luma and refBlackWhite coefficients (just check they are not NaN for now),
to avoid potential float to int overflows.

f277dbaff0 * libtiff/tif_pixarlog.c: PixarLogDecode(): resync tif_rawcp with 
next_in and tif_rawcc with avail_in at beginning and end of function,
similarly to what is done in LZWDecode(). Likely needed so that it
works properly with latest chnges in tif_read.c in CHUNKY_STRIP_READ_SUPPORT
mode. But untested...
