// .NAME vtkRectangularButtonSource - create a rectangular button
// .SECTION Description
// vtkRectangularButtonSource creates a rectangular shaped button with
// texture coordinates suitable for application of a texture map. This
// provides a way to make nice looking 3D buttons. The buttons are
// represented as vtkPolyData that includes texture coordinates and
// normals. The button lies in the x-y plane.
//
// To use this class you must define its width, height and length. These
// measurements are all taken with respect to the shoulder of the button.
// The shoulder is defined as follows. Imagine a box sitting on the floor.
// The distance from the floor to the top of the box is the depth; the other
// directions are the length (x-direction) and height (y-direction). In
// this particular widget the box can have a smaller bottom than top. The
// ratio in size between bottom and top is called the box ratio (by
// default=1.0). The ratio of the texture region to the shoulder region
// is the texture ratio. And finally the texture region may be out of plane
// compared to the shoulder. The texture height ratio controls this.
// .SECTION See Also
// vtkButtonSource vtkEllipticalButtonSource
// .SECTION Caveats
// The button is defined in the x-y plane. Use vtkTransformPolyDataFilter
// or vtkGlyph3D to orient the button in a different direction.
