Currently, sometimes shader code generation fails because the code of top-level
nodes is interleaved with the code of a repeat zone. See #147747 for more
details.
Previously, the code-generation order was just the standard toposort of the node
tree, but it does not guarantee that all nodes in a zone are next to each other.
Also, it can't easily, because the zone detection itself depends on the
toposort. This patch implements another sorting step on top of the default
toposort. It packs nodes in zones together without changing the validity of the
toposort.
This is an alternative to #147999.

Quick tooltips immediately show a word or two and then shows more
detailed information after a pause. It is possible to have these two
things shows at differing positions (vertically or horizontally) and
therefore jiggle. Some padding code uses the width and height and half
of a padding amount, which can result in differing values if the first
width or height is an odd amount but the second is even, or vice versa.
This happens quite infrequently and depends on the user scale. This PR
just replaces one line that does the padding in a way that results in
consistent values.

The cause was a missed case from #130440 where
`use_nla_remapping = true` was being unconditionally passed to
`fcurve_to_keylist()` rather than determining the value with
`ANIM_nla_mapping_allowed()` as it should have been.
The fix is simply to use `ANIM_nla_mapping_allowed()` instead of
unconditionally passing `true`.
This PR also changes an outdated comment to properly explain why `adt`
was null in the first place (which is precisely to catch bugs like
this).

Currently, the scene strip preview uses the existing dependency
graph built for that scene. This was not a big issue before
the sequencer scene was introduced, because the user would have
to create two main Blender windows to run into problems.
Now with the sequencer scene, it's possible to look at the scene
of a scene strip within the same window.
When the user is editing the scene (e.g. moving an animated object)
any open sequencer preview will cause the edits to be flushed.
This can e.g. result in visual jumping of animated objects, and more.
This PR attempts to fix the issue in a straightforward way: Use
a separate dependency graph for rendering the sequencer preview.
While this fixes the immediate issues, there are some consequences:
* The memory usage of the scene dependency graph _can_ roughly
double (since there are now likely two instances of the same
dependency graph). Because of implicit sharing, unmodified data
will not be copied. But for example modifiers on meshes would
currently create two copies of the evaluated data in the two
dependency graphs.
* Creating the dependency graph can be costly, which will cause the
first frame that the scene has to render to be slower.
Note: The current code changes some properties of the original scene
like the frame, subframe etc. before rendering and then restores
the original state. In theory, this part of the code can be removed,
but may be a bit too risky for just a fix. This should be improved
at a later stage.

This speeds up drawing of the UI of the Geometry Nodes modifier, especially for
very large node trees like in the files from #146949.
A couple previous commits and #147883 speed up the inferencing significantly
already. However, there is a certain limit to how fast this can be on large
complex node trees. While there is some more optimization potential, this patch
implements a cache on the Geometry Nodes modifier level. This means that as long
as the inputs and the node tree stays the same, the inferencing only has to
happen once, instead of on every redraw.
The main difficulty with this cache is that we don't have a good way to
invalidate it eagerly when any of the modifier inputs changes. That can
hopefully become simpler with #138117. For now, we have to check all input
values on redraw to check if anything has changed compared to the last redraw
and recompute the cache if there is any change.

The problem was that the Pen Tool would not set the `Resolution` attribute
and so when the `Resolution` attribute didn't exist, the newly added curve
would default to a value of 0, which would then lead to an Assert.
This problem would also effect `Curves` Objects.

This breaks tests (and the VR addon itself of course).
Needs to be done differently, will create new PR for proper fix.
This reverts commit 0c22ef5ae7.
When a Cycles render is uneven (E.g. a small portion of the image takes
significantly longer to render than the rest of the image), then GPUs
typically suffer from poor performance due to low occupancy unless a
large number of samples is scheduled to compensate for that small
complex region.
Due to how Cycles render scheduler is setup, Cycles tries to
increase GPU occupancy by increasing the number of scheduled samples,
but also balance render preview update time by scaling back
the number of scheduled samples based on the previous workloads time
per sample to try and fit within the target update time.
However using the previous workloads time per sample to scale back the
scheduled number of samples gives suboptimal results because the
previous workloads time per sample is usually not representative of the
new time per sample that occurs as GPU occupancy increases, because
increasing GPU occupancy typically results in reduced time per samples.
This commit improves on this issue by assuming that increasing GPU
occupancy linearly improves performance, and adjusts the function
that scales back the sample count to fit within a specific update
window to use this assumption. This leads to Cycles increasing the
amount of work scheduled onto the GPU quicker at the beginning of
uneven/low occupancy scenes, generally leading to improved performance,
especially when rendering at low sample counts or with strict
time limits.

Move the versioning code that switches the Timeline editor to Dope

In the Viewport VR Preview, an unusual and complicated import
manipulates sys.path to import a class from a file that is already
importable anyway.
There is no documented reason for this, and the common way to subclass an RNA type in python is by using its `bpy.types....` registered class, _not_ by directly subclassing the python type used to declare/register the parent type.

Only draw the Summary backdrop color when the Summary channel has been
expanded. This prevents the default used-to-be-timeline Dope Sheet
from showing a big red bar at the bottom of the window.
The channel box backdrop (when the channel bar is expanded) also
follows this, so when expanded it is red as before, and when collapsed
it is dark grey.

Blender cannot handle bones with (near) zero length. Prior to this
commit such bones were deleted when exiting Armature Edit mode. Now
they are kept and elongated so that they are numerically stable (or at
least they should be, given the threshold to the length that was
already in place).
To avoid the elongation from impacting the position of child bones,
they are disconnected from the tiny bone.
Apart from that it's quite nice for users that Blender no longer
silently deletes bones, this is also useful for the USD importer, as
it can import bones and expect them to exist afterwards (see
#147048).
Note: this only impacts armatures with bones of length ≤ 0.000001
units.

Rename modules in `./scripts/modules/` to use an underscore prefix to
make it clear they aren't intended to be part of public API's. This
also means there is no implication that these modules should be stable,
allowing us to change them based on Blender's internal usage.
The following modules have been marked as private:
- `animsys_refactor`
- `bl_console_utils`
- `bl_i18n_utils`
- `bl_previews_utils`
- `bl_rna_utils`
- `bl_text_utils`
- `bl_ui_utils`
- `bpy_restrict_state`
- `console_python`
- `console_shell`
- `graphviz_export`
- `keyingsets_utils`
- `rna_info`
- `rna_manual_reference`
- `rna_xml`
Note that we could further re-arrange these modules
(under `_bpy_internal` in some cases), this change is mainly to mark
them as private, further changes can be handed on a case-by-case basis.

Since VSE HDR preview was implemented (18110744a2), the preview image
is put into RGBA 16F format "color texture", and the overlay
(checkerboard, grids etc.) is put into RGBA 8U format "overlay texture".
This was rendering the color image as NON premultiplied alpha in
the viewport color texture, which is not what happens in other places
(e.g. image space).
Later commit (c279d894db) fixed transparency of the overlay texture,
in order to make pure emissive (color non zero, alpha zero) colors
from EXR files show up in VSE preview. However that exposed the issue
that underlying color texture is not premultiplied.
Fix this by premultiplying the output color in gpu_shader_display_transform
that is used by VSE preview. This is done at the end of the shader
isntead of using fixed function blending, since premultiplication needs
to happen in a way that preserves pure-emissive colors.

We have icons that represent specific individual collections. like
Icon_Outliner_Collection for a default (uncolored) collection, and
Icon_Collection_color_x for ones with colors. For "collections" as a
general thing though we have icon_group. Sometimes we confuse the two,
for example the list of tabs to show in Properties uses a different
icon than the actual category icon. This PR fixes the complaint by
using the correct icon for each of these purposes.

In OSL custom cameras, the current aperture size depends on the focal
length of the Blender camera, even though it is not usable by the
shader. This gives incoherent values to the depth of field.
To ignore this factor, this commit makes the custom camera behave the
same as the orthographic camera, by not being multiplied by the focal
length.
To compensate for that, the multiplication must happen inside the
shader. This adjustment was done in the advanced camera shader
template.

The previous commit 80e8493c11 was incorrect. I must have
tested it incorrectly, because `BLI_path_contains` only tests the
beginning of the path. Instead just make the shorter asset path
native, and explicitly use StringRef for the test.
The RNA property had an incorrect update callback assigned. The
update callback assumed the RNA pointer data was a node rather
than a node's viewer item.
I think the special handling for string input node, added in #139478,
was broken by #146033. The early check for src_value (`if (!src_value)`)
caused the string-specific logic to be skipped. This PR moves the
string-specific handling before the src_value check.

The flag that skips objects for snapping (`BA_SNAP_FIX_DEPS_FIASCO`) is
set for all objects that have a `DEG_OB_COMP_TRANSFORM` relation.
However, when the **Affect Only Parent** option is enabled, children
are not transformed and therefore could still be snapped to.
Despite this, the `DEG_OB_COMP_TRANSFORM` dependency remains present on
them.
To address this, a new callback was introduced that skips
Transform-to-Transform dependencies while preserving
Transform-to-Geometry dependencies in this scenario.
This approach may introduce some false positives, leading to spurious
dependency cycles (e.g., when constraints are involved).
Nevertheless, the trade-off favors accepting these false positives
rather than disabling the feature altogether.
Also make non-functional change that just removes a flag before the snap
loop, thus avoiding checking if the flag exists inside the loop.

There was a bug in the move_weld_profile_planes function where
it would only move the profile plane involved in a "weld" if
certain vectors were not too small (less than BEVEL_EPSILON in
length). The intent of the code was just to avoid problems with
zero length normals (post normalization), and the normalize_v3
function indicates that with an exact 0.0f return, so there was
no need for an epsilon test.
The example file in the issue had a small-scale model (100 times
smaller than typical), which ended up causing the old code to
prevent moving the profile plane to where it belongs.
