Drawing programs must be able to distinguish which surface is on top anywhere that two surfaces overlap. Existing drawing programs do this by assigning surfaces to distinct layers, so they can't represent interwoven sets of surfaces. Druid uses a more general representation by maintaining local depth ordering of segments of a drawing's surface boundaries rather than a global depth relation between entire surfaces.
