image affect the destination graphics image.
The parameter n specifies whether transparency mode is on ( 1) or off (0).
In the transparency mode, white source dots do not change the destination
pixel; in the opaque mode (non-transparency mode), such dots white out the
destination pixel.
Note the similarity to the standard <ESC> *vn N command, but also note that
the opposite meanings of the parameter values. Also, there is no command
corresponding to the standard <ESC> *v n O.

UL index [, gapl, ... gap20 ;]
This command creates line types by specifying gap patterns, which define the
length of spaces and lines comprising a line type.
The index parameter is a clamped integer which can be range 1through 8. If
the index is negative, its absolute value is used.
A maximum of 20 gaps are allowed for each user-defined line type. Gap
values must be non-negative; a gap value of zero produces a dot if specified
for an odd numbered gap that is preceded or followed by a non-zero even-
numbered gap. The sum of the gap parameters must be greater than zero.
