 // New bilerp strategy:
 // Pass through on bilerpList4 and bilerpListFew (analogs to pointList), introduce bilerpEdge
 // which takes 4 points. If the sample spans an edge, then break it into a bilerpEdge. Bilerp
 // span then becomes a normal span except in special cases where an extra Y is given. The bilerp
 // need to stay single point calculations until the tile layer.
 // TODO:
 //  - edge span predicate.
