Statement rectangle parameter

Rectangle parameters specify size and position of a rectangle. They consist of four values that are separated by commas without spaces. The first pair typically determines the position coordinates of the rectangle center, the second pair its width and height. In some instances you may be given the option to change the way values of a rectangle parameter are interpreted. All values may be integer or decimal numbers. As for other numeric parameters, if one require physical units, plain numbers are interpreted as being specified in SI base units (m, s, g). You may append derived units to trigger conversion of the value to SI base units. Allowed derived units are: um, mm, cm, km, in, ug, mg, cg, kg.
