Use existing function `screen_animation_region_supports_time_follow` in
`areas_do_frame_follow` to check region-space types in case of: follow current
frame is enabled and playback is moved with arrow keys
Noticed this while checking #110620

Move the public functions from the editors/object (`ED_object.hh`)
header to the `blender::ed::object` namespace, and move all of the
implementation files to the namespace too. This provides better code
completion, makes it easier to use other C++ code, removes unnecessary
redundancy and verbosity from local uses of public functions, and more
cleanly separates different modules.
See the diff in `ED_object.hh` for the main renaming changes.

This could happen when e.g. overriding context with just the area.
Now add poll functions that check for an active region when running
operators that require a region.
The fix is similar to 72688791dc
Alternatively, we could have a fix similar to a8892c7264 (getting the
correct region from the area), this would require less setup by
scripters, however for some operators the usage of the region is a
little further down the line, so implementation would be a bit more
involved. Also: for some of the operators, this would have to be done in
both `invoke` and `exec` (so would be more duplicate code changes).

When areas are dragged very small we want the (visual) vertical minimum
to equal header height, and the horizontal minimum to be equal to the
Properties nav area width. This PR just makes these adjust correctly
with changes of resolution scale and line width.

This was reported as #93410 & fixed with [0] however the fix didn't
help for animated logic (with region overlap enabled).
Resolve by adding a function ED_region_visibility_change_update_ex which
is called by the animated and non-animated region hiding functions.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
There are operators in Blender that allow the user to import multiple
files at the same time, however this functionality is only implemented
when importing with blender's file browser, drag and drop files only
takes first selected file.
The patch adds support for drag and drop multiple files.
Notes:
* The files are filtered according to the extension of the first
selected file.
* Not all operators that import files support importing multiple files,
so they will still import one.
* Changes must be made to allow importers to read all file paths.
This will be used in upcoming drag & drop import.

# Issue
Having a lot of keys in your scene can dramatically slow down the Dope Sheet.
That is because everytime the Dope Sheet is redrawn,
the Keylists have to be recomputed.
In the case of the summary channel, that means going through
all keyframes of all the `FCurves` and adding them to the keylist.
That eats up 95% of the time it takes to draw a frame.
# This PR
It's not a perfect solution, rather it solves the performance issue
for the case when you are not displaying all keys.
Instead of going through all the keys, only add the
keys visible in the view to the keylist.
This speeds up the Dope Sheet significantly
depending on the zoom level.
This also improves the responsiveness when selecting and transforming keyframes.
# Performance changes
The function measured is `ED_channel_list_flush`
which is responsible for building the keylists and drawing them.
The test setup contains 62 bones with all
10 channels keyed (location, rot quaternion, scale) on 6000 frames.
So 3.720.000 keys. The heavier the dataset the bigger the performance impact.
The data was recorded with only the Dope Sheet open, and 3 channels visible
* Summary
* Object
* Action
The more channels are visible, the greater the performance gain. This can be seen in the video.
| visible range | before | after |
| - | - | - |

| 400f | 250ms | 18ms |

If "Region Overlap" was disabled, the region coordinate calculations
would end up placing the header on the bottom, taking space away from
the main asset shelf region. This is because the header was abusing the
`RGN_SPLIT_PREV` flag a bit, because it gave the desired behavior of
hiding the regions together. This worked well because the regions
wouldn't actually do the splitting when one used region overlap and the
other not. But disabling region overlap would bring the splitting
usually enabled with the `RGN_SPLIT_PREV` flag.
This PR removes the `RGN_SPLIT_PREV` flag from the asset shelf header.
Instead a new flag is introduced to only enable the behavior of
`RGN_SPLIT_PREV` of hiding a region together with the previous one. So
the header stays at the top of the region, and labels stay visible.
The new flag is added to the `ARegion.alignment` flags, even though it's
more related to behavior than alignment. However this is more
convenient, and keeps it together with related flags.
The last good commit was 8474716abb.
After this commits from main were pushed to blender-v4.0-release. These are
being reverted.
Commits a4880576dc from to b26f176d1a that happend afterwards were meant for
4.0, and their contents is preserved.
If region overlap was disabled, the full background of the asset shelf
header would be drawn, unlike usually where we keep the space between
button sections transparent. But resizing the region by dragging wasn't
possible from the space between the button sections, even though the
header was fully opaque.
Button section drawing should only be respected when region overlap is
enabled.
Design task: #93551
This PR replaces the auto smooth option with a geometry nodes modifier
that sets the sharp edge attribute. This solves a fair number of long-
standing problems related to auto smooth, simplifies the process of
normal computation, and allows Blender to automatically choose between
face, vertex, and face corner normals based on the sharp edge and face
attributes.
Versioning adds a geometry node group to objects with meshes that had
auto-smooth enabled. The modifier can be applied, which also improves
performance.
Auto smooth is now unnecessary to get a combination of sharp and smooth
edges. In general workflows are changed a bit. Separate procedural and
destructive workflows are available. Custom normals can be used
immediately without turning on the removed auto smooth option.
**Procedural**
The node group asset "Smooth by Angle" is the main way to set sharp
normals based on the edge angle. It can be accessed directly in the add
modifier menu. Of course the modifier can be reordered, muted, or
applied like any other, or changed internally like any geometry nodes
modifier.
**Destructive**
Often the sharp edges don't need to be dynamic. This can give better
performance since edge angles don't need to be recalculated. In edit
mode the two operators "Select Sharp Edges" and "Mark Sharp" can be
used. In other modes, the "Shade Smooth by Angle" controls the edge
sharpness directly.
### Breaking API Changes
- `use_auto_smooth` is removed. Face corner normals are now used
automatically if there are mixed smooth vs. not smooth tags. Meshes
now always use custom normals if they exist.
- In Cycles, the lack of the separate auto smooth state makes normals look
triangulated when all faces are shaded smooth.
- `auto_smooth_angle` is removed. Replaced by a modifier (or operator)
controlling the sharp edge attribute. This means the mesh itself
(without an object) doesn't know anything about automatically smoothing
by angle anymore.
- `create_normals_split`, `calc_normals_split`, and `free_normals_split`
are removed, and are replaced by the simpler `Mesh.corner_normals`
collection property. Since it gives access to the normals cache, it
is automatically updated when relevant data changes.
Addons are updated here: https://projects.blender.org/blender/blender-addons/pulls/104609
### Tests
- `geo_node_curves_test_deform_curves_on_surface` has slightly different
results because face corner normals are used instead of interpolated
vertex normals.
- `bf_wavefront_obj_tests` has different export results for one file
which mixed sharp and smooth faces without turning on auto smooth.
- `cycles_mesh_cpu` has one object which is completely flat shaded.
Previously every edge was split before rendering, now it looks triangulated.

View2D isn't initialized in these regions yet, which is a valid state
for hidden regions. So consider that when calculating the region zoom
factor in the region scale operator.
Code has special handling so that only the first of two split regions
needs to be flagged as hidden. If the second one is also flagged that
can have some unwanted side-effects. Code to add the region resizing
edges relied on the region visibility flags though, rather than the
visibility check that respects this handling of split region hiding. So
code would run that is only intended for un-hidden regions.
Draw the background of the asset shelf header fully transparent, with an opaque
background with rounded corners behind sections containing buttons. This
reduces the visual space consumed by the asset shelf, and makes the header
follow a tabbed folder metaphor better. Also, this works much better with our
click-through feature, where transparent parts of regions without buttons are
passed through the region under it (we might want to consider unifying code
here a bit).
The edge to drag for region resizing respects the transparent sections.
When there is little space between sections, the sections get merged so that
there are no small gaps in the bar.

Note that the core of this is implemented in a generic way, so this can be
reused for other regions.

Rather than always snapping the region size to the closest multiple of
the row height, remember the amount of rows displayed after the user
resized the region, and try to preserve that. This gives a lot more
predictable behavior, especially when the "Show Names" option is toggled
on and off, and the region resizes in response. With the old method the
amount of visible rows could change multiple times while toggling.
This also enables us to clamp the amount of rows (e.g. while the preview
size is increased and the region becomes too large for the area; or,
when a catalog tab is activated with fewer assets and thus fewer rows)
but still restore the amount of rows the user chose earlier, as soon as
possible.

Update of the following operators to take into account
grease pencil frames :
* SCREEN_OT_keyframe_jump, which jumps to the average
position of the selected frames, and
* ACTION_OT_frame_jump, which jumps to the previous/next
frame in the active channel.

Users expect to be able to scale the uppermost edge of the asset shelf,
which actually belongs to the asset shelf header region only. So it
would only work to hide/unhide this. They expect this because they seem
like one region, but they are actually implemented as two (to have
separate layout and scrolling mostly).
This adds a region flag so that scaling a region can actually affect the
previous one instead. Something similar is already used for split
regions.
Part of #107881.
There are a couple of functions that create rna pointers. For example
`RNA_main_pointer_create` and `RNA_pointer_create`. Currently, those
take an output parameter `r_ptr` as last argument. This patch changes
it so that the functions actually return a` PointerRNA` instead of using
the output parameters.
This has a few benefits:
* Output parameters should only be used when there is an actual benefit.
Otherwise, one should default to returning the value.
* It's simpler to use the API in the large majority of cases (note that this
patch reduces the number of lines of code).
* It allows the `PointerRNA` to be const on the call-site, if that is desired.
No performance regression has been measured in production files.
If one of these functions happened to be called in a hot loop where
there is a regression, the solution should be to use an inline function
there which allows the compiler to optimize it even better.
