/***
* GeglTileHandler define the chain pattern that allow to stack GeglTileSource classes on
* top of each others, each doing different task in response to command given (see GeglTileSource).
*
* A classical GeglBuffer is a stack of subclasses of GeglTileHandler with a GeglTileBackend on
* the bottom. This architecture is designed to be modular and flexible on purpose, even allowing
* to use a GeglBuffer as a source for another GeglBuffer.
