libgnomecanvas2-dev - 2.30.3-4+b1 main

The canvas widget is a powerful and extensible object-oriented display
engine. A GnomeCanvasItem is a GtkObject representing some element of the
display, such as an image, a rectangle, an ellipse, or some text. You can
refer to this architecture as structured graphics; the canvas lets you deal
with graphics in terms of items, rather than an undifferentiated grid of
pixels.
