Title: Bug fix

I was getting a bug with LineScan when there was a near-vertical line near the right hand edge of the image. After digging down, I saw that some of the `perp_xs` were outside of the image boundaries. It seems to me that the `perp_ys` were being computed incorrectly: shouldn't `y_width` be at a maximum for horizontal lines?
