Is the mouse pressed?

Try moving your mouse over the canvas. Do you see the circles follow your mouse? Do you notice how it's hard to draw a picture because the computer never stops drawing circles? Let's fix this by making the program draw circles only if your mouse is pressed!

Draw = function() {

If (----) {

Ellipse(mousex, mousey, 20, 20);

}

}
