// CLASS:    MDrawRequest
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MDrawRequest)
//
//		This class encapsulates all the information needed to fulfill
//		a request to draw an object or part of an object.
//      This class is used by the draw methods of MPxSurfaceShapeUI
//      derived objects.
//
//      The draw request should be created in the overridden
//      MPxSurfaceShapeUI::getDrawRequests method. Once created the
//      appropriate "set" methods of this class should be used to define
//      what is being requested. Then the request should be placed on the
//      draw reqeust queue using MDrawRequestQueue::add.
//
//      When your request gets processed by maya, your overriden
//      MPxSurfaceShape::draw method will get called with your request.
//      Use the query methods of this class to determine what to draw.
//
//      You create a draw request using the method MDrawInfo::getPrototype.
//      A draw request automatically picks up certain information (listed
//      below) upon it's creation. So you don't have to set any of this
//      information unless you want to change it.
//
//      Information automatically set by MDrawInfo::getPrototype :
//         path                - path to object to be drawn
//         view                - view to draw in
//         matrix              - world matrix for object
//         display appearance  - how object should be drawn
//         display status      - active, dormant etc.
//
//      The draw token is an integer value which you can use to specify
//      what is to be drawn. This is object specific and so you should
//      define an enum with the information you require to decide what
//      is being drawn in your MPxSurfaceShapeUI::draw method.
//
//      Here is an example of draw token values for a polygonal mesh
//      object as defined in an MPxSurfaceShapeUI derived class.
//
//          // Draw Tokens
//          //
//          enum {
//              kDrawVertices, // component token
//              kDrawWireframe,
//              kDrawWireframeOnShaded,
//              kDrawSmoothShaded,
//              kDrawFlatShaded,
//              kLastToken
//          };
