Actually, for the left side, I wanted to show that the default rendering
does not put the image in the red borders. This has confused a number of
people including the person who coded Inkscape's feImage routines. For
the right side, I hesitated about fitting the image in the red border. I
would have no objections if it changed (the 'y' value would then have to
be changed too to keep the image centered).
