/**
 * GTKEngine delegates all painting job to native GTK libraries.
 *
 * Painting with GTKEngine 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.
