hi, all

i posted that nviz2.2 created a wrong RGB image file. i found that the header
was reverse byte order. so i fixed it at least on FreeBSD.

if you get a broken RGB file, check grass/src/libes/libimage/close.c and
change

-----
#else
	if(image->dorev)
#endif
-----

to

-----
#else
	if(!image->dorev)
#endif
-----


Best Regards,
