That's fine, you are free to do so.

Perhaps. The solution is simple: don't set a box-shadow. 

I'd like to retain the functionality, I find it useful.

But the end result is an image with a frozen pixmap shadow at a fixed
resolution and color, forever tied to the border image. I don't want
that. I want box shadows as vectors that are suitable for printing and
DOM manipulations, that compress well. They should be setable
independently of the border image. E.g., it should be easy to change the
box shadow color when when hovering over the element.
