-Self-line crossing when cutting a bend
---------------------------------------
-
-The self-line-crossing may happen after a few bends have been skipped. E.g.
-ends of A<->B cross the line, but "swallow" a few more in between:
-
-     ,______
-    /       \
-    |___A   |    \  \
-        \   |    B\ |             __
-         \  |     | |            /  \
-         /  |     | |___,---,___/A  |
-        /   |     \_________________|
-        \   |
-         \  |    \  \
-         /  /    B\ |     _       __
-    ----/  /      | |    / \     /  \
-   / ,____/       | |___/   \___/A  |
-  / B|            \_________________|
-     |

-If a bend with 180+ deg sum of inflection angles is found, its line between
-inflection angles (AB in our examples) must be crossed with all the other bends
-to detect a possible line-crossing. This is O(N*M), where N is the total number
-of line segments, and M is the number of qualifying bends. It is expensive.
-
-Also, there is another way to remove self-crossing, without removing most of
-the bend. E.g. from:
-
-  \  /
-  B\ |      __
-   | |     /  \
-   | |____/A  |
-   \__________|
-
-Instead of:
-
-  \  /
-   \/ A'
-  B
-
-To:
-
-  \  \_
-  B\   `-,_.__
-   |       A' \
-   |          |
-   \__________|
-
-But perhaps it doesn't look quite as natural. I will trust the original
-article to do the right thing here and remove the bend altogether.
-
-ALSO: the bends should be iterated from different directions:
-
-for i := 0; i < len(bends); i++ {
-  for j := 0; j < i; j++ {
-    ...
-  }
-  for j := len(bends); j > i; j-- {
-    ...
-  }
-}
-
-So if there are multiple bends between the baseline, they will be cut
-correctly.
-
-The Context of a Bend
----------------------
-
-Similar bends:
-
-> For example, if bend 1 has four unit areas and bend 2 has six unit areas, the
-> average size is five units, and the normalized areas of bends 1 and 2 are
-> 4/5=0.8 and 6/5=1.2, respectively.
-
-My comment: everything until this sentence is clear. However, "unit areas" is
-misleading: there is little reason to normalize areas, but leave the distances
-intact (if we'd like to normalize areas, it would make sense to square-root
-them).
-
-Removing that removes changes the meaning of the sentence that **euclidean
-distance** is normalized (the composite of the bend properties), rather than
-a single component.
