Since the initial commit introducing TankItem, there was a connection that replotted the item if the horizontal axis sent the sizeChanged() signal. I never managed to create this signal for the horizontal axis, only for the vertical axes. Therefore remove this thing. If it turns out that we need it after all, readd it in a more deterministic way (i.e. call where it is needed). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
