Check and update code, graphics for Retina compatibility

[danwood]

I haven't done any kind of audit on this, but we probably want to start making sure that the bitmap graphics in iMedia Browser are retina-display compatible. That means for any bitmap graphics, we have double resolution versions available, and that any scaled image thumbnails should be displayed with the appropriate pixel size on retina displays.

One place this might be tricky is the icons that we pull out of other applications, e.g. iTunes and iPhoto. We'd need to wait for the source applications to be updated with retina graphics before trying to bring them into imedia. (And, if possible, I would rather that we try to use some code to extract the images we need, at run-time, rather than making copies of them and including them in the bundle.)

We can probably add some comments to this issue as we come across specific things that need to be addressed.

Dan, where are we on this?

Mike: I haven't done anything on this, myself. Though I thought I had seen various things go by where you had worked on it. (I guess my comments above are moot given sandboxing issues.) So I don't know where we are at all regarding iMedia and retina graphics.

To my shock and amazement, our code which fishes around inside app bundles for icons still works from within the sandbox. I can only guess Apple have deliberately made app bundles accessible for this sort of reason. Might well go away in 10.9 though!

So I updated our existing code to play nicely with retina icons where available.

Any icons built into iMedia need to be updated though.
