I'm currently working on converting my current tools to the new api but
thats something ill definitely put on my list of things to do.

Ah my bad, I didnt think about people using different resolutions. After
discussing things with bill and caroline I've changed this feature to work
from a starter image instead (jigsaw_3x3.png and jigsaw_5x5.png on the cvs)
and deleted the magic tool. I've got plans for a more "artistic" jigsaw
which will take the form of a magic tool but that might be some way down the
road, so for the time being ive removed the jigsaw magic tool from the cvs
and replaced it with the starter images.
