  \class SoDrawStyle SoDrawStyle.h Inventor/nodes/SoDrawStyle.h
  \brief The SoDrawStyle class specificies common rendering properties for shapes.
  \ingroup nodes

  Use SoDrawStyle nodes to influence how shape nodes following them in
  the scenegraph will be rendered.  This node type have fields to help
  decide how certain aspects of point-based shapes, line-based shapes
  and filled shape primitives are rendered.

  Simple scenegraph structure usage example:

  \code
  #Inventor V2.1 ascii
  
  Separator {
     Sphere { }
     Translation { translation 4 0 0 }
     DrawStyle { style LINES  lineWidth 2 }
     Sphere { }
     Translation { translation 4 0 0 }
     DrawStyle { style POINTS  pointSize 2 }
     Sphere { }
  }
  \endcode

  </center>

  <b>FILE FORMAT/DEFAULTS:</b>
  \code
    DrawStyle {
        style FILLED
        pointSize 0
        lineWidth 0
        linePattern 0xffff
    }
  \endcode

/*!
  \var SoSFFloat SoDrawStyle::pointSize

  Size in screen pixels of SoPointSet points, and also of geometry
  vertex points if setting the SoDrawStyle::style to
  SoDrawStyle::POINTS.

  The valid range of pointsize settings varies according to which
  OpenGL implementation is used. For the purpose of not trying to set
  illegal values, the application programmer should at run-time check
  the valid range. How this can be accomplished is described in the
  class documentation of SoGLPointSizeElement.

  Default value is 0.0f, which is a "tag" value which tells the
  rendering library to use the default setting.
*/
// FIXME: default value 0? Weird -- shouldn't that mean that no points
// were drawn? Test what SGI Inventor does in that case. 20010823 mortene.

/*!
  \var SoSFFloat SoDrawStyle::lineWidth

  Width in screen pixels of SoLineSet and SoIndexedLineSet lines, and
  also of geometry border lines if setting the SoDrawStyle::style to
  SoDrawStyle::LINES.

  The valid range of linewidth settings varies according to which
  OpenGL implementation is used. For the purpose of not trying to set
  illegal values, the application programmer should at run-time check
  the valid range. How this can be accomplished is described in the
  class documentation of SoGLLineWidthElement.
