NAME: InitGraph

     USE: Procedure to place the hardware into graphic mode and
          initializes the graphics system. InitGraph accepts
          several parameters.  The first parameter, the graph driver,
          can be auto-detected by substituting the Detect(0) function
          for the graph driver number.  The Second Parameter, the
          graph mode, is the desired graphics mode. The Final parameter
          specifies the path where the driver can be found, with null
          indicating the current directory.  Errors are returned
          through GraphResult.

     DEPENDENCY:  Must first be in graphics mode.  The unit Graph
                  must also be placed in the uses section.

     SYNTAX: InitGraph(Var GraphDriver : Integer; Var GraphMode : Integer;
                            DriverPath : String);
