Zero zoom is possible, crashes script

[perey]

Steps to reproduce

1. Load page.
2. Reduce zoom until it reads zero.
3. Crash.

Firefox specifically reports this error:

A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.

Script: http://hermann.is/gravity/js/gravity/modules/render.js:273

Expected behaviour

Form field does not allow setting zero zoom. Script enforces a minimum value on zoom, or else raises an error if given zero zoom.

Thanks for reporting.
@HermannBjorgvin after my commit with zoom it was fine. Problem should be in the latest commits. Expected behavior does not have to be disabling zero zoom.

Yes, currently working on a new GUI which combines both the render and gui module, should be much smoother and bug free when implemented. Having the seperate gui and render modules was just something I decided on after not sleeping for 24h and has since proven to be a bad idea and prone to frequent bugs
