 * Purpose: Facilitates creation and maintenance of a RISC programs

 *   dwBufPitch_: DWORD - buffer pitch
 *   Field_: VideoField - which field the program is for
 *   Interrupting_: bool
 *   ProgramSpace_: PsPageBlock * - pointer to the class that manages the memory
 *   occupied by a program ( allocates, deallocates, obtains information )
 *   BufFormat_: ColorSpace - format of the data in the buffer
 * Operations:
 *   void  ChangeAddress( DWORD dwNewAddr )
 *   void  SetClipping( LPRECT pRect )
 *   void  Create( bool NeedInterrupt )
 *   void  SetChain( DWORD dwProgAddr )
