Zoom increase/decrease buttons on either sides of the slider about cropit

Hey @anoopelias, great to hear that cropit is working well for you, and thanks for the proposal! That definitely sounds like a good idea, but one of the principles I have for cropit is that I wanted to keep it minimal, in particular not to have CSS in it, so the user of it can style it from scratch instead of overriding the existing ones. However in my opinion, different people would most likely want to style - and + in different ways, and give them different behaviors (e.g. different zoom steps). Therefore I've exposed simple APIs to get/set zoom, which I suppose you are using, to achieve such functionality, and while it will definitely be useful to some, I would like not to have extraneous options and complex design in cropit. Hope you understand!

@scottcheng While adding - and + I saw there are a few issues to be taken care of, apart from css. Like this for example. However I understand that you don't want to increase complexity in terms of zoom step configuration etc. I also suspected it might be overkill.

Off topic: My cropit based implementation went through QA on mobile devices (Android Chrome/Firefox) yesterday and it worked like a charm. :). Absolutely no change needed.

Good point about the subtleties 👍

Great to hear that it's working well for you! It works on mobile thanks to the kind folks on github :)
