Detailed Description

Background job to manage requests for deferred loading of previews from the hard drive.

Launches a single job to manage all incoming preview requests. The job is kept running until all preview requests are done loading (or it's otherwise aborted, e.g. by closing Blender).

Note that this will use the OS thumbnail cache, i.e. load a preview from there or add it if not there yet. These two cases may lead to different performance.
