double W.text box(double x 0 , double x 1 , double y, string s, bool draw = true)
formats and writes string s into a box with its left border
at x-coordinate x0, its right border at x1, and its upper
border at y-coordinate y. Some LaTeX-like formatting
commands can be used: \bf, \tt, \rm, \n, \c,
\, . . . returns y-coordinate of lower border of box.
If the optional last parameter draw is set to false no drawing
takes place and only the lower y-coordinate of the box
is computed.
void W.text box(string s) as above with x 0 = W.xmin( ), x 1 = W.xmax( ), and
y = W.ymax( ).
void W.message(string s) displays the message s (each call adds a new line).
void W.del message( ) deletes the text written by all previous message operations.

W.draw node(double x 0 , double y 0 , color c = window :: fgcol)
draws a node at position (x 0 , y 0 ).
W.draw node(const point& p, color c = window :: fgcol)
draws a node at position p.
W.draw filled node(double x 0 , double y 0 , color c = window :: bgcol)
draws a filled node at position (x 0 , y 0 ).
W.draw filled node(const point& p, color c = window :: bgcol)
draws a filled node at position p.
W.draw text node(double x, double y, string s, color c = window :: bgcol)
draws a node with label s at position (x, y).
W.draw text node(const point& p, string s, color c = window :: bgcol)
draws a node with label s at position p.
W.draw int node(double x, double y, int i, color c = window :: bgcol)
draws a node with integer label i at position (x, y).
W.draw int node(const point& p, int i, color c = window :: bgcol)
draws a node with integer label i at position p.
3.4.13 Drawing edges
Edges are drawn as straigth line segments or arrows with a clearance of node width/2 at
each end.
