Line Example

When drawing lines, it may be helpful to use the thumby.display.width and thumby.display.height member variables for the screen width (72), and the height (40). Otherwise, you can do the math yourself. This example uses both methods to draw three different lines:

Bouncing ball
Three lines across the screen horizontally, vertically, and diagonally
