    Max recursion depth error when resizing terminal
    
    When squishing the terminal I can occasionally trigger a maximum recursion
    loop...
    
            Traceback (most recent call last):
                    ...
            File "/home/atagar/Desktop/nyx/nyx/panel/log.py", line 326, in _draw
            self.redraw()
            File "/home/atagar/Desktop/nyx/nyx/panel/__init__.py", line 175, in redraw
            self._last_draw_size = nyx.curses.draw(self._draw, top = self._top, height = self.get_height(), draw_if_resized = draw_dimension)
            File "/home/atagar/Desktop/nyx/nyx/curses.py", line 746, in draw
            func(_Subwindow(subwindow_width, subwindow_height, curses_subwindow))
            File "/home/atagar/Desktop/nyx/nyx/panel/log.py", line 326, in _draw
            self.redraw()
            RuntimeError: maximum recursion depth exceeded in cmp
    
    Adjustments made by the log panel within its draw function *should* prevent a
    need to iterate a second time, but evidently that's not always the case. Simply
    adjusting how we iterate to prevent a forced redraw from triggering another
    forced redraw.
