// Important notice:
// This tiling API is created for tiling of complex pipelines with functions which use borders.
// Tiling of pipelines instead of isolated functions can increase scalability of threading or performance of
// non-threaded functions by performing all operations inside CPU cache.
//
// This is advanced tiling method, so you better know what you are doing.
// 1. Pipeline tiling operates in reverse order: from destination to source.
//    a. Use tile size based on final destination image size
//    b. Initialize IwiTile structure with iwiTilePipeline_Init for the last operation
//    c. Initialize IwiTile structure for other operations from last to first with iwiTilePipeline_InitChild
// 2. Derive border size for each operation from its mask size, kernel size or specific border size getter if any
// 3. If you have geometric transform inside pipeline, you need to implement IwiTileTransform interface for IwiTile for this transform operation
// 4. In case of threading don't forget to copy initialized IwiTile structures to local thread or initialize them on
//    per-thread basis. Access to structures is not thread safe!
// 5. Do not exceed maximum tile size specified during initialization. This can lead to buffers overflow!
//
// There is a set of examples covering usage of tiling. Please refer to them for help.
