    menu: Fix touch scrolling on menus close to the monitor edge · bd3ca2b3
    Carlos Garnacho authored
    Specially in the case of comboboxes, those menus could enable scrolling
    even if the contents could fit in the work area, and could show blank
    space in order to line up the selected item with the combobox.
    
    When such thing happens, take into account scroll_offset when relocating
    the menu contents so contents don't jump directly onscreen, and apply
    it so scrolling is allowed in the direction that brings the menu onscreen
    and blocked in the opposite direction.
    
    Also, wait for cancelling the scroll operation until the touch is released
    even if the scrolling arrows disappeared, so the menu item underneath isn't
    selected right away.
