// CLASS:    MDrawData
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MDrawData)
//
//    The MDrawData class holds geometry specific information for user
//    defined shapes which maya does not intrinsicly know about.
//
//    This class is used in the draw methods of MPxSurfaceShapeUI
//    For each draw request you must create and add a draw data object
//    which will contain geometry specific information that you will need
//    in the subsequent call to MPxSurfaceShapeUI::draw.
//
//    MDrawData contains one void* member which is a pointer to an
//    object that you define. This object is the geometry needed to draw
//    your shape.
//
//    To create draw data use the function MPxSurfaceShapeUI::getDrawData.
//    This function takes two arguments, the first is a pointer to your
//    geometry object, the second is the draw data being created.
//    To add the data to a request use MDrawRequest::setDrawData.
//
//    Draw data is also used to carry texture information to your draw method.
//    For materials with texture you must call MMaterial::evaluateTexture
//    from your MPxSurfaceShapeUI::getDrawRequests method.
//    Then in your draw method use MMaterial::applyTexture to set up the
//    viewport to draw using the textured material.
