Coorinate Transformation.
| call | DclGrid2DCoordinateTransform | (ux,uy,cx,cy) | 
| ux | <R(:)> | Source Coordinates.(No 1).(Input)  | 
  
| uy | <R(:)> | Source Coordinates.(No 2).(Input) | 
| cx | <R(:,:)> | Destination Coordinates.(No 1).(Output) | 
| cy | <R(:,:)> | Destination Coordinates.(No 2).(Output) | 
(a) If it has not been initialized with G2SCTR, an error occurs.
(b) If inputs out of range of UXA,UYA which is set with G2SCTR, it extrapolates with showing warning.
