d0bd02c4ca [libpng12] Fixed off-by-one bug in png_handle_sCAL() when using fixed point 
arithmetic, causing out-of-bounds read in png_set_sCAL() because of failure
to copy the string terminators (Franke Busse).

660178760e [libpng12] Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from 
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
    now that png_ptr->buffer is inaccessible to applications, the special
    handling is no longer useful.
