//  ========== DtCameraGetMatrix ==========
//
//  SYNOPSIS
//	Return the camera transformation matrix. This matrix
// 	includes the camera rotation, translation, and scale
//	transforms. This function also sets the valid bits
//	for DT_CAMERA_POSITION and DT_CAMERA_ORIENTATION.
//	The matrix is in row-major order.
//
//  From PA DT:
//          Not implemented: returns a pointer to an identity matrix
//          under the OpenModel implementation.
//
//  For Maya DT:
//          This fuction returns the camera's global transformation matrix.
