[vtkusers] Need Help with vtkPlaneSource Sizing

[John Biddiscombe]

Use
SetOrigin(0.0, 0.0, 0.0)
SetPoint1(10.0, 0.0, 0.0 );
SetPoint2(0.0, 34.0, 0.0 );

and then
SetXResolution(10);
SetYResolution(340);

and you'll get a plane with 10x340 quadrilaterals with dimensions 1.0x0.1

When you change the resolution, you change the number of quadrilaterals, but
the area covered is still controlled by point1,point2 and origin
