Incorrect previews for masked Photoshop images in Assets Server

Info: This feature only applies when running Assets Server as a Processing node on MacOS.

When uploading Photoshop images that contain a Channel mask, the preview created by Assets Server can show the first layer mask instead of the actual image.

To correct this, set the following option in the cluster-config.properties.txt file to 'true':

psdProcessingWithIMEnabled=true
