Crop-Scaled images have wrong file content type
File Abstraction Layer (FAL)
The following scenario is given:
- resize a 300dpi TIFF image to PNG using stdWrap/cObj
- the 'fileExtension' configuration is not set ($fileArray['ext'] is empty)
- the processed file csm_... has the file extension PNG
- but the file content type is still TIFF, so the file was just renamed, but not converted to PNG
Since the processing task determines the accordant filename and file extension, the image processor (ImageMagick, ...) needs to know about that fact as well.
