The initial geometry of a contact is also determined by the geometry management
policy of it parent composite. Just before a composite is realized, the <#2519#><TT>initialize-geometry</TT><#2519#> function is called to negotiate the initial geometry of all
descendants of a composite. This function is called automatically by <#2520#><TT>update-state</TT><#2520#><A ID="2521"><tex2html_anchor_invisible_mark></A>
and rarely needs to be invoked directly by application programmers
or contact programmers. In some cases, a CLUE program may call <#2522#><TT>initialize-geometry</TT><#2522#> in order to complete initial geometry management without
