[Feature Request] Grab To Pan

[myleslee]

When a pdf gets scaled up and grows out of the view port, user needs to hold down the mouse to drag it around to see all part of it.

pdf.js offers the feature, is it possible to bake it into vue-pdf?

It could be an interesting feature and shouldn't be hard to develop, but I haven't had enough time to work on this project lately. If you could contribute this It would be great.
