------- Additional Comments from Oliver Hunt <ojh16 at student.canterbury.ac.nz>
Okay this is the first version of the feDisplacementMap implementation.  Filter
should be correct (per logic + quartz composer) however it's difficult to
validate given test case
(http://www.w3.org/Graphics/SVG/Test/20030813/htmlframe/full-filters-displace-0
1-f.html) fails to render the inputs correctly, let alone the output.  That
said sphere map appears to be doing correct thing on page.
