// .NAME vtkEllipticalButtonSource - create a ellipsoidal-shaped button
// .SECTION Description
// vtkEllipticalButtonSource creates a ellipsoidal 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 the major and minor axes lengths of an
// ellipsoid (expressed as width (x), height (y) and depth (z)). The button
// has a rectangular mesh region in the center with texture coordinates that
// range smoothly from (0,1). (This flat region is called the texture
// region.) The outer, curved portion of the button (called the shoulder) has
// texture coordinates set to a user specified value (by default (0,0).
// (This results in coloring the button curve the same color as the (s,t)
// location of the texture map.) The resolution in the radial direction, the
// texture region, and the shoulder region must also be set. The button can
// be moved by specifying an origin.
