 GNOME is a project to build a complete, user-friendly desktop based
 entirely on free software.
 .
 A canvas appears as a normal GTK+ widget with its own GDK window (or X
 window).
 .
 The programmer can insert graphical items into the canvas. The canvas
 provides several predefined item types, including lines, rectangles,
 ellipses, polygons, and text. Canvas items can be manipulated after they
 are created and inserted into the canvas. Common operations include
 changing the color of an item or moving it to a different position.
 .
 The canvas takes care of all drawing operations so that it never flickers,
 and so that the user does not have to worry about repainting the items he
 or she wants to display.
