Is the metadata["density"] settable?

I haven't used it so I can't say, but given how snapshotting works I'd 
be surprised if it lets us control the pixel density of LC's imaging 
buffer. My hunch is that it's there to inform other programs which may 
be used to display the image. I'd love to be wrong on that.

As of v7 or so you can also export to a variable, which can then be used 
to set the data of an image object without the intermediary file I/O.

Good question. I don't know; I'd always had the impression that tmp is a 
sort of free-for-all where sensitive data is understood to be 
inappropriate.  Maybe modern systems sandbox tmp by app?
