FS#527 - Support direct printing of images

We could support direct printing via a *system* printer:

* query system printers
* query supported media sizes & resolutions
* automatically scale/crop as needed? (and handle portrait/landscape automatically)
* submit job via CUPS (or directly to printer backend?)

What I'd like to see in particular is a "print contents of spool" and have the printer spit out a pile of photos.

Progression of methods:

* direct printing using 'lpr -o raw' (requires smarts to deal with gutenprint directly..)
* direct printing using 'lpr image.[jpg|png|whatever]'
* indirect printing using IPP (ideal)

To do this sanely, we'll need to specify a few things like native print sizes and whatnot so we can scale/crop/sharpen/etc appropriately.  As a given printer can support multiple sizes, we're going to need some way of specifying subsets of parameters.

So, to do this:

  • high-level printer/queue name
  • low-level System Printer Queue name
  • Native print resolution (eg 1800x1200) or at least the aspect ratio
  • Fixed list of options to pass to printer (eg media dimensions, quality, etc)
  • Color correction profile?  (Or should we just rely on the OS to do the right thing?)

I have the prototype working, all features but ICC correction.  For sanity, the next step is to split the actual printing off onto a background worker thread not unlike the import workers.

Then figuring out how to work this all into the UI can be tackled.

It's mostly committed now. Still have to figure out what to do about the old "label/brochure" rendering stuff, but one can now print any image directly to any system printer.

Should probably add a mechanism to restrict who can access this.

Access controls implemented, though not on a per-printer basis.  I've also improved the UI a bit, and worked out a bunch of the kinks. 

I'm fairly happy with this thing now.
