reduce animation flicker, and cannot know the instant suitable to
display the newly rendered canvas content. When using external
double-buffering via XBufferController on a sprite canvas, the
implementation takes care of this issue, and in this case is able
to render correctly even without explicit updateScreen() calls

can happen, namely the XBufferController::showBuffer()) call. If
you don't need sprite functionality, and don't want the
