+Normally, the size of a node is determined by smallest width and height

+See the <A HREF=attrs.html#d:fixedsize><TT>fixedsize</TT></A> attribute
+for ways of restricting the node size.
+In particular, if <tt>fixedsize=shape</tt>, the node's shape will be fixed

+<A HREF=attrs.html#d:height><TT>height</TT></A> attributes, and the shape
+is used for edge termination, but both the shape and label sizes are used
