Mr. Chrisben

Can i cache multiple background, css like this:

background-image: 
  linear-gradient(to bottom, rgba(0,0,0, 0.1), rgba(0,0,0, 0.8)), 
  url(img/bg.jpg);

I believe this would not work, looking at how getBackgroundImageURL is written. I keep this issue opened as enhancement to support such style values.
