Point parameters specify coordinates of a point. They consist of two
coordinate values that are separated by commas without spaces. The values
specify integer or decimal numbers. As for other numeric parameters,
if coordinates 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.
Examples:
Center=255,0
Goal=1.523m,123.4cm Goal=1.523,1.234
