.
