Draw Route and additional waypoints

[kevinbentley]

The requirements reference rendering the route and the CNPs.

I think we can draw a line from navpoint to navpoint (including those off-screen) to accomplish this.

Here's an idea....

We need to do one of the following:
Draw an arrow telling the user which way to turn when the navpoint is off the screen.
or
Draw the line to where the navpoint would be if it was off screen (picture to come later)

We also need to add support for drawing the next segment in the route (but a different color or somehow less prominent). This should also work if the nav point is off-screen.
