[Libpapyrus-users] Papyrus 0.6.0 Released

[Rick L V. Jr <rvi...@cs...>]

Some new features, some drawing improvements and some bug fixes. The 
drawing improvements use more 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. 
This presents handles on selections that can be used for rotation and 
scaling. The demo has been extended to demonstrate the operation of the 
new controllers and also contains example code.
