                int downward, int rightward, TickitPen *pen);

DESCRIPTION

       tickit_window_scroll()  requests  that  the underlying terminal scroll the contents of the
       area corresponding to the visible region (or regions) of the given  window  by  the  given
       amount.  This  takes  into  account  aspects of the visiblity of the window, such as being
       obscured by siblings or siblings of ancestors, child windows, or whether the window or any
       parent  is  hidden.  It  returns  true if it managed to perform the required scrolling, or
       false if not.

       tickit_window_scrollrect() requests that the terminal scroll  the  contents  of  the  area
       corresponding to the given rectangle within the window, and otherwise works analogously to
       tickit_window_scroll(). If the pen argument is non-NULL then it is applied to the terminal
       before  any  erase  operations  within  the  window  are  performed,  allowing a different
       background colour if set.

       tickit_window_scroll_with_children() is similar again, except that it  does  not  consider
       obscuring  regions  by  child  windows;  only  siblings  or siblings of ancestors. This is
       intended for scrolling a container of windows, which will move all of the sub-windows too.
       Note  that  this  function  does not actually move the child windows, it simply requests a
       scrolling operation on the underlying terminal.

RETURN VALUE

       These functions all return a boolean.
