			Renderer is able to process a document and return it as a tree
				of GEF's IFigures.
			Built-in renderers
				There are two built-in renderers:
				- XSL-FO renderer. Able to render XSL-FO XML document using FOP.
- Image renderer, able to render the ImageRef
				     instance. Produces only one IFigure containing whole
				     image, thus it is impossible to modify it in a WYSIWYG fashion.
