Output SVG.

This is complicated by two differences with PostScript.

1. The coordinate space of SVG is origin top-left, for PostScript it is origin bottom-left.
2. Clipping in PostScript works by changing the graphics state Clip a path, then all subsequent drawing be rendered only when it is within the clip bounds. Clearly using clipping paths within a gsave ... grestore block is a good idea...

SVG uses tagging. A clipPath element is declared and named then referenced in subsequent elements via the clip-path attribute - clip-path="url(#clip_path_tag)".
