This adds a structure, `ABCReadParams`, to store some parameters passed
to `ABC_read_mesh` so we avoid passing too many parameters, and makes it
easier to add more parameters in the future without worrying about
argument order.

Box, Circle and Lasso select were not taking into account if a
mask(point) was parented; selection was only succeeding in the original
place.
Now check coordinates from evaluated mask (points) instead while
setting selection flags and DEG tagging still happens on the original ID.

Extremely subttle bug that would only appear in some specific
circumstances, would cause memfile undo writing code to falsely detect
some ID as changed because it would get the wrong 'starting point' of
comparison with existing previous memfile step.
See T85756 for detailed explanation and reproducible case.

This adds a new node editor overlay that helps users to see where
named attributes are used. This is important, because named
attributes can have name collisions between independent node
groups which can lead to hard to find issues.

When GPU subdivision is enabled the mesh objects remain unsubdivided on
the CPU side, and subdivision should be requested somewhat manually (via
`BKE_object_get_evaluated_mesh`).
When referencing an object, the Object Info node calls
`bke::object_get_evaluated_geometry_set` which first checks if a Geometry
Set is present on the object (unless we have a mesh in edit mode). If so
it will return it, if not, the object type is discriminated, which will
return a properly subdivided mesh object via `add_final_mesh_as_geometry_component`.
The unsubdivided mesh is returned because apparently the check on the
Geometry Set always succeeds (as it is always set in `mesh_build_data`).
However, the mesh inside this Geometry Set is not subdivided.
This adds a check for a MeshComponent in this Geometry Set, and if one
exists, calls `add_final_mesh_as_geometry_component` which will ensure
that the mesh is subdivided on the CPU side as well.

Originally was noticed when using a linked background scene and a scene
camera from another (local) scene.
The root issue was that relation from view layer to object's base flags
evaluation was using wrong view layer. This is because the relation was
created between object and currently built view layer, and it only was
happening once (since the object-level relations are only built once).
Depending on order in which `build_object` was called it was possible
that relation from a wrong view layer was used.
Now the code is better split to indicate which parts of object relations
are built when object comes from a base in the view layer, and which ones
are built on indirect linking of object to the dependency graph.
This patch makes relations correct in the cases when the same object is
used as a base in both active and set scenes. But, the operation which
handles object-level flags might not behave correctly as there is no
known design of what is the proper thing to do in this case. Making a
clear design and implementation of case when object is shared between
active and set scene is outside of the scope of this patch.

Prefer using immVertex3f when 3D shaders are used for 2D rendering due to overhead of vertex padding in hardware. CPU overhead is negligible.

Add a new operator, "Start Tweaking Strip Actions (Full Stack)", which
allows you to insert keyframes and preserve the pose that you visually
keyed while upper strips are evaluating,
The old operator has been renamed from "Start Tweaking Strip Actions" to
"Start Tweaking Strip Actions (Lower Stack)" and remains the default for
the hotkey {key TAB}.
**Limitations, Keyframe Remapping Failure Cases**:
1. For *transitions* above the tweaked strip, keyframe remapping will
fail for channel values that are affected by the transition. A work
around is to tweak the active strip without evaluating the upper NLA
stack.
It's not supported because it's non-trivial and I couldn't figure it
out for all transition combinations of blend modes. In the future, it
would be nice if transitions (and metas) supported nested tracks
instead of using the left/right strips for the transitions. That
would allow the transitioned strips to overlap in time. It would also
allow N strips to be part of the (previously) left and right strips,
or perhaps even N strips being transitioned in sequence (similar to a
blend tree). Proper keyframe remapping through all that is currently
beyond my mathematical ability. And even if I could figure it out,
would it make sense to keyframe remap through a transition?
//This case is reported to the user for failed keyframe insertions.//
2. Full replace upper strip that contains the keyed channels.
//This case is reported to the user for failed keyframe insertions.//
3. When the same action clip occurs multiple times (colored Red to
denote it's a linked strip) and vertically overlaps the tweaked
strip, then the remapping will generally fail and is expected to
fail.
I don't plan on adding support for this case as it's also non-trivial
and (hopefully) not a common or expected use case so it shouldn't be
much of an issue to lack support here.
For anyone curious on the cases that would work, it works when the
linked strips aren't time-aligned and when we can insert a keyframe
into the tweaked strip without modifying the current frame output of
the other linked strips. Having all frames sampled and the strip
non-time aligned leads to a working case. But if all key handles are
AUTO, then it's likely to fail.
//This case is not reported to the user for failed keyframe
insertions.//
4. When using Quaternions and a small strip influence on the tweaked
Combine strip. This was an existing failure case before this patch
too but worth a mention in case it causes confusion. D10504 has an
example file with instructions.
//This case is not reported to the user for failed keyframe insertions. //
5. When an upper Replace strip with high influence and animator keys to
Quaternion Combine (Replace is fine). This case is similar to (4)
where Quaternion 180 degree rotation limitations prevent a solution.
//This case is not reported to the user for failed keyframe insertions.//

This patch fixes a typo in commit e59f754c169d which incorrectly uses `GPU_TEXTURE_ARRAY` instead of `GPU_FORMAT_COMPRESSED`.
`GPU_FORMAT_COMPRESSED` and `GPU_TEXTURE_ARRAY` both currently evaluate to 16, so this patch does not change anything functionally; however, this patch will prevent issues from arising in the future.

Add operator to select markers left/right of the current frame
(including the current frame).
`bpy.ops.marker.select_leftright(mode='LEFT', extend=False)`
`mode` can be either 'LEFT' or 'RIGHT'.
The naming and defaults of the above variables match similar operators
(e.g., `bpy.ops.nla.select_leftright`)
This also adds a new sub-menu to the Marker menu found in animation
editors, exposing both the new `bpy.ops.marker.select_leftright`
operator as well as the `bpy.ops.marker.select_all` operator.
Despite the name "Before Current Frame" and "After Current Frame", it
also selects a marker that falls on the current from for both of the
modes. This is to match the behavior found in the `nla.select_leftright`
operator.

Unlike regular selection cycling that is activated when clicking again
in the same location, object mode would cycle to another object
if the object that was selected happened to already be active.
This made it impossible to click-drag to tweak the active object
if there were other objects behind it as those would be activated first.

Was adding 1 to dietime twice in init_particle_interpolation.
|
|
Particles baked into memory would never load the final frame because
of an off-by-one error calculating the particles `dietime`.
This value indicates the frame which the particle ceases to exist but
was being set to the end-frame which caused this bug as the scenes
end-frame is inclusive.
While the last frame was properly written and read from memory,
the `dietime` was set to the last frame causing all the particles to be
considered dead when calculating the cached particle system.

These were missed in previous passes. Also remove some logic
in `draw_hair.c` that was redundant after f31c3f8114616bb8964c8e7.
|
|
The GPU evaluation for curves will have to change significantly from the
current particle hair drawing code, due to its more general use cases
and support for more curve types. To simplify that process and avoid
introducing regressions for the rendering of hair particle systems,
this commit splits drawing functions for the curves object and
particle hair.
The changes are just inlining of functions and copying code
where necessary.

When tangent are computed from generated coordinates, the result for GPU
subdivision would be compressed to 16-bit when it shouldn't.

Problem is that the orco layer was not taken care of by the GPU

Use Alt-Slash to remove objects from local-view (was M prior to [0]),
following the convention of using Alt to perform the reverse of an
action. Also remove the confirmation menu as this key as it can be
undone and it's not likely to be pressed by accident.
This can be useful to quickly subtract items from a complex selection
with items that only become visible when entering local-view.
The M key was originally used in 2.4x since moving between layers wasn't
possible. Now moving between collections is possible in local-view
the keys collided.

When wireframe mode is turned on, the subdivision edges not originating
from coarse edges were also drawn as regular edges, which would confuse
users trying to select them. These should not be drawn in edit mode,
only in object mode when optimal display is turned off (matching the CPU
subdivision case).

When displaying a deform modifier in edit mode, a cached
array of positions is used. Parallelizing bounds calculation when
that array exists can improve the framerate when editing slightly
