  23
  24     This is the basic interface for 2D graphic primitives. They need to be able
  25     - to provide a decomposition consisting of simpler graphic primitives
  26     - to provide a 2D bound rectangle as a 2D range

  33         2D View-specific parameter set. The defined but not mandatory

  35
  36         ::com::sun::star::geometry::AffineMatrix2D Transformation
  37
  38         A transformation matrix which maps between world coordinates (which
  39         is equal to object's local coordinates) to view coordinates. If not
  40         defined, an empty transformation is implied.
  41
  42         ::com::sun::star::geometry::RealRectangle2D Viewport
  43
  44         Defines the visible part of the view in world coordinates. May be used
  45         to optimize decompositions, e.g. for 3D scenes only the visible part
  46         needs to be created. If not given, an empty Viewport is implied which
  47         means all is visible.
  48
  49         double Time
  50
  51         Defines the point in time for which the geometry is defined. This may
  52         lead to varied results for animated objects. This value is defined in the
  53         range [0.0 .. n[, negative values are not allowed. If not given, a value of
  54         0.0 is implied.
