    [GTK][WPE] Random incorrect image displayed as the background of a div
    https://bugs.webkit.org/show_bug.cgi?id=265990

    Reviewed by Žan Doberšek.

    Add an unique ID to cairo surfaces created in ImageBackingStoreCairo. This unique ID allows us
    to differentiate when the cairo surface that's backing an image has changed, so we are sure that
    we're not using an incorrect value cached inside some ImageBackingStore.
