Emitted when the position of window is finalized after being moved to a destination rectangle.
window might be flipped over the destination rectangle in order to keep it on-screen, in which case flipped_x
and flipped_y will be set to true accordingly.
flipped_rect is the ideal position of window after any possible flipping, but before any possible sliding.
final_rect is flipped_rect, but possibly translated in the case that flipping is still ineffective in keeping
window on-screen.
