        * src/macterm.c (mac_scroll_area): Call CopyBits with local
        coordinates and portBits instead of global coordinates and
        screenBits.  Set fore color and back color to black and white,
        respectively, before calling CopyBits.

        * src/macterm.c (local_to_global_coord): Comment out.
