Visual domain attributes. If the bulge or bezier attributes are present, the bend
should
be rendered as a curve. Otherwise, it should be rendered using lines. The ho and vo
attributes
describe the visual offset of the entire rendered bend. The endho, endvo and startho,
startvo
attribute pairs may be used to encode start and end points relative to their programmatic
placement. For exact placement of the endpoints of the bend, use the x and y
attributes.
