e7ae9f493a Fix T93310: crash due to broken image paths
The crash was caused by allocating an uninitialized amount of memory.
This fix initializes a bunch of variables that could cause the error.

It should be possible to also fix this in the function that actually uses
the uninitialized memory, but that could cause unknown consequences
that are a bit too risky for 3.0. Just initializing some variables should
be safe though. For more details see D13369.

f84fb12f5d Compositor: Add support for canvas compositing
This commit adds functionality for operations that require pixel
translation or resizing on "Full Frame" mode, allowing to adjust
their canvas. It fixes most cropping issues in translate, scale,
rotate and transform nodes by adjusting their canvas to the result,
instead of the input canvas.

Operations output buffer is still always on (0,0) position for
easier image algorithm implementation, even when the
canvas is not.

Current limitations (will be addressed on bcon2):
- Displayed translation in Viewer node is limited to 6000px.
- When scaling up the canvas size is limited to the
 scene resolution size x 1.5 . From that point it crops.

If none of these limitations are hit, the Viewer node displays
the full input with any translation.

b225a7c470 Compositor: Merge equal operations
Some operations can take a lot of time to execute and
any duplication should be avoided.

This patch implements a compile step that detects
operations with the same type, inputs and parameters that
produce the same result and merge them. Now operations
can generate a hash that represents their output result. They only
need to implement `hash_output_params` and hash any parameter
that affects the output result.

daa7c59e38 Compositor: Full frame Bokeh Blur and Blur nodes
Adds full frame implementation to these nodes operations.

When enabling "extend bounds" node option, tiled implementation
result is slightly different because it's using `TranslateOperation`
with bilinear sampling for centering.
Full frame always uses nearest to don't lose image quality.
It has the disadvantage of causing image jiggling on backdrop
when switching size values as it's not pixel perfect.
This is fixed by rounding to even.

No functional changes.

Part of T88150.

Adds full frame implementation to this node operations.
No functional changes.

Includes a new operation method `init_data` used to initialize any data
needed after operations are linked and resolutions determined.
Once tiled implementation is removed `initExecution` may be renamed
to `init_rendering` and `init_data` to `init_execution`.

fc5be0b598 Compositor: Constant folding
Currently there is no clear way to know if an operation is constant
(i.e. when all rendered pixels have same values). Operations may 
need to get constant input values before rendering to determine 
their resolution or areas of interest. This is the case of scale, rotate
and translate operations. Only "set operations" are  known as 
constant but many more are constant when all their inputs are so.
Such cases can be optimized by only rendering one pixel.

Current solution for tiled implementation is to get first pixel
from input. This works for root execution groups, others
need previous groups to be rendered.

On full frame implementation this is not possible, because buffers
are created on rendering to reduce peak memory and there is
no per pixel calls.

This patch evaluates all operations that are constant into primitive
operations (Value/Vector/Color) before determining resolutions.

b18a214ecb Fix: Compositor test desintegrate failing on arm64
Changes introduced in commit rBe9f2f17e8518
can create different render results when there is
a Math or Mix operation after TextureOperation
on tiled execution model.
This is due to WriteBufferOperation forcing a single pixel
resolution when these operations use a preferred
resolution of 0 to check if their inputs have resolution.
Fixing this behaviour creates different renders too.

This patch keeps previous tiled implementation and
adds the new implementation only for full frame execution.

9adfd278f7 Compositor: Full-frame base system
This patch adds the base code needed to make the full-frame system work for both current tiled/per-pixel implementation of operations and full-frame.

Two execution models:
- Tiled: Current implementation. Renders execution groups in tiles from outputs to input. Not all operations are buffered. Runs the tiled/per-pixel implementation.
- FullFrame: All operations are buffered. Fully renders operations from inputs to outputs. Runs full-frame implementation of operations if available otherwise the current tiled/per-pixel. Creates output buffers on first read and free them as soon as all its readers have finished, reducing peak memory usage of complex/long trees. Operations are multi-threaded but do not run in parallel as Tiled (will be done in another patch).

This should allow us to convert operations to full-frame in small steps with the system already working and solve the problem of high memory usage.

FullFrame breaking changes respect Tiled system, mainly:
- Translate, Rotate, Scale, and Transform take effect immediately instead of next buffered operation.
- Any sampling is always done over inputs instead of last buffered operation.

71cb0bdc43 Fix: File output uses incorrect resolution when first socket unused.
File output node always received the resolution from the first socket.
When that socket didn't had a link it would use a resolution of 0,0.
What lead to not saving the file at all.

This only effected Multi layer OpenEXR files.
This change would go over all the links to find the first valid
resolution.

Surrounding includes with an 'extern "C"' block is not necessary anymore.
Also that made it harder to add any C++ code to some headers, or include headers
that have "optional" C++ code like `MEM_guardedalloc.h`.

I tested compilation on linux and windows (and got help from @LazyDodo).
If this still breaks compilation due to some linker error, the header containing
the symbol in question is probably missing an 'extern "C"' block.
