Purpose

For packed images use unpacking instead of saving as it's much faster.

Technical steps

Added BKE_packedfile_unpack_image instead of cache_image_file for packed images.

Ref: #110765

Thanks.

It should unpack to the same temporary folder where other images are saved for Hydra though. We should not silently overwrite files in the textures/ directory, that could overwrite files that the user does not want modified.

I guess it should use a slightly slower level functiion like BKE_packedfile_unpack_to_file.

The returned string may be null, and if it's not null it needs to be freed.

This file name is not guaranteed to be unique. Maybe put all unpack files in a uniquely name subdirectory?

Something like unpack_%p with the image datablock pointer, similar to how it's done to make cached images unique.

Didn't understand this comment: if we return image filepath, then it will be something like //..\Desktop\Untitled.001.<UDIM>.png.

Sorry, I accidentally submitted this comment after I had changed my mind, ignore it.
