Class implements a two-dimensional circle with its possible parameterization and transformation for positioning in model space. 
\remarks
Transformation can be one of the following:
  <table>
    Value  Description
    0x00  Identity
    0x01  Translate
    0x02  Rotate
    0x08  Scale
  </table>

  OdPrcCircle2d inherits the OdPrcCurve class and can be reparameterized and trimmed using the OdPrcParameterization class and setParameterization() method.
