5a2a6da0a2 VSE: Blade Tool Cursor
This patch adds initial cursor support for the blade tool, with bitmaps
for 16x16, 24x24, and 32x32 cursors.

Additional Changes:
- Locked strips now show a "stop" icon when hovered over.
- Previously, the frame to split was truncated when clicking in between frames.
  Now, round to the closest frame.
- Previously, the blade operator was able to select padded strip handles
  outside of strip bounds. This bug has been resolved, so that selection with
  the blade tool can only happen via box-select passthrough.

fe1e866fb9 VSE: Slip Operator 2.0
This patch completely reworks the slip operator from the ground up,
reorganizing code to be simpler and adding more clarifying documentation.

Major Changes:
- Add modal keymap to the operator along with an interactive status bar.
- Show offset overlays to the left and right of strips whenever slipping.
- Add option to "clamp" slipped strips.
- Rework input to be accumulative, avoiding "jumps" when transitioning in/out
  of precision mode.

Fixes:
- Properly draw header when initializing operator before any events have been
  sent, and reorganize event flow so that all events have an immediate effect.
- Properly clamp subframe slips.

It seems to think signed integers might lead to this kind of overflow,
but it's unclear why these two cases are causing warnings specifically.

144b1a7d56 Fix: VSE crash when moving retiming key
Caused by not checking against key array size. The issue was introduced
in ee9e4ead8d. It looks like mistake done during refactoring, because
the code was supposed to fix previous transition segment, not only the
next one.

The previously code attempted to reduce levels of indentation, but it
was less readable and error prone. Now it should be more obvious what
the intent is.

0b633fab3e Fix #135631: Locked strip visibility can't be changed
Strip locking was meant to be used with strip transformation only. So
the check, whether strip is locked is removed from hide/unhide operator.

Further it was requested to lock sound strip subframe offset. Since this
is time related property, it was moved to time panel. This also
addresses request to make it more obvious, why the value can't be
changed.
The name of the property was clarified from "Offset" to
"Sound offset", because there are another 2 offsets in the panel.

Finally, when channel is locked, properties in side panel now reflects
this state. This is done by adding RNA get function for `Strip.lock`
property. Function `seq::transform_is_locked` is used instead of
checking `SEQ_LOCK` flag, because it also checks channel state. With
this setup, the lock property can't be disabled while channel is locked.
However strip lock flag will be unset, which can be prevented. (I am not sure which is better. Both are fine in my eyes.)

3e023fcf79 VSE: Slip keyframes with strip content
The "slip strip contents" operator in the VSE now can move the strip
keyframes. There is a property to enable keyframe slipping.
The property is disabled by default, mainly because animation is
often used for fade in/out, which would be annoying if it moved with
content.

60de2103c0 Fix: Crash when adding strips above channel 128
Crashes were caused by setting `Strip::machine` above `MAX_CHANNELS`
value.

Instead of clamping this value at multiple places, setter function
`seq::strip_channel_set` was added that implements clamping.

This also allows for better handling of clamping if it was ever needed.

Function `strip_transform_handle_expand_to_fit` still sets machine value
directly and above `MAX_CHANNELS` as a hack. This could be avoided, but
it would require some refactoring.

1d76cbab64 Cleanup: sequencer: Replace 'void' MEM_[cm]allocN with templated, type-safe MEM_[cm]allocN<T>.
The main issue of 'type-less' standard C allocations is that there is no check on
allocated type possible.

This is a serious source of annoyance (and crashes) when making some
low-level structs non-trivial, as tracking down all usages of these
structs in higher-level other structs and their allocation is... really
painful.

MEM_[cm]allocN<T> templates on the other hand do check that the
given type is trivial, at build time (static assert), which makes such issue...
trivial to catch.

NOTE: New code should strive to use MEM_new (i.e. allocation and
construction) as much as possible, even for trivial PoD types.

dd168a35c5 Refactor: Replace MEM_cnew with a type-aware template version of MEM_callocN.
The general idea is to keep the 'old', C-style MEM_callocN signature, and slowly
replace most of its usages with the new, C++-style type-safer template version.

* `MEM_cnew<T>` allocation version is renamed to `MEM_callocN<T>`.
* `MEM_cnew_array<T>` allocation version is renamed to `MEM_calloc_arrayN<T>`.
* `MEM_cnew<T>` duplicate version is renamed to `MEM_dupallocN<T>`.

Similar templates type-safe version of `MEM_mallocN` will be added soon
as well.

Following discussions in !134452.

NOTE: For now static type checking in `MEM_callocN` and related are slightly
different for Windows MSVC. This compiler seems to consider structs using the
`DNA_DEFINE_CXX_METHODS` macro as non-trivial (likely because their default
copy constructors are deleted). So using checks on trivially
constructible/destructible instead on this compiler/system.

148aa54398 ImBuf: unify color space transform threaded/non-threaded functions
There's no point in having non-threaded image color space conversion functions.
So merge the threaded and non-threaded functions and clarify names while at it:

- IMB_colormanagement_transform & IMB_colormanagement_transform_threaded
    -> IMB_colormanagement_transform_float
- IMB_colormanagement_transform_byte & IMB_colormanagement_transform_byte_threaded
    -> IMB_colormanagement_transform_byte
- IMB_colormanagement_transform_from_byte & IMB_colormanagement_transform_from_byte_threaded
    -> IMB_colormanagement_transform_byte_to_float

These places were doing single-threaded colorspace conversion previously, and
thus now are potentially faster:
- IMB_rect_from_float (used in many places)
- EXR image "save as render" saving (image_exr_from_scene_linear_to_output)
- Object baking (write_internal_bake_pixels, write_external_bake_pixels)
- General image saving, clipboard copy, movie preparation
  (IMB_colormanagement_imbuf_for_write)
- Linear conversion when reading HDR images/movies
  (colormanage_imbuf_make_linear)
- EXR multi-layer conversion (render_result_new_from_exr)

For one case I benchmarked, which is to render out a 2D stabilized 10 bit input
movie clip out of VSE, the total render time went from 49sec down to 44sec
(Ryzen 5950X), one of the single-threaded parts was the colorspace conversion
in the movieclip code.

89f61ee6cb Fix: Use Font Flag to Identify Default Fonts
with #133413 the intent was that VSE Text strips would not use the
fallback font stack if using a custom (non-default) font. However this
determination was done by comparing the font id. This was very weak as
the id can vary quite a bit within the first few fonts. This PR instead
adds a BLF function (BLF_is_builtin) that uses BLF_DEFAULT font flag
instead.

4e02acf2ba Fix #134607: Sequencer render animation preview not working
This main thread check was introduced in 4536a4c610. At the time OpenGL
only ever worked in the main thread, but that limitation was lifted in
Blender 2.80.

With this operator being converted to use the jobs system, it now needs
to work in non-main threads. Note that this code does not run in parallel
with main thread drawing anyway, because of WM_job_main_thread_lock_acquire
and draw manager locks. What changed is that we can now activate OpenGL
contexts on other threads.

2a44bdfbd0 Refactor: Use C++ types for vectors strip image transform code
All 2D vectors related to image transform code were changed to float2.
Previously, it was decided, that 4x4 matrix should be used for 2D
affine transform, but this is changed to 3x3 now.

Texture painting code did rely on `IMB_transform` with 4x4 matrix.
To avoid large changes, I have added function
`BLI_rctf_transform_calc_m3_pivot_min`.

Main motivation is cleaner code - ease of use of c++ API, and avoiding
returning values by arguments.

b2660dbd2b Fix: Improve retiming speed get/set code precision
Use float for intermediate values when calculating speed or timeline
frames.

More details on precision improvement itself: In some cases, setting
strip speed to say 70% would result in actual speed being set to say
69.5%. With this change, the number would be closer or equal to 70%.

There few tangentially related changes:
- `SEQ_retiming_key_speed_get` was changed so both functions work in
  same time domain.
- `SEQ_retiming_key_speed_set` now expects speed as float factor
  instead of percentage. This is consistent with get function return
   value.
- Improve variable names, for better code readability.

b9f253564e VSE: Python API: Deprecate sequence properties and replace with new ones

The old prooperties are still there and fully functional, but the description is changed
to indicate that these will be removed in the future and that the new properties should
be used instead.

| Deprecated property | Replacement property |
| --------------------------------- | ----------------------------------- |
| `context.active_sequence_strip` | `context.active_strip` |
| `context.selected_editable_sequences` | `context.selected_editable_strips` |
| `context.selected_sequences` | `context.selected_strips` |
| `context.sequences` | `context.strips` |
| `SequenceEditor.sequences` | `SequenceEditor.strips` |
| `SequenceEditor.sequences_all` |  `SequenceEditor.strips_all` |
| `MetaStrip.sequences` | `MetaStrip.strips` |

Previously, rna paths for animation data on strips started with `sequence_editor.sequences`.
This PRadds versioning for the rna paths to make sure to use
the new naming scheme. This does mean that in previous versions of blender,
the animations don't show but the data is not lost (even if the file is saved in the older version).

Also do some cleanup of existing python scripts inside the source to use the
new properties.

6ac58a5b8a VSE: Auto-include effect chain for copying and metastrip creation
Part of Code Quality Project outlined in #130975.

This patch eschews warning messages urging the user to "select all
related strips" when copying or creating new metastrips and instead
automatically includes those related strips in the operation.

- Attempting to copy or create a metastrip with no strips selected no
  longer delivers a warning.
- When copying strip(s), if there are related effect chains, they will
  be automatically selected and included in the copy if the operation
  succeeds.
  - The decision to select related strips was intentional, as it allows
    the user to easily see the entire effect chain and thus which strips
    were copied.
- When creating a new metastrip, if there are related effect chains,
  they will automatically be included in the resulting metastrip.
  - This is done using a new
    `SEQ_query_strip_connected_and_effect_chain()` iterator. This
    iterator is only used for metastrips, and not copying, since the
    user may wish to only copy single strips in a connection, but
    connected strips should always stay together in a metastrip/seqbase.
