    terminal: Allow to place IdeTerminal into GtkScrolledWindow
    
    VteTerminal has 2 flags that need to be flipped for it to be a regular
    GtkScrollable: to make it not try and handle scrolling itself (other than
    with alternate screen), and to use pixels as the scroll unit instead of
    lines. Flip both.
    
    Bump vte to 0.65.90 as these are new.
