Done.

I'd love to help, but I don't understand what you mean by a "preloader." Can you explain?

Good point. I wonder how this will work in csstrashman. That site includes ratiocinator as a submodule which heroku pulls in on deploy. Will a submodule inside a submodule work...

After doing some experiments, I have found that the webkit being used in phantomjs does not support pseudo-elements in `window.getMatchedCSSRules()`. The user agent returned from phantomjs is `Mozilla/5.0 (Macintosh; Intel...

Still no fix for this. Here's the internal browser bug https://bugs.webkit.org/show_bug.cgi?id=76736 However I think `window.getComputedStyle` can report psuedo-class styles properly. http://davidwalsh.name/pseudo-element There may be hope yet for this bug.

Thanks for the bug report. Would it suffice for ratiocinator to add `-moz-X`, `-o-X`, and `-ms-X` every time it outputs `-webkit-X`? Maybe enable this feature with an optional command line...

I wonder if the prefix complexities are best solved by putting the output through an existing prefixer like you mentioned. If so which one do you recommend? Would you send...

What's an example for the invalid property bug? Can you create a failing test for that one?

So I ran http://www.csstrashman.com/styles/38305.css through prefixr.com and ended up with https://gist.github.com/begriffs/8391042 . Did this correct the problem?

I hope someone can figure this out. I added a [bounty](https://www.bountysource.com/issues/1374627-all-non-webkit-prefixed-properties-and-values-are-discarded) for this solution of this issue.
