If true, constraints are generated for each edge in the largest (heuristic)
directed acyclic subgraph such that the edge must point downwards.

<DD> This specifies the expected number of pixels per inch on a display device.

consider using <TT>shape=none</TT> and an HTML-like label.
-<DT><A NAME=ksmoothType><STRONG>smoothType</STRONG></A>
+<DT><A NAME=k:smoothType><STRONG>smoothType</STRONG></A>
<DD>Values are "none", "avg_dist", "graph_dist", "power_dist", "rng",
"spring" and "triangle".
-<DT><A NAME=ksplineType><STRONG>splineType</STRONG></A>
+<DT><A NAME=k:splineType><STRONG>splineType</STRONG></A>
<DD>spline ( ';' spline )*<BR>
<TABLE>
<TR><TD ALIGN=right>where spline<TD>=<TD>(endp)? (startp)? point (triple)+</TR>
goes from p<SUB>1</SUB> to startp. If startp is not given, p<SUB>1</SUB> touches a node.
Similarly for p<SUB>n</SUB> and endp.
-<DT><A NAME=kstartType><STRONG>startType</STRONG></A>
+<DT><A NAME=k:startType><STRONG>startType</STRONG></A>
<DD>has the syntax <TT>[<I>style</I>][<I>seed</I>]</TT>.
<P>
If <I>style</I> is present, it must be one of the strings <TT>"regular"</TT>,
If the value is just <TT>"random"</TT>, a time-based seed is chosen.
<P>
Note that input positions, specified by a node's
- <A HREF=#dpos>pos</A>
+ <A HREF=#d:pos>pos</A>
attribute, are only used when the style is <TT>"random"</TT>.
-<DT><A NAME=kstyle><STRONG>style</STRONG></A>
+<DT><A NAME=k:style><STRONG>style</STRONG></A>
<DD>styleItem ( ',' styleItem )*<BR>
<TABLE>
<TR><TD ALIGN=right>where styleItem<TD>=<TD>name or name'('args')'</TR>
width of the line in <A HREF=#points>points</A>. For example, <TT>style="bold"</TT> is
equivalent to <TT>style="setlinewidth(2)"</TT>.
<B>The use of <TT>setlinewidth</TT> is deprecated; one should use the
- <A HREF=#dpenwidth><TT>penwidth</TT></A> attribute instead.</B>
+ <A HREF=#d:penwidth><TT>penwidth</TT></A> attribute instead.</B>
-<DT><A NAME=kviewPort><STRONG>viewPort</STRONG></A>
+<DT><A NAME=k:viewPort><STRONG>viewPort</STRONG></A>
<DD>"%lf,%lf,%lf,%lf,%lf" or "%lf,%lf,%lf,'%s'"
<P>
The viewPort <TT>W,H,Z,x,y</TT> or <TT>W,H,Z,N</TT>
of a node whose center should used as the focus.
By default, the focus is the center of the graph bounding box, i.e.,
(bbx/2,bby/2), where "bbx,bby" is the
- value of the bounding box attribute <A HREF=#abb>bb</A>.
+ value of the bounding box attribute <A HREF=#a:bb>bb</A>.
<P>
Sample values: <TT>50,50,.5,'2.8 BSD'</T> or <TT>100,100,2,450,300</TT>.
The first will take the 100x100 point square centered on the node <TT>2.8 BSD</TT>
