Supported commands

Command         Description
C w h           Should create a new canvas of width w and height h.
L x1 y1 x2 y2   Should create a new line from (x1,y1) to (x2,y2). Currently only
                horizontal or vertical lines are supported. Horizontal and vertical lines
                will be drawn using the 'x' character.
R x1 y1 x2 y2   Should create a new rectangle, whose upper left corner is (x1,y1) and
                lower right corner is (x2,y2). Horizontal and vertical lines will be drawn

                behavior of this is the same as that of the "bucket fill" tool in paint
                programs.
