any shape made from commands
objectbox shape (one box, one inlet, one outlet)
4-element grid describing bounding box (bbox) of text
scale factor. this is the amount of padding around the text. the inlet and outlet is 2 such units high and 7 such units wide. The total height of the box is thus 6*scale plus the height of the bbox. The width is 2*scale plus the width of the bbox. If the bbox is too small, it will NOT be padded to make room for the inlet and outlet.
