diff view/AlignmentView.h @ 1615:911330a28a7c

Where the "below" view represents only a subset of the "above" view, cut off the feature mappings at the outer edges of the "below" view - don't map everything outside this (it would all just map onto the same single points at beginning and end, which is excessive, confusing and not useful)
