Create rotatable classes

[bj-mcduck]

I'm coming from FontAwesome where there are utility classes for rotating icons, as well as stacking, and animating.

Would it be possible to add some of this functionality? Partly this comes from the same problem as #71.

Being able to rotate the .mdi-action-exit-to-app icon 180º would solve that.
(love the icons btw. really great)

BTW, I don't see a contribution section. Are PRs welcome?

[addyosmani]

PRs are indeed welcome but we should get out a contribution guide soon which helps onboard folks wishing to help. We'll try to get that out soon.

[bj-mcduck]

Super-Awesome, Thanks.

The short version of a contribution guide is to explain that much of this repo is dynamically generated from some of our internal resources at Google. So we'd prefer any pull-requests are additive processes that we can dynamically update any time other assets within the repo update.

[bj-mcduck]

I was with you till the last sentence there...
additive processes? Not sure what you mean by that.

But the next part of the sentence I think I understood.

[jestelle]

What I mean is that any pull request we take in, has to operate in the assumption that all of the assets in the repo may change.

So for example if someone created a different sprite for the PNGs. That'd be great. But we'd also need a script that automates that process, so that when we update all the PNGs, we could regenerate that sprite.

Thus that script is 'additive' in it starts from our initial set of things, and generates some new stuff.

[bj-mcduck]

Oh. Ok. Very good.

I too would love the stacking ability @brandonjmckay mentioned
