This is mostly a stub issue to keep track of progress on improvements to the drag/drop API:

• Dropping lists of files
• Dropping non-file data
  • Dropping multiple types of data at once (i.e. receiving unformatted text and a formatted, HTML version of that text)
  • Potential datatypes to support:
    • Text
    • HTML
    • Image
    • Audio

I did some research into platform-specific clipboard APIs, and as far as I can tell those are the datatypes that we can probably support across all platforms. I'm hesitant to support audio data sine there seems to be way more variance in how platforms support that than the other datatypes, but from what I've seen most platforms expose it in one way or another.
