Detailed Description

This helper class can be used for iterating over a voxel array in relation to another one. In particular, dst is the destination voxel array that is to be iterated over; its tile at [X, Y, Z] is taken to be coincident with tile [X + xoff, Y + yoff, Z + zoff] of src. Tiles of dst are partitioned into two sets:

BP (boundary pass): these are tiles of dst that are coincident with tiles of src that are at the boundary (so they affect extrapolation);
IP (internal pass): these tiles are coincident with internal tiles of src (those that are irrelevant for extrapolation). Once created, an object of this class can return the number of tiles in each set and convert from a linear 0-N index to [X, Y, Z] coordinates that identify the tile within dst.

This class can be roughly used as follows... Main function:

__linearTileIndexConverter index(dst, src, xoff, yoff, zoff);
customFunctionBP(..., index);
customFunctionIP(..., index);

BPPartial(..., const __linearTileIndexConverter& index, const UT_JobInfo& i) function:

int t0, t1;
i.divideWork(index.getNTilesBP(), t0, t1);
for (int j = t0; j < t1; j++)
{
    int x, y, z;
    index.toLinearBP(j, x, y, z);
    UT_VoxerTile<T>* dtile = src.getTile(x, y, z);
    ...
}

With a similar implementation for IP. See moveTilesWithOffset() for an example.
