In Prawn, I have the ability to do move_up/move_down/move_left/move_right. I'm just wondering if there's a way to basically do the same thing, but plot a line to that point as you go. Like line_to, just with only needing to specify a relative amount to go.
Now that I'm thinking about it, I could probably make something easily enough on my own. I'm new to Prawn and Ruby, but I think I know enough to be able to build that. Of course, it would be silly to build my own if one exists already...
