You can use negative numbers if you want to start printing relative to the bottom-right corner, but this behavior may change in future versions. `width` and `height` determine the size of the frame. `title` is a Unicode string. If `clear` is True than the region inside of the frame will be cleared. `fg` and `bg` are the foreground text color and background tile color respectfully. This is a 3-item tuple with (r, g, b) color values from 0 to 255. These parameters can also be set to `None` to leave the colors unchanged. `bg_blend` is the blend type used by libtcod. .. versionadded:: 8.5 .. versionchanged:: 9.0 `fg` and `bg` now default to `None` instead of white-on-black.
