2.4 Coordinate specification
============================

Coordinates are specified within parentheses, with blanks (but no comma)
between the values.  Leading blanks and trailing blanks are permitted
within the parentheses.  The coordinates refer to units, which are
specified by the '\drawdim' command.  The default is inches, but any
valid TeX dimension unit can be specified.  Symbolic specification of
saved coordinate values will be discused later (Note: Saving
positions).

'\drawdim DIM'
     Set the units to DIM.  The argument DIM can be any valid TeX
     dimension unit.  The units are used to interpret coordinate values.
     Examples of valid units: 'cm', 'mm', 'in', 'pt', and 'bp'.

   Examples of coordinate and scaling specifications:
'\drawdim {cm} \move(2 2)'
     Set the units to centimetres, move to a position 2 cm to the right
     and 2 cm up from the origin of the drawing coordinate system.
'\drawdim bp'
     Set the units to big points.
'\lvec ( 2.2 +5.5) \lvec(2.3 -2) \lvec(2.2 5.4 )'
     Examples of acceptable coordinate specifications.
