 /*
 A scss mixin that convert background images from original URL path to DataURI with IE6-8 fallback.

 - Based on `compass/css3/images`
 - Support 1-10 background image(s) as arguments of `background-image` in compass.
 - Use class `lt-ie9` in `<html>` tag as `html5-boilerplate` to determine if current browser is IE6-8 or not.
 - Image created by `linear-gradient` will be skipped.

 # Example

  @import "datauri-bg";

  div {
    @include datauri-bg("sample.png"); // single background
    @include datauri-bg("sample1.png", "sample2.png", "sample3.png"); // multiple backgrounds
