How to make miniature interactive

[dev-rish]

Firstly, thanks for the great library! I just have a small requirement. Is it possible to to make miniature window respond to the mouse drags. I drags should change the area in focus(in miniature and in the Viewer). I don't have much idea on how how I start implementing customMiniature. May be it could be a little enhancement for the library(considering I haven't missed something in docs). It would be great if I can get some working example or something.
