Overzooming and free zoom out

[klokan]

OpenSeaDragon supports free zooming up and down - this was implemented in the original viewer.

Now user can't deep zoom neither zoom out - because the JavaScript implements limit on moving on the image.
On large monitors and with small pictures - it means you can only move the picture to the sides - which is very weird...

Adding:

        minZoomImageRatio: 0.2,
        maxZoomPixelRatio: 5,

or similar to OpenSeaDragon config would improve usability...

The OSD config is in the hawk repository, if I'm not mistaken. I only made the changes that worked for me, anything else is fair game.

I can't oversee the consequences of this, I also don't know where to make the change to test this. Any advise?
