* Calculate cost of all conflicts around supertile nsTile0 by adding "star" weight of each tile involved.
* Tile weight can be either from the planes[][] array or from the replacement values in replacement_val_weights
* (when the tiles configuration is not yet committed)
* @param nsTile0 supertile index to process
* @param scaleStartEnd for each conflict triangle add start and end tiles (at the center nsTile0) scaled by this value
* @param conflicts array of calculated conflicts (each is {start_layer, end_layer, direction/type bitmask} or null,
* in that case it will be calculated
* @param replacement_tiles a map of supertile indices to replacement indices (for replacement_neibs and
* replacement_val_weights) or null. If not null, and entry for the supertile full index exists,
* replacement_neibs and replacement_val_weights will be used, otherwise planes[][] data.
* replacement_tiles may be null, in that case planes[][] data will be used unconditionally.
* @param replacement_neibs array of neighbors to use instead of the planes data. First index is an index
* of the replacement supertile (values in the replacement_tiles map), second - layer number and
* the 3-rd one - direction index for 8 connections: N, NE, E...NW. Value is the destination layer
* number. Can be null if not used (when replacement_tiles is null)
* @param replacement_val_weights similar array for tile value/weight data (per-tile index, per layer).
* The innermost data is a tuple {value, weight}
* @param tnSurface TileNeibs instance to navigate through the 2-d array encoded in linescan order
