Additional lines for added accuracy

[kalamazandy]

When matching to an image that was shot with a wide open f-stop, you'll find issues with accuracy. I'd love to just keep adding more lines so that instead of 2 lines defining the vanishing point, I could add 6 lines and it could take the average of those. It could also help to see which of the lines is the furthest from the others so you know which to tweak/eliminate.

So instead of just a pair of lines for each axes, you might have 8 lines for x, and 4 lines for z.
