Zoom by url

[diegownc]

I implemeted issue #294 with this change you can zoom your draw just updating the url (the parameter is "zoom")

Zoom 60%

Zoom 80%

Error case

Could you make this not mutually exclusive with the load parameter? I'd love to be able to use both for my use case, which is loading in very large images via the load param and needing to zoom out to see the whole thing.

@ajmeese7 Do you want to use both parameters at the same time?

[ajmeese7]

@diegownc yes I do
