                                     Project name: zooming matrix

                                     Descryption: 5x5 matrix that enables zooming using Up arrow, Un-zooming using Down arrow , Rotate right using 

                                     Right arrow, and rotating left using left arrow. To start it click on the canvas, Delete or Backspace cleares the 

                                     screen,Space returns unrotated canvas and 's' or 'S' saves a snapshot ,dragging the mouse moves the matrix with it.
