Thumbnail viewer / navigator?

[andrewboni]

First of all, this is a great library- thanks for the continued development.

I'm wondering if anyone's implemented a thumbnail navigator box (similar to how photoshop and other services do it) like this:

Would be extremely useful to show which area of the svg element(s) are currently being zoomed in on. The navigator could sit in the upper right corner, like how the zoom controls sit in the lower right corner. Thanks!

It should be easy to implement the box and which part of it is zoomed/panned as API exposes these values and their updates.
The more complicated part would be to get the thumbnail of whole SVG. One solution is to simply insert the same SVG one more time into navigator (but it will consume more memory than a thumbnail).

It may also be a nice example for plugin system discussed in #98.

Gently bumping this, since it'd be a great use of the plugin system. I'm drafting up a proof-of-concept, and can post that code here when finished.

If you'll get any working version (even prototype) - you're more then welcome to post it here.

Now there is an example in demos.
