/**
* @class vtkArrowSource
* @brief Appends a cylinder to a cone to form an arrow.
*
* vtkArrowSource was intended to be used as the source for a glyph.
* The shaft base is always at (0,0,0). The arrow tip is always at (1,0,0). If
* "Invert" is true, then the ends are flipped i.e. tip is at (0,0,0) while
* base is at (1, 0, 0).
* The resolution of the cone and shaft can be set and default to 6.
* The radius of the cone and shaft can be set and default to 0.03 and 0.1.
* The length of the tip can also be set, and defaults to 0.35.
