No, image() returns a reference to the image data loaded by the host app. The 
plugin uses this reference to modify the image (the reference is not const). 
Once the plugin has modified the image, it will notify the host app by 
calling setImageDirty(). The host app implementation of setImageDirty() 
should refresh the image view and consider it as modified, so that it can 
warn the user of unsaved changes if he quits.
