plemented almost entirely in the GenView object; some content objects, however, will want to react in a special way when the scale factor is changed. The scale factor is stored in a <CODE>
PointWWFixed</CODE>
 structure, as follows:</DD>
<PRE>typedef struct {
    WWFixed    PF_x;   /* horizontal scale factor */
    WWFixed    PF_y;   /* vertical scale factor */
} PointWWFixed;</PRE>
<DT>
</DT><DD>The <CODE>
WWFixed</CODE>
 structures that determine the scale factor in each dimension consist of two elements.
