Compute better reference/visual boxes for clip-path in columns

clip-path's are applied before fragmentation, which means that we need
to adjust the coordinate space for the clip-path and its reference box
"manually" to get the correct visual coordinate space.

Also fix the origin used for clip-path to be the top-left corner of the
reference box. This only applies when SVG <clipPath> elements with
clipPathUnits='userSpaceOnUse' is referenced.
