/** \details
The class implements a two-dimensional transformed curve.
A transformed curve is a curve defined by the result of a two-dimensional mathematical function applied to a base curve.
A transfomed curve can be parameterized and transformed for positioning in model space. 
The OdPrcTransformedCurve2d class inherits the <link OdPrcCurve, OdPrcCurve> class and can be reparameterized and trimmed using the <link OdPrcParameterization, OdPrcParameterization> class 
and the <link OdPrcCurve::setParameterization@const_OdPrcParameterization&, setParameterization()> method of the <link OdPrcCurve, OdPrcCurve> class. 

\remarks
Transformation can be one of the following:
  <table>
    <tr><th>Value</th><th>Description</th></tr>
    <tr><td>0x00</td><td>Identity</td></tr>
    <tr><td>0x01</td><td>Translate</td></tr>
    <tr><td>0x02</td><td>Rotate</td></tr>
    <tr><td>0x08</td><td>Scale</td></tr>
  </table>
