Make a webpage that contains a canvas element 300*300 with the id of "thisCanvas". Add a button anywhere on the page. When the button is clicked a function will cause a line to appear in the canvas, going from the bottom left corner to the top right. You'll have to make this function. Add a second button. Similarly, when this button is clicked a function should draw a rectangle on the canvas. The position of this rectangle can be defined using canvas.width and canvas.height. Add a third button. This should clear anything that is currently on the canvas using the clearRect() function (this is a library function, you don't have to make it).
