Doing so avoids having duplicated logic for working with pixel
data which is being passed throughout the render pipeline.
Notable changes:
- ImBug can now store GPU texture.
This is not very finished part of the API, which will be
worked further to support tiling for very-high-res images.
- Implicit sharing is removed from the image buffer, as it is
no longer needed.
There should be no functional changes on user level with this
change.

It was only used by OpenEXR and Iris images, and saving the Z Buffer
in those formats was disabled by default. This option comes from the
times prior to the addition of the Multilayer EXR.
It also worth noting that it was not possible to save Iris with Depth
pass from Blender as internally it is called IRIZ format and it was
not exposed. But even after exposing this format option something still
was missing as saving and loading ITIZ did not show up the Depth pass.
The reason of removal is to make it a more clear match of the ImBuf
with a render pass, and use it instead of a custom type in the render
result and render pass API. This will simplify the API and also avoid
stealing buffers and making shallow copies when showing the render
result.
For the cases when Depth is needed a Multilayer EXR is to be used,
as most likely more than just the Depth will be needed.
On a user level this change:
- Removes the "Z Buffer" option from the interface.
- It preserves existing sockets in compositor nodes, but it will
output black image. Also changing the image data-block will
remove the socket unless a Multilayer EXR with Depth pass image
is selected.
- Removes "Depth" socket of the Viewer and Composite nodes.

Before this change the ImBuf struct had dedicated fields for the
buffer data. Now the color space is stored inside of the struct
which wraps around the buffer information.
This only changes the field placement, without changing the way
it is handled. In the future one might imagine that operations
like stealing buffer data should null-ify the buffer colorspace
pointer. Such changes would need to have more accurate thinking
before implementation.
Should be no functional changes.

A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:

Allows to share buffer data between the render result and image buffers.
The storage of the passes and buffers in the render result have been
wrapped into utility structures, with functions to operate on them.
Currently only image buffers which are sharing buffers with the render
results are using the implicit sharing. This allows proper decoupling of
the image buffers from the lifetime of the underlying render result.
Fixes#107248: Compositor ACCESS VIOLATION when updating datablocks from handlers
Additionally, this lowers the memory usage of multi-layer EXR sequences
by avoiding having two copies of render passes in memory.
It is possible to use implicit sharing in more places, but needs
some API to ensure the render result is the only owner of data before
writing to its pixels.

The goal is to make it more explicit and centralized operation to
assign and steal buffer data, with proper ownership tracking.
The buffers and ownership flags are wrapped into their dedicated
structures now.
There should be no functional changes currently, it is a preparation
for allowing implicit sharing of the ImBuf buffers. Additionally, in
the future it is possible to more buffer-specific information (such
as color space) next to the buffer data itself. It is also possible
to clean up the allocation flags (IB_rect, ...) to give them more
clear naming and not have stored in the ImBuf->flags as they are only
needed for allocation.
The most dangerous part of this change is the change of byte buffer
data from `int*` to `uint8_t*`. In a lot of cases the byte buffer was
cast to `uchar*`, so those casts are now gone. But some code is
operating on `int*` so now there are casts in there. In practice this
should be fine, since we only support 64bit platforms, so allocations
are aligned. The real things to watch out for here is the fact that
allocation and offsetting from the byte buffer now need an explicit 4
channel multiplier.
Once everything is C++ it will be possible to simplify public
functions even further.

This patch contains changes needed for retiming sound strips.
`BKE_sound_set_scene_sound_pitch()` is replaced by
`BKE_sound_set_scene_sound_pitch_constant_range()` which uses new
Audaspace interface to set pitch in bulk.
This is done in `SEQ_retiming_sound_animation_data_set()` where retimed
sections are created for each strip. When strip is inside of meta
strip(s), the retimed sections of meta and actual strip are split where
they intersect and pitch is multiplied where they overlap. Each section
will have pitch value that is provided to audaspace.
Waveform overlay now represents retimed audio accurately.

When subsampling was introduced in VSE it was disabled during
editing. Only when rendering it was enabled. This lead to
cache being different between editing and rendering. Leading
to confusion.
This PR will enabled the subsampling when editing. This way
it is more consistent.

Image Transform use linear or nearest sampling during editing and exporting.
This gets sampling is fine for images that aren't scaled. When sequencing
however you mostly want use some sort of scaling, that leads to poorer
quality.
This change will use sub-sampling to improve the quality. This is only
enabled when rendering. During editing the subsampling is disabled to
keep the user interface reacting as expected.
Another improvement is that image transform is stopped at the moment
it hadn't sampled at least 4 samples for a scan line. In that case we
expect that there are no further samples that would change to result.
In a future patch this could be replaced by a ray/bounding bo intersection
as that would remove some unneeded loops in both the single sampled and
sub sampled approach.
UI panel may suggest, that disabling "Proxy & timecode" would cause
timecodes not being used, but this was not the case. Now timecodes will
be used only if the checkbox is checked.
These functions are almost identical, the main difference being
BLI_join_dirfile didn't trim existing slashes when joining paths
however this isn't an important difference that warrants a separate
function.
Add function `SEQ_time_content_end_frame_get` to get content end frame.
New function is shorthand for
`SEQ_time_start_frame_get() + SEQ_time_strip_length_get()`.
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`.
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.
