    [WPE][GTK] visible rect in case animations is not correctly calculated
    https://bugs.webkit.org/show_bug.cgi?id=280612

    Reviewed by Miguel Gomez.

    For animations starting partially outside the viewport were not fully rendered when
    the first frame entered the visible area. This caused incomplete or cut-off frames
    during the initial stages of the animation. The issue was more noticeable on low-end
    devices(RPi) or during slow-motion or frame-by-frame analysis of the recordings on x86.

    With this change the visible rect is extended with the elements which are currently
    not fully visible but they will be in a future bacause of animations.
