This really needs a qualifier: NSImage *can* create hidden windows to
manage resources. To be more specific, NSImage can create an
NSCachedImageRep, which in turn creates NSWindows. The specific
circumstances in which this happens are when you draw into an NSImage
using lockFocus and the like, and at least sometimes when you draw
with the image. Simply creating an NSImage from a file and then
extracting one of its representations shouldn't create an
NSCachedImageRep.
