+bug 7225: Lasagna Larga Doppia Riccia does not plot 0.0
+
+See bookvol8.1, section Lasagna Larga Doppia Riccia
+
+given:
+
+X(i,j) == _
+  if ((8 <= i) and (i <= 42)) _
+   then 5.0/6.0+(5.0*i-40.0)/34.0 _
+   else if (i <= 8) _
+         then 5.0*i/48.0 _
+         else 5.0/6.0*(7+(i-42.0)/8)
+Y(i,j) == j/15.0
+Z(i,j) == _
+  if ((8 <= i) and (i <= 42)) _
+   then 0.0 _
+   else if (i <= 8) _
+         then (8.0-i)/32.0*cos((j+3)*%pi/6) _
+         else 0.25*(i-42)/8.0*cos((j+9)*%pi/6)
+v3d:=draw(surface(X(i,j),Y(i,j),Z(i,j)),i=0..50,j=0..150,_
+           style=="smooth",title=="Lasagna Larga Doppia Riccia")
+colorDef(v3d,yellow(),yellow())
+axes(v3d,"off")
+zoom(v3d,3.0,3.0,3.0)
+
+The middle part of the image should generate 0.0 for the Z value
+but the drawn image does not show a flat plane. Calling Z(30.0,30.0)
+shows that the values of 0.0 is generated.
