#176 Extrusions along X axis rotated incorrectly

John Stewart

In v1.18.3 Extrusions with a spine along the X axis
have their
cross-sections rotated incorrectly. Extrusions
extruded along the Y and
Z axis are fine.

The attched .wrl contains three Extrusion nodes.

All three have the same cross section, an isoceles
triangle (so it is clear which way it is pointing).
crossSection [ 1 1, 0 -2, -1 1, 1 1 ]

The spines are along each of the three axes, Y (top) ,
X (middle), Z(bottom), starting at 0 0 0, and ending 4
units along the respective axis.

The triangle of the middle extrusion (along the X
axis: spine [ 0 0 0, 4 0 0 ]) should be 'pointing'
towards the negative Z axis as in the second image
(attached), not along the positive Y axis as v1.18.3

My understanding of the extrusion node (based on http:/
nodesRef.html#Extrusion) is that the middle extrusion
should look like the extruison in Y (top extrusion),
rotated 90 degrees about the Z axis.
