For the anchor mode 'To Cell (resize with cell)' there
were errors e.g. when the cell the object is in does
not scale but move. If that move went further than the
object is, wrong offsets emerged.
Also added full linear per-cell scale instead of only
scale (no translation through scale). Overhauled to
use liner transfomations, too.
