<P><STRONG>Functional Details</STRONG>
<P>
This module creates a set of renderable lines representing the
"connections" component of a specified input.
<TABLE CELLPADDING="3">
<TR VALIGN="TOP"><TD><P><B><TT><STRONG>input</STRONG></TT>
</B></TD><TD><P>specifies the object whose connection elements are to be shown.
</TD></TR></TABLE>
<P><B>Notes: </B><OL COMPACT>
<LI>If the input object lacks a "colors" component, the module adds
a default color to the output.
<LI>Position-dependent color and data components are passed to
the output.
Connection-dependent color and data components are not passed to
the output, because their values along a connection line are
ill defined.
To make the data or colors position-dependent, use the Post module.
</OL>
<P><STRONG>Components</STRONG>
<P>
Creates a new "connections" component and adds a "colors"
component if the input does not already have one.
Connection-dependent components are not propagated to the output;
all other components are.
