Use MAKE_ACCESSORS() to generate accessors for all the 16bpp formats

Add support for 16bpp pixels to fetch_and_convert_pixel() and
convert_and_store_pixel(), then use MAKE_ACCESSORS() to generate
accessors for all the 16bpp formats:

    r5g6b5
    b5g6r5
    a1r5g5b5
    x1r5g5b5
    a1b5g5r5
    x1b5g5r5
    a4r4g4b4
    x4r4g4b4
    a4b4g4r4
    x4b4g4r4
