-// Styling for a variable height element with an image background where the
-// middle repeats vertically. You must split your image into three images, and
-// name them with "-top", "-mid" and "-bot" suffixes (right before the file
-// extension.) then pass a filepath as the first argument to this function
-// which does not have a suffix.
-//
-// Example:
-//
-// image files:
-// i/foo-top.png (900x20)
-// i/foo-mid.png (900xwhatever)
-// i/foo-bot.png (900x30)
-//
-// dom layout: <div id="expando"><div><div><div>...</div></div></div></div>
-//
-// Stylus:
-//
-// #expando
-// mangin: 10px auto;
-// width: 900px;
-// background-vertical-stretch("i/foo.png", 20, 30)
-//
-// Notes:
-//
-// You can (optionally) pass 1-4 additional arguments which
-// (effectively) add padding to the inner most div. The default is to
-// have the height and width of the inner div match exactly the outer
-// one. Parameters you specify are relative to that (not the section
-// filled with the "-mid" image).
