<code>trapezoids</code>

Draws a set of anti-aliased trapezoids. The trapezoids are
combined using saturation addition, then drawn over the background
as a set. This is low level functionality used internally to implement
rotated underlines and backgrouds when rendering a PangoLayout and is
likely not useful for applications.
