Drawing program your assignment is to write a python program that extends the interactive sketching program that you did for homework problem 4 and 5. this time, however, the program will have additional features that you might find in a commercial drawing program. drawing tool selection is done from a menu of tools displayed along one side of the screen. each tool menu button should include a small "icon" to identify its function. you are free to design these icons as you wish, but they should clearly indicate the tool functions. the following tools should be available: pencil -- pencil line simply draws using the mouse when the left mouse button is depressed. line -- straight line draws a "rubber-band" straight line with starting point at the position where the mouse left button is pressed, and ending point at the current mouse position as long as the button is held down. when the button is released, the line is permanently drawn. box -- outlined rectangle draws an outlined rectangle, with one corner at the position where the mouse left button is pressed, and diagonally opposite corner at the current mouse position as long as the button is held down. when the button is released, the outline of the rectangle is permanently drawn. rectangle -- filled rectangle draws an outlined rectangle, with one corner at the position where the mouse left button is pressed, and diagonally opposite corner at the current mouse position as long as the button is held down. when the button is released, the filled rectangle is permanently drawn. circle -- draws an outlined circle, with its center at the position where the mouse left button is pressed, and its radius determined by the current mouse position as long as the button is held down. when the button is released, the outline of the circle is permanently drawn.
