Regions are specified as a binary tree of region nodes, and each node must
either be a terminal node or specify one or two child nodes.
Nodes contains two child nodes:
RegionNodeDataTypeAnd = 0x00000001,
RegionNodeDataTypeOr = 0x00000002,
RegionNodeDataTypeXor = 0x00000003,
RegionNodeDataTypeExclude = 0x00000004,
RegionNodeDataTypeComplement = 0x00000005,
Terminal nodes:
RegionNodeDataTypeRect = 0x10000000,
RegionNodeDataTypePath = 0x10000001,
RegionNodeDataTypeEmpty = 0x10000002,
RegionNodeDataTypeInfinite = 0x10000003
RegionNode must contain at least one element.
