The function for retrieving a shape key by its index is named
somewhat confusingly, and effectively reimplements BLI_findlink.
However, more importantly, for some reason it is coded to return
null for the index 0 instead of the basis shape key. This severely
limits its usability in some cases.
This refactor replaces the function with a simple strongly typed
wrapper around BLI_findlink, using a different name, and updating
the call sites to check that the index is not 0 where necessary.
The old implementation was a simple rounding operation and was not
implemented for full-frame compositor.
The issue with the old implementation is that it will not give
satisfactory results for images with high frequency details,
including cases when is used for a preview on Cycles render with
low number of samples. Additionally, when applied on animated
footage it produces very noisy result.
The new algorithm uses an explicit pixel size setting, which allows
the node to be used on its own, without need to have scale-down and
scale-up nodes. It also uses neighbour averaging, which produces
better looking result during animation and noisy input images.
The old tiled compositor setup will render without changes with
this change. This commit does not include modifications in the GPU
compositor implementation.

Increase performance when drawing scenes that don't have blended materials. This should
save some CPU and GPU cycles as parts (or the whole pipeline) can be skipped.
Mostly it ensures that the hiz isn't tagged dirty and has a chance that it is being reused
by other areas. Shadows and irradiance caches aren't forced to be updated.
Mac Studio M1 Ultra
- space_raceship.blend went from 27 fps to 33 fps (10%-20% improvement).
This is a common scenario to optimize as by default materials are not blended and require
user action to set them up. When using compositing/renderpasses, blended materials aren't
supported and most likely not being used.

An assert that ensures the GPU compositor executes in a non main thread
wrongly fires in background mode, that's because in background mode,
rendering happens in the main thread. So add a condition for background
mode.
When enabling the "Only Show Errors" option in the Dope Sheet/Graph Editor,
it might not show anything even though there are FCurves with errors.
The issue is that the flag `FCURVE_DISABLED` is set by the drawing code,
which means the channels have to be visible first.
This creates a workflow issue where you want to filter down to only the
curves with problems, but you need to find them first...
This PR fixes the issue by validating all FCurves whenever the option
is enabled.

The FPS menu was using a cached value which wasn't being refreshed
when translation changed.
Add `bpy.app.handlers.translation_update_post` handler which runs
when translation changes, this can be used to clear any cached UI
values.

Change the behavior of UI_but_string_info_get to fill in shortcuts
when requested.
Previously shortcuts were ignored for menus, because showing shortcuts
in tool-tips which are already displayed in the menu isn't needed.
Move this logic to tool-tip creation so other the shortcuts may be
accessed in other contexts.
This information can be retrieved from `AssetRepresentation` now.
Also remove unnecessarily specific lambda capture. That usually suggests
usage in `std::function` with a more complex lifetime.
For high radii Kuwahara, we use a Summed Area Table (SAT) implementation
to accelerate the classic variant of the algorithm. The problem is that
due to limited floating point precision, the SAT can produce artifacts
in its output.
An attempt to fix this was implemented in #114191, and while that patch
improved precision by 10x, the artifacts still existed, albeit less
noticeable. But since the improved precision also meant a performance
penalty, it was decided that the improvement is not worth it.
Since the artifacts are only noticeable for scenes with very high
values, this patch adds a High Precision option that defaults to false
and can be enabled by the user upon noticing any artifacts. The option
simply uses direction convolution instead of SAT in this case. The
downside, of course, is that it can be orders of magnitude slower.
An alternative to using this option is for the user to clamp the input
or downsample the image. Both methods should be documented in the
documentation.
Fixes: #113578.

We don't actually protect against interface sockets with empty
names elsewhere. This assert was triggered when trying to group
a `Bake` node, because it tried to create an interface socket of
the extend socket. This case is handled by the check below.
This adds a cache to read a normal vector for a plane that (roughly) fits a curve.
If the curve lies on a plane, the vector always point along this plane normal, otherwise it's an approximation.
The cache is lazily calculated and invalidated when the positions are tagged for a change.
Blender asserts when an Image node is directly connected to a Denoise
node in the GPU compositor. This is because the node reads the image to
host memory, but the cached image didn't specifiy host read usage. This
patch adds the host read usage flag to the IMB module GPU image creation
functions.
The goal is to simplify the interface of the geometry nodes modifier while also
making it more scalable. This allows creating better looking modifiers which
feel more built-in. No functionality is removed by this patch.
The following changes are done:
* The `Output Attributes` panel is hidden when there are no output attributes.
* The `Internal Dependencies` panel is replaced by a new `Manage` panel that
contains all the stuff that is common to all geometry nodes modifiers. It
contains new `Bake` and `Named Attributes` panels for now.
Potential next steps:
* Merge `Output Attributes` panel with the rest of the input list.
* Support hiding the `Manage` panel under some circumstances.

Previously, calling the bake operator was always creating a job that will
be run in parallel to Blender. This is good when baking from the UI, but may
be undesired when baking with a script.
Now, when the `exec` method of the bake operator is called, the baking
happens synchronously. That means that the operator call will return only
after the baking is done. The `invoke` method has the same behavior as
before. This approach is similar to e.g. `FLUID_OT_bake_all`.
I did notice that calling the invoke method from a script can still result
in a crash sometimes, probably due to conflicting depsgraph evaluations.
That has to be investigated more.
The issue was that some code expected the "extend" sockets
to always exist. This was already always true from the user
point of view, but not internally.
There are different possible fixes, but this patch makes sure
that the extend socket will be available as expected. This is
achieved by making them part of the static node declaration.
We want to extend the static declaration of such dynamic
nodes anyway, to improve reflection capabilities without
having to instantiate nodes.
Make Subsampling 3x3 filter twice faster (on 4K UHD resolution,
Windows/VS2022/Ryzen5950X: 52.7ms -> 28.3ms), by reformulating how it works:
Conceptually Subsampling filter is a box filter: it sums up N source image
pixels, computes their average and outputs the result. Critical thing is,
that should be done in premultiplied space so that colors from fully or
mostly transparent regions do not "override" opaque colors.
Previously, when operating on byte images, the code achieved this by always
working on byte values, doing "progressively smaller" lerp into byte color
result, taking care of premultiplication and again storing the "straight"
alpha for each sample being processed. This meant that for each sample, there
are 3 divisions involved! This also led to some precision loss, since for all
9 samples all the intermediate results would only be stored at byte precision.
Reformulate that by simply accumulating the premultiplied color as a float.
This gets rid of all divisions, except the last step when said float needs to
be written back into a byte color.
The unit test results have a tiny difference, since now it is arguably better
(as per above, previously it was having some precision loss).

This allows code outside of the render pipeline to make proper
decisions about how the imbuf of render passes are to be handled.
For example, IMB_create_gpu_texture() will now properly select
single channel grayscale texture format for depth pass coming from
multilayer EXR, additionally solving assert in the GPU compositor
code which verifies expected and actual imbuf texture format.
Pull Request: https://projects.blender.org/blender/blender/pulls/117184
Set the number of planes based on the number of pass channels.
If the pass contains 2 passes or more than 4 passes set the number
of planes to the previously used value of 32.
This is needed because quite some areas check for the number of
planes for various optimizations. For example, this is one of the
factors which make IMB_create_gpu_texture() to choose the texture
format. If the number of planes for the depth pass is set to the
previously used this function will never consider using single
channel GPU texture.
Unfortunately, this change is not enough to make the GPU texture
to use single channel format as the color space of the image
buffer is also checked, and that is nullptr which means scene linear.
Using screen changing functions with screens used for full screen areas
isn't supported & caused corrupt screen data.
Add checks that the current and overriding screen support switching,
raising an error when they don't. Also add a check when restoring the
context not to change any full screen areas.
CurvesGeometry has no ".selection" attribute when all control points
are selected. The earlier code assumed that the attribute always exists.
Also Python tests are added for the "extrude" operator.

There were some abstractions inside `IMB_transform` implementation
that were kinda getting in the way. I want to speed up Subsampled3x3
filtering by reformulating the math being done, but that needs to
sample byte images while storing intermediate result as a float -- but
the whole `Pixel`, `PixelPointer` et al. machinery was not quite prepared
to deal with that. Feels like those helper classes do not achieve much,
just make the code longer.
So remove them (`Pixel`, `PixelPointer`, `ChannelConverter` etc.) and
use simple functions. Now the code is more straightforward (IMHO) and
270 lines shorter (40% of the whole file!), and allows me to do the
follow-up optimization easier.
No functional changes.
