        !            23: .SH DESCRIPTION
        !            24: .I Alloc
        !            25: is equivalent to the standard C function
        !            26: .IR calloc ;
        !            27: see
        !            28: .IR malloc (3).
        !            29: It returns a pointer to a block of
        !            30: .I nbytes
        !            31: contiguous bytes of storage, or 0
        !            32: if unavailable.
        !            33: The storage is aligned on 4-byte boundaries
        !            34: and is cleared to zeros.
        !            35: .PP
        !            36: .I Balloc
        !            37: returns a pointer to a Bitmap
        !            38: large enough to contain
        !            39: the Rectangle
        !            40: .IR r ,
        !            41: or 0
        !            42: for failure.
        !            43: The coordinate system inside the Bitmap is set by
        !            44: .IR r :
        !            45: the
        !            46: .B origin
        !            47: and
        !            48: .B corner
        !            49: of the Bitmap are those of
        !            50: .IR r .
        !            51: .I Bfree
        !            52: frees the storage associated with a Bitmap allocated by
        !            53: .IR balloc .
        !            54: .PP
        !            55: .I Gcalloc
        !            56: is also equivalent to the standard C function
        !            57: .IR calloc.
        !            58: It returns a pointer to a block of
        !            59: .I nbytes
        !            60: contiguous bytes of storage, or
        !            61: 0
        !            62: if unavailable.
        !            63: The storage is initialized to zeros.
        !            64: .I Where
        !            65: is a pointer to the user's data where the location of the
        !            66: block is to be saved.
        !            67: The return value of
        !            68: .I gcalloc
        !            69: is stored in
        !            70: .IR *where .
        !            71: .I Gcfree
        !            72: is equivalent to
        !            73: .IR free .
        !            74: .IR p .
