Commit: Po Lu <luangruo@yahoo.com>

    Simplify box display code on Haiku
    
    * src/haikuterm.c (haiku_calculate_relief_colors): Remove
    `rgbout_c' parameter.
    (haiku_draw_relief_rect): Push state if performing additional
    clipping.
    (haiku_draw_string_box): Stop passing clip rects to the relief
    drawing functions.
    (haiku_draw_glyph_string): Fix calls to haiku_draw_string_box
    for new parameters.
