# Prawn supports drawing both lines and curves starting either at the current
# position, or from a specified starting position.
#
# <code>line_to</code> and <code>curve_to</code> set the drawing path from the
# current drawing position to the specified point. The initial drawing position
# can be set with <code>move_to</code>. They are useful when you want to chain
# successive calls because the drawing position will be set to the specified
# point afterwards.
#
# <code>line</code> and <code>curve</code> set the drawing path between the two
# specified points.
#
# Both curve methods define a Bezier curve bounded by two aditional points
# provided as the <code>:bounds</code> param.
