   Turned on multiple png_read_update_info in pngvalid transform tests.
   Prevent libpng from overwriting unused bits at the end of the image when
     it is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would
-    overwrite the end of the image if the row width is not an exact multiple
-    of 8 bits and the image is not interlaced.

 Version 1.5.6beta07 [October 21, 2011]
   Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row
