Function getBilinearPoints

getBilinearPoints<T extends Properties = Properties>(
point: VectorPoint,
refData: VectorPoint<T>[],
): BilinearCorners<T>
Sometimes you're given a large swathe of points, and so this function helps find the closest 4 "corners" relative to a pont
Type Parameters
- T extends Properties = Properties
Parameters
- point: VectorPoint
  point to interpolate
- refData: VectorPoint<T>[]
  reference data to interpolate from
Returns BilinearCorners<T>
- the corner points closest to the reference point
