65166e145b Cleanup: Remove scene frame macros (CFRA et al.)
Removes the following macros for scene/render frame values:
- `CFRA`
- `SUBFRA`
- `SFRA`
- `EFRA`

These macros don't add much, other than saving a few characters when typing.
It's not immediately clear what they refer to, they just hide what they
actually access. Just be explicit and clear about that.
Plus these macros gave read and write access to the variables, so eyesores like
this would be done (eyesore because it looks like assigning to a constant):
```
CFRA = some_frame_nbr;
```

92d7f9ac56 Animation: Add GP layers in regular Dopesheet
Grease Pencil animation channels are now also shown in the Dopesheet
mode of the Dopesheet editor and in the Timeline.

Grease pencil related events are now listened not only by container
`SACTCONT_GPENCIL` (Grease Pencil Dopesheet), but also
`SACTCONT_DOPESHEET` (main Dopesheet), and `SACTCONT_TIMELINE`
(timeline).

A new Animation Filter flag was added: `ANIMFILTER_FCURVESONLY`. For now
this only filters out Grease Pencil Layer channels.

**Implemented:**

- Preview range set: now only considers selected Grease Pencil keyframes
  when `onlySel` parameter is true. Not only this allows the operator to
  work with grease pencil keyframes in main dopesheet, but it also fixes
  the operator in the Grease Pencil dopesheet.
- Translation: allocation (and freeing) of specific memory for
  translation of Grease Pencil keyframes.
- Copy/Paste: call to both Fcurve and GPencil operators, to allow for
  mixed selection. Errors are only reported when both the FCurve and
  GPencil functions fail to paste anything.
- Keyframe Type change and Insert Keyframe: removed some code here to
  unify Grease Pencil dopesheet and main dopesheet code.

- Jump, Snap, Mirror, Select all/box/lasso/circle, Select left/right,
  Clickselect: account for Grease Pencil channels within the channels
  loop, no need for `ANIMFILTER_FCURVESONLY` there.

**Not Implemented:**

- Graph-related operators. The filter `ANIMFILTER_FCURVESONLY` is
  naively added to all graph-related operators, meaning more-or-less all
  operators that used `ANIMFILTER_CURVE_VISIBLE`.
- Select linked: is for F-curves channel only
- Select more/less: not yet implemented for grease pencil layers.
- Clean Keys, Sample, Extrapolation, Interpolation, Easing, and Handle
  type change: work on Fcurve-channels only, so the
  `ANIMFILTER_FCURVESONLY` filter is activated

Graying out these operators (when no fcurve keyframe is selected) can be
done with custom poll functions BUT may affect performance. This is NOT
done in this patch.

**Dopesheet Summary Selection:**

The main summary of the dopesheet now also takes into account Grease
Pencil keyframes, using some nasty copy/pasting of code, as explained
[on devtalk](https://devtalk.blender.org/t/gpencil-layers-integration-in-main-dopesheet-selection-issue/24527).
It works, but may be improved, providing some deeper changes.

011327224e Transform Snap: nearest face snap mode, snapping options, refactoring.
This commit adds a new face nearest snapping mode, adds new snapping
options, and (lightly) refactors code around snapping.

The new face nearest snapping mode will snap transformed geometry to the
nearest surface in world space. In contrast, the original face snapping
mode uses projection (raycasting) to snap source to target geometry.
Face snapping therefore only works with what is visible, while nearest
face snapping can snap geometry to occluded parts of the scene. This new
mode is critical for retopology work, where some of the target mesh
might be occluded (ex: sliding an edge loop that wraps around the
backside of target mesh).

The nearest face snapping mode has two options: "Snap to Same Target"
and "Face Nearest Steps". When the Snap to Same Object option is
enabled, the selected source geometry will stay near the target that it
is nearest before editing started, which prevents the source geometry
from snapping to other targets. The Face Nearest Steps divides the
overall transformation for each vertex into n smaller transformations,
then applies those n transformations with surface snapping interlacing
each step. This steps option handles transformations that cross U-shaped
targets better.

The new snapping options allow the artist to better control which target
objects (objects to which the edited geometry is snapped) are considered
when snapping. In particular, the only option for filtering target
objects was a "Project onto Self", which allowed the currently edited
mesh to be considered as a target. Now, the artist can choose any
combination of the following to be considered as a target: the active
object, any edited object that isn't active (see note below), any non-
edited object. Additionally, the artist has another snapping option to
exclude objects that are not selectable as potential targets.

The Snapping Options dropdown has been lightly reorganized to allow for
the additional options.

Included in this patch:

- Snap target selection is more controllable for artist with additional
  snapping options.
- Renamed a few of the snap-related functions to better reflect what
  they actually do now. For example, `applySnapping` implies that this
  handles the snapping, while `applyProject` implies something entirely
  different is done there. However, better names would be
  `applySnappingAsGroup` and `applySnappingIndividual`, respectively,
  where `applySnappingIndividual` previously only does Face snapping.
- Added an initial coordinate parameter to snapping functions so that
  the nearest target before transforming can be determined(for "Snap to
  Same Object"), and so the transformation can be broken into smaller
  steps (for "Face Nearest Steps").
- Separated the BVH Tree getter code from mesh/edit mesh to its own
  function to reduce code duplication.
- Added icon for nearest face snapping.
- The original "Project onto Self" was actually not correct! This option
  should be called "Project onto Active" instead, but that only matters
  when editing multiple meshes at the same time. This patch makes this
  change in the UI.

302b04a5a3 VSE: Improved Retiming system
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.

9ccc21dde3 VSE preview transform autokeying improvements
NOTE: this patch originated in T98015 which was split into multiple
reports. While it could be split into multiple patches these are very
much related so keeping as one for now

This patch fixes the following issues:

[1] autokeying transforms in preview only creates keyframes if there is
an FCurve already
[2] autokeying transforms in preview only creates keyframes for
rotation/scale if rotating/scaling around cursor (should keyframe
position as well)
[3] autokeying transforms in preview does not work during animation
playback

For [1], a param was added to `ED_autokeyframe_property` which can tweak
its default behavior of only creating keyframes on already keyed
properties (which was fine because this is mostly called from buttons
where this behavior is desired). Callers such as gizmos (or the VSE in
our case) can use this additional param so that keyframes are also
created on "not-yet-keyframed" properties.

For [2], the pivot is checked and position properties also keyed if
necessary (which is also consistent with the way objects are keyed in
the 3DView)

For [3], `animrecord_check_state` was changed to be able to work on
scenes as well and the transform system in the VSE preview was made
aware of the screen's `animtimer`.

NOTE: there are still things to be improved for keyframing in the VSE,
the most obvious is probably a `keyframe_insert` operator (with
keyingsets)

3772dda4ab Refactor: Snap-related. Clarified attribute names and refactored #defines into enums
The transformation snapping code contains a bunch of `#define`s, some ambiguously or incorrectly named attributes.  This patch contains refactored code to improve this.  This patch does (should) not change functionality of snapping.

Clarified ambiguously / incorrectly named attributes.

  - "Target" is used to refer to the part of the source that is to be snapped (Active, Median, Center, Closest), but several other areas of Blender use the term "target" to refer to the thing being snapped to and "source" to refer to the thing getting snapped.  Moreover, the implications of the previous terms do not match the descriptions.  For example: `SCE_SNAP_TARGET_CENTER` does not snap the grabbed geometry to the center of the target, but instead "Snap transforamtion center onto target".
  - "Select" refers to the condition for an object to be a possible target for snapping.
  - `SCE_SNAP_MODE_FACE` is renamed to `SCE_SNAP_MODE_FACE_RAYCAST` to better describe its affect and to make way for other face snapping methods (ex: nearest).

Refactored related `#define` into `enum`s.  In particular, constants relating to...

  - `ToolSettings.snap_flag` are now in `enum eSnapFlag`
  - `ToolSettings.snap_mode` are now in `enum eSnapMode`
  - `ToolSettings.snap_source` (was `snap_target`) are now in `enum eSnapSourceSelect`
  - `ToolSettings.snap_flag` (`SCE_SNAP_NO_SELF`) and `TransSnap.target_select` are now in `enum eSnapTargetSelect`

As the terms became more consistent and the constants were packed together into meaningful enumerations, some of the attribute names seemed ambiguous.  For example, it is unclear whether `SnapObjectParams.snap_select` referred to the target or the source.  This patch also adds a small amount of clarity.

This patch also swaps out generic types (ex: `char`, `short`, `ushort`) and unclear hard coded numbers (ex: `0`) used with snap-related enumerations with the actual `enum`s and values.

Note: I did leave myself some comments to follow-up with further refactoring.  Specifically, using "target" and "source" consistently will mean the Python API will need to change (ex: `ToolSettings.snap_target` is not `ToolSettings.snap_source`).  If the API is going to change, it would be good to make sure that the used terms are descriptive enough.  For example, `bpy.ops.transform.translate` uses a `snap` argument to determine if snapping should be enabled while transforming.  Perhaps `use_snap` might be an improvement that's more consistent with other conventions.

This patch is (mostly) a subset of D14591, as suggested by @mano-wii.

Task T69342 proposes to separate the `Absolute Grid Snap` option out from `Increment` snapping method into its own method.  Also, there might be reason to create additional snapping methods or options.  (Indeed, D14591 heads in this direction).  This patch can work along with these suggestions, as this patch is trying to clarify the snapping code and to prompt more work in this area.

7afcfe111a VSE: Make time operations self-contained
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.

So the constraint "selection" is now done in two ways:

cc0c4c17f0 Fix T95752: crash 'Select Linked' after loopcut in multiobject editmode
This was reported explicitly for originally being in face selectmode,
but could also crash when in vertex selectmode (when doing multiple
cuts).

The reason here is that `MESH_OT_loopcut` switches to edge select mode
(needed for `TRANSFORM_OT_edge_slide`, done in `ringsel_finish`), but was
only doing this on the active object's editmesh, all other participating
meshes would keep their selectmode which would now be out of sync with
both the active object's editmesh and scene settings for these.

This causes problems later in 'Select Linked'. Here, a mixture of
objects are used. First the viewcontext is set up with the active
object, then all participating objects are iterated (changing the
viewcontext to another object), then `unified_findnearest` would use that
changed viewcontext which would now contain the last object iterated. To
repeat: this could now have a different selectmode than the active
object which is later **again** used to get the nearest `BMElem` from in
`EDBM_elem_from_selectmode`. So in the failing case, we could get an
edge (but no face because of edge selectmode) from `unified_findnearest`,
`EDBM_elem_from_selectmode` would return NULL though (edge provided, but
in face selectmode), leading to the crash.

To solve this I assume it is best to change selectmode on all
participating meshes in multi-object editmode loopcut if necessary so
these are always in sync for following operations.
Alternatively, `Select Linked` (and probably lots more operators) would
have to be tweaked to pay closer attention which object is really used
to get selectmode from.

Note the selectmode is actually set back from edge selectmode in certain
cases (see `USE_LOOPSLIDE_HACK`), this patch changes that as well to act
on all participating meshes.

When height is limited, it is defined by space occupied by strips,
but at least channels 1 to 7 will be always visible. This allows it to
easily overview timeline content by zooming out to maximum extent in Y
axis and panning in X axis.

More channels can be "created" on demand by moving strip to higher
channel. When strip is removed and highest channel becomes empty, view
will stay as is until it is moved down. Then new highest point is
remembered and it is not possible to pan upwards until strip is moved to
higher channel.

Limiting takes into account height of scrubbing and markers area as
well as scrollers. This means that when zoomed out to maximum extent,
no strips are obstructed by fixed UI element.

d30f701e84 Cleanup: Turn some 'eTFlag' into macros
Some of the enum values are a mixture of others and make it difficult

35dc4ba9e2 Fix T97401: Snap options ignored for Nurbs surfaces
The editing data of a `SURF`s is similar to that of Curves and should be supported for snapping.

But unlike Curve objects, for snapping, only support the nurb points if the object is in edit mode.

This matches the solution for Meshes and avoids having to create a kind
of "boundbox" for the SURF nurb points.
