Bug 1205 - NEWT Security: Clear framebuffer after creation and before visibility (Windows Onscreen)

WindowsWindow.c:
  - WindowUserData.isInCreation set while window at initizalization,
    i.e. before final size/pos/visibility.

    Also no visibility until final NewtWindow_setVisiblePosSize(..) call.
    This is possible since even w/o ShowWindow upfront,
    UpdateInsets(..) is able to gather accurate values.

  - Suppress any Java callback while WindowUserData.isInCreation,
    issue one callback when window is final.
    Use newly accumulated callback WindowImpl.sizePosInsetsFocusVisibleChanged(..)

  - While WindowUserData.isInCreation, WM_PAINT triggers WM_ERASEBKGND
    and WM_ERASEBKGND actually erases background w/ window background color.
