Reading an EXR multi-layer image in the compositor is not thread safe.
That's because the code access the render result without holding a
reference to it. To fix this, acquire the render result when accessing
the render result structure.

The Movie Distortion node output is cropped to the bounds of the
original input. This patch fixes that by extending the bounds depending
on how the distortion extends the image bounds.
Cryptomatte meta-data are not loaded from EXR images with unnamed
layers. That's because the code assumed the layer is always named, and
thus had full names with a dot prefix, which didn't match the
Cryptomatte type name. To fix this, only add the dot when the layer is
named.
This patch changes how transformations are realized by adjusting the
computed size of the new domain after transformation. Previously, this
was computed with the lower left corner of the domain as the origin of
transformation, while now, the center of the domain is used as the
origin. Consequently, domains shrinks/grows around their center, which
results in a more stable output as transforms are animated.
A consequence of this change is that we can no longer scale odd sized
domains to even sized domains or vice versa, since it grows/shrinks by
the same amount on both sides. Supporting this case requires further
investigation and will probably require passing down information to the
realization functions themselves.
The outputs of the Image node are missing relevant meta-data like
Cryptomatte and vector components, this causes exports through the File
Output node to also miss those meta-data. To fix this, we populate the
metadata of cached images just like we do for render results.
By now it is just a "compositor", so move the files one folder up.
Things that were under realtime_compositor/intern move into
already existing intern folder.

This patch adds compile-time optimizations where the operation inputs
are guaranteed to be non-single values. Pixel load methods now take an
optional template parameter CouldBeSingle, which is false by default. If
the input is not guaranteed to be single, it needs to be set to true.
Gives up to 3x improvement in some nodes.
The compositor leaks memory when the node tree contains unavailable
links. That's because the compositor doesn't ignore those links when
computing the reference counts for outputs. To fix this, check if the
output is logically linked and return 0 in case it isn't.
This patch optimizes the Distance Dilate code by limiting the search
window to areas within the image, avoiding fallback image sampling and
looping redundant pixels. Gives a 1.8x improvement.
The GPU and new CPU compositors leak memory when an output is connected
to multiple inputs inside the same pixel operation. That's because nodes
do not know that their multiple outgoing links are in fact going to the
same operation, so their initial reference count is more than the actual
reference count.
To fix this, we keep track of the reference count of pixel operation
inputs and release the inputs based on that reference count.
This patch specializes the symmetric separable variable size blur code
for different types. Additionally, now-unused generic type functions
were removed, and unused GPU specialization was removed since they are
no longer free due to CPU support. Gives a 2x improvement.

Move the Gamma Correction pass of blur nodes into its own algorithm to
avoid code duplication and optimize pixel access, since gamma is now
applied for each pixel in the filter window. Gives a 15% improvement.

Optimize pixel access in the new CPU compositor by specializing pixel
load and store for the type of the result that is being loaded or
stored. Gives up to 10% improvement.

The new CPU compositor ignores group inputs that are unlinked. This
patch fixes that by considering all origin sockets in multi-function
procedures, be it an input or an output.
Transform node in the new CPU compositor crash in background mode
because of a call to GPU_max_texture_size where the GPU module is not
initialized. To fix this, restrict this call to GPU device and use 2^16
as an upper limit for CPU.
Implements #130836:
interpolate_*_wrapmode_fl take InterpWrapMode wrap_u and wrap_v arguments.
U and V coordinate axes can have different wrap modes: clamp/extend,
border/zero, wrap/repeat.
Note that this removes inconsistency where cubic interpolation was
returning zero for samples completely outside the image, but all other
functions were not, and the behavior was not matching the function
documentation either.
Use the new functions in the new compositor CPU backend.
Possible performance impact for other places (e.g. VSE): measured on
4K resolution, transformed (scaled and rotated) 4K EXR image:
- Nearest filter: no change,
- Bilinear filter: no change,
- Cubic BSpline filter: slight performance decrease, IMB_transform
19.5 -> 20.7 ms (Ryzen 5950X, VS2022). Feels acceptable.
