Papyrus 0.6.0 released

Some new features, some drawing improvements and
some bug fixes. The drawing improvements mainly
relate to taking advantage of more aspects of the
cairo API to improve both speed and drawing
quality. Several new controllers are present such
as the Rotator and Scaler controllers that can be
used in combination with a Handlebox for
presenting handles on selections and using the
handles for rotation and scaling. The demo has
been extended to demonstrate the new controllers.
