Build Identifier: 

When adding background images in an element usually you use extra pixels in the image to add offsets from the right. That is a waist of data and with gradients this isn't possible.

Reproducible: Always

Steps to Reproduce:
1. Load the attached testcase
2. Look at the extra markup in the code '<div class="right-bg"></div>'. This code is only needed to be able to place the gradients at an offset from the right

Actual Results:  
You need to add extra markup to the html to be able to have backgrounds at en offset from the right.

Expected Results:  
A syntax to express a px or em offset from the right or bottom of the element.
