    TextLayout: Clarify implementation of special case
    
    This exists to exit early for invisible lines. It attempts to use the
    LineDisplay’s direction to create a corresponding PangoLayout. However,
    the dir is not yet set by this point, & the display was new0()d, so its
    dir is always 0 == TEXT_DIR_NONE. Thus, we always create an LTR layout.
    
    Whatever the original intent, this outcome seems to be OK, so let’s make
    the code say what it means, rather than using a misleading conditional.
