UL - User-defined line type
UL [ i ] [,g [...,]] [;]
i ; unit type g : gap length
 This command allows you to define line types which you can then subsequently select with the LT
command.
 i must be in the range 1-8. i identifies the line type that is to be defined.
 The index parameter uses absolute values.
 g (the gap length) alternately specifies pen up and pen down parts of the defined line type. A maximum of
twenty line sections are permitted, the first of which is a pen down section. Numbers must be integers in
the range 0~32767. These numbers are converted to percentages by the LT command.
 Maximum definition for the gap of each line type is 20. 
 The sum of the gap parameters must be greater than 0.
 Specifying an index number with no gap parameters sets the line type to the default pattern for that index
number.
 Using the command with no parameter sets all line types to the defaults.

WU - Select unit for pen width
WU [ t ] [;]
t ; unit type
 This command specifies the pen width unit. It applies to all pens.
 t must be either 0 or 1.
 If t is 0 the pen width parameter which accompanies subsequent PW commands will be treated as a reading
in millimeters.
 If t is 1 the pen width parameter which accompanies subsequent PW commands will be treated as percentage
of the distance between the scaling points P1 and P2. The default width is 0.1% of the diagonal distance
from P1 to P2.
