This method actually does the processing of files locally

takes the original file (on remote storages this will be fetched from the remote server) does the IM magic on the local server by creating a temporary typo3temp/ file copies the typo3temp/ file to the processing folder of the target storage removes the typo3temp/ file

The returned array has the following structure: width => 100 height => 200 filePath => /some/path

If filePath isn't set but width and height are the original file is used as ProcessedFile with the returned width and height. This is for example useful for SVG images.
