/**
* GTKNativeEngine delegates all painting job to native GTK libraries.
*
* Painting with GTKNativeEngine looks like this:
* First, startPainting() is called. It prepares an offscreen buffer of the
* required size.
* Then, any number of paintXXX() methods can be called. They effectively ignore
* the Graphics parameter and draw to the offscreen buffer.
* Finally, finishPainting() should be called. It fills the data buffer passed
* in with the image data.
