Fixed issue that the decoded image of 8-bit grayscale PNG was broken

  - cause:
    Libpng can trans gray to rgb if png is gray or gray with alpha.
    But decoding png set trans using 'png_set_gray_to_rgb()' if png is only
    grayscale with alpha.

  - solution:
    Set trans gray to rgb using 'png_set_gray_to_rgb' if png is gray or
    gray with alpha. Decoding the png should return only the rgba image,
    so converting rgb to rgba is also added.
