SDL_WINDOWEVENT_RESIZED vs SDL_WINDOWEVENT_SIZE_CHANGED

Question

In SDL, what is the difference between these two window events?

SDL_WINDOWEVENT_RESIZED
SDL_WINDOWEVENT_SIZE_CHANGED

In the wiki doc page there is this code sample:

    case SDL_WINDOWEVENT_RESIZED:
        SDL_Log("Window %d resized to %dx%d",
                event->window.windowID, event->window.data1,
                event->window.data2);
        break;
    case SDL_WINDOWEVENT_SIZE_CHANGED:
        SDL_Log("Window %d size changed to %dx%d",
                event->window.windowID, event->window.data1,
                event->window.data2);
        break;

But I don't see the difference.

From the SDL Wiki:

SDL_WINDOWEVENT_RESIZED

window has been resized to data1 x data2; this event is always preceded by SDL_WINDOWEVENT_SIZE_CHANGED

SDL_WINDOWEVENT_SIZE_CHANGED

window size has changed, either as a result of an API call or through the system or user changing the window size; this event is followed by SDL_WINDOWEVENT_RESIZED if the size was changed by an external event, i.e. the user or the window manager
