Thumbnail Suggestions

Hi Jules,

I see that the AudioThumbnail class has been modified to be a derivative of a new class titled AudioThumbnailBase. I was wondering if it would be possible to further dilute the concept of the thumbnail in such a way that there could be a generic Thumbnail base class, and the AudioThumbnailBase could derive from such?

Doing so would allow JUCE developers to create MIDI thumbnails, and even video thumbnails.

Perhaps, but would there be much value in having such a generic class? Sometimes when you dilute things down too far, they start to reach homeopathic levels of uselessness!
