	* coders/png.c (ReadOnePNGImage): Use libpng function
	png_set_strip_16_to_8() when scaling 16-bit input PNG down to
	8-bit in a Q8 build.  The png_set_scale_16_to_8() function is
	more accurate, but the slight difference causes reference tests
	to fail and causes unexpected difference between the behavior
	of PNG and other formats.  If png_set_strip_16_to_8() is not
	supported in libpng, then we use png_set_scale_16_to_8() if
	that is available.
