    skins2(Linux and Win): fix transparency issue at window level · a2fa93d5
    Erwan Tulou authored
    When refreshing a window area, the window mask must first be stripped of this
     area, because the new refresh may not result in the same mask being applied.
    
    This patch corrects the following issues :
    - an animated bitmap with transparency varying from one subimage to the next
      is now guaranteed the previous subimage won't leave any trace.
    - a control that becomes invisible now means transparency is restored
     if no other controls exist for the same area (instead of an undefined and visually unpleasant area)
