 # libgnomecanvas
 
-The GNOME canvas is an engine for structured graphics that offers a rich
-imaging model, high performance rendering, and a powerful, high-level API.
-It offers a choice of two rendering back-ends, one based on Xlib for
-extremely fast display, and another based on Libart, a sophisticated,
-antialiased, alpha-compositing engine. Applications have a choice between
-the Xlib imaging model or a superset of the PostScript imaging model,
-depending on the level of graphic sophistication required.
