Canvas already has methods for getting / setting of rotation & scale(zoom) of
transformation, only thing missing is translate of transformation.
# new methods
Canvas.transform() -> QTransform
Canvas.setTransform(transform: QTransform)
Canvas.translation() -> float, float
Canvas.setTranslation(x: float, y: float)
# existing rotation & scale methods
Canvas.rotation() -> float
Canvas.setRotation(angle: float)
Canvas.zoomLevel() -> float
Canvas.setZoomLevel(value: float)
# additionally signal for canvas transform change would be really useful.
