[question] Why Tile has flipFlags?

[tzngit]

tmxlite/tmxlite/src/TileLayer.cpp

Lines 334 to 339 in 4216d0e

	for (const auto& id : IDs)
	{
	destination.emplace_back();
	destination.back().flipFlags = ((id & mask) >> 28);
	destination.back().ID = id & ~mask;
	}

idk why there is a mask and flipflags, and how to use it? I cannot find any description on it from Tiled reference, and how can I set a flip in Tiled Editor?
