When the displacement space is set to SHD_SPACE_WORLD, the GLSL method
"node_displacement_world" is used instead of the "node_displacement_object" method. The two GLSL methods:
```
void node_displacement_object(
float height, float midlevel, float scale, vec3 N, mat4 obmat, out vec3 result)
{
N = (vec4(N, 0.0) * obmat).xyz;
result = (height - midlevel) * scale * normalize(N);
result = (obmat * vec4(result, 0.0)).xyz;
}
void node_displacement_world(float height, float midlevel, float scale, vec3 N, out vec3 result)
{
result = (height - midlevel) * scale * normalize(N);
}
```
In contrast to the "node_displacement_object" method, the "node_displacement_world"
does not require an "obmat" parameter. Attempting to still pass "GPU_builtin(GPU_OBJECT_MATRIX)"
as additional parameter will result in a memory leak. The "GPUNodeLink" allocated in
the "GPU_builtin" method will never get released.
Fixes T83941 Memory leak when using the Displacement shader node in Eevee with the displacement
space set to "World Space"
This change removes copy-on-write operations from ID nodes which do not
need copy-on-write.
Should be no functional changes, as before the copy-on-write operation
would do nothing for those nodes anyway.
Building IDs which are not covered by copy-on-write process was not
implemented, which was causing parameters block not present, and, hence
causing crashes in areas which expected parameters to present.
First part of this change is related on making it so Copy-on-Write is
optional for ID nodes in the dependency graph.
Second part is related on using a generic builder for all ID types
which were not covered by Copy-on-Write before.
The final part is related on making it so build_id() is properly
handling ParticleSettings and Grease Pencil Data. Before they were not
covered there at all, and they need special handling because they do
have own build functions.
Not sure it worth trying to split those parts, as they are related to
each other and are not really possible to be tested standalone. Open
for a second opinion though.
Possible nut-tightening is to re-organize build_id() function so
that every branch does return and have an assert at the end, so that
missing ID type in the switch statement is easier to spot even when
using compilers which do not report missing switch cases.
As for question "why not use default" the answer is: to make it more
explicit and clear what is a decision when adding new ID types. We do
not want to quietly fall-back to a non-copy-on-write case for a newly
added ID types.

Previously this relied on the dependency graph to detect changes in the screen
datablock, which would then notify the renderers. This was rather indirect an
not even really by design. Instead use notifiers to tag specific 3D viewports
to be updated.
Includes changes to BKE_scene_get_depsgraph to accept a const Scene pointer.
Testing if this works correctly requires adding back commits 81d444c and 088904d,

The grease pencil merge depth shader is designed to only work correctly
in octographic mode. The uv coordinates used `noperspective` attribute.
Somehow this doesn't lead to render artifacts on most platforms and was
only detected on OSX + AMD cards.
This fix would calculate the uv coordinate inside the fragment shader
and isn't passed along from the vertex shader.
Thanks to Sebastián Barschkis for providing the hardware and time and
Clément Foucault for helping out with the final fix.

Commit 6e74a8b69f changed the denoiser input passes default to
include the normal pass. This does not always produce optimal images though, hence why the
default was previously set to only include the color and albedo passes. This restores that behavior, so
that viewport denoising with OptiX produces the same results as before.
This commit fixes T84588's second issue. The `particle` parameter was
declared optional in the Python API of `bpy.types.ParticleSystem.uv_on_emitter`
due to a typo in the RNA definition. This commit marks it as required.

When this behavior was added it made sense,
since then show_edges has changed to make edge-display more subtle
(see 1a4b60c30d) instead of removing
edge-selection display entirely.
For jpeg, an image.resolution was always based on the default 72dpi, now
read the pixel density from the jpeg_decompress_struct, convert
according to unit and store in IMBuf's ppm.
Not 100% sure of all implications tbh., files I have checked seem to work

If a force field was of type "Texture", any changes of that texture (e.g.
its type - as reported in T85139 - or also its properties) were not

accordingly.

The outline for the active modifier was abusing the property search
match theme color, as noted in a comment. This commit adds a new
theme color in RNA specifically for the active modifier outline.
This enum is only used by the node. So it does not need to be declared outside
the scope of its function.
Originally I thought this may be relevant to the collection info node as well,
but the patch for it is defining its own enums.
The issue was that the `offset` in `dst_span[offset]` was out of bounds
when the domain size is 0. The fix is to simply skip copying attributes
in that case.
This reverts commit 76fd41e9db. This should have
been reverted along with 0f95f51361, since this
change by itself is causing crashes when the depsgraph accesses a non-existent
copy-on-write component.

For buttons that edit array properties, the soft min/max and slider ranges are
based on the range of all values in the array. However for alpha this does not
make much sense, the only reasonable range is 0..1 even when there are RGB
values larger than 1. So treat alpha as an individual property.
There are two issues here. First, like in T81988 there are cases
where the modifier would deform some vertices immediately after
bind. This is caused by wrong assumptions in the code about the
possible relative angles between various vectors, which can cause
negative weights that don't blend correctly to appear.
Specifically, it seems originally the code assumes that the
centroid-point vector in the polygon plane lies somewhere
between the mid-edge vectors. This is however not necessarily
the case for distant vertices, because the polygon is not
guaranteed to be truly planar, so normal projection may be
a bit off. The code has to use signed angles and checks to
support all possible angular arrangements.
The second issue is very thin and long triangles, which tend
to be very spatially unstable in their thin dimension, resulting
in excess deformation. The code was weighting distance using
the distances between the centroid and the mid-edge points, which
in this case end up as nearly opposite vectors of sizable length
and don't correctly represent how thin the triangle actually is.
It is thus better to use centroid-to-line distances, and an
additional even stricter value for the midpoint that will use
only 3 vertices at evaluation time.

Now the icon's rect are drawn wider than it should be, and with
overlapping, probably in order to compensate for the icon's offsets
inside the rect. The solution is to draw icon's rect of the correct
size and center the icon itself.
And make the hotspot exactly match the icon's rect. The last/right
button's hotspot also covers the extra padding on the right.

Preview icons (e.g. material preview or other data-block previews) use the same
background-job code as deferred loading of custom icons/previews. There was a
check to skip preview generation if the render engine does not support preview

when actually rendering a preview, not when doing deferred loading.
