Geometry Line Plotting Problem

[Thomas D. Dean]

I am using geometry 3.0.0.  The order of plotting effects 'linestyle' 
property.

== case 1 Failure =====================================================
dx=0.4375/2;
dz=0.31;
dr=1.25/2;
L=0.995;

X = [-L -dz -dz 0 0 -dz -dz -L -L];
Y = [-dr -dr -dx -dx dx dx dr dr -dr];
line(X,Y);

X = [ -L  -L+0.250 -L+0.250 0 ]
Y = [ 0.250  0.250  3/8/2  3/8/2 ]
line(X,Y, 'linestyle','--');
Y = [ -0.250  -0.250  -3/8/2  -3/8/2 ]
line(X,Y, 'linestyle','--');

The line style property is not obeyed.  No dashed line is plotted.  The 
2nd and 3rd calls to line seem to not change the plot.

== case 2 Success =====================================================
dx=0.4375/2;
dz=0.31;
dr=1.25/2;
L=0.995;

X = [ -L  -L+0.250 -L+0.250 0 ]
Y = [ 0.250  0.250  3/8/2  3/8/2 ]
line(X,Y, 'linestyle','--');
Y = [ -0.250  -0.250  -3/8/2  -3/8/2 ]
line(X,Y, 'linestyle','--');
X = [-L -dz -dz 0 0 -dz -dz -L -L];
Y = [-dr -dr -dx -dx dx dx dr dr -dr];
line(X,Y);

The dashed lines are plotted.
