[Inkscape-devel] tesselations

Hi to all. Im working in a tesselation code but i dont want to duplicate code, so im trying whith tiled clones. I have this page as reference: http://en.wikipedia.org/wiki/Wallpaper_group#The_seventeen_groups But i think the cloned tiles generated with reset shift, rotation and scale seems wrong. Can any one confirm me if im ok?

Attached are a ex/sample of a tile P3M1.

Regards, Jabier.
