Calculate line lengths when judging if the cursor being positioned is a continuation or a break. for instance the cursor may move to the same y offset but have an x offset which would be way beyond the end of the line as it currently stands. thease should be treated as two seperate objects.

implement the colinear and wobble functions to get this functionality.
