/**
* @class vtkButtonSource
* @brief abstract class for creating various button types
*
* vtkButtonSource is an abstract class that defines an API for creating
* "button-like" objects in VTK. A button is a geometry with a rectangular
* region that can be textured. The button is divided into two regions: the
* texture region and the shoulder region. The points in both regions are
* assigned texture coordinates. The texture region has texture coordinates
* consistent with the image to be placed on it. All points in the shoulder
* regions are assigned a texture coordinate specified by the user. In this
* way the shoulder region can be colored by the texture.
*
* Creating a vtkButtonSource requires specifying its center point.
* (Subclasses have other attributes that must be set to control
* the shape of the button.) You must also specify how to control
* the shape of the texture region; i.e., whether to size the
* texture region proportional to the texture dimensions or whether
* to size the texture region proportional to the button. Also, buttons
* can be created single sided are mirrored to create two-sided buttons.
*
* @sa
* vtkEllipticalButtonSource vtkRectangularButtonSource
*
* @warning
* The button is defined in the x-y plane. Use vtkTransformPolyDataFilter
* or vtkGlyph3D to orient the button in a different direction.
