since its implementation is currently rather marginal. It may
even be that this coder deserves to be marked with the new
BrokenCoderClass. We are still looking for a volunteer to iron
out the wrinkles in the PSD reader.</li>
<li>magick/magick.h (CoderClass): Added BrokenCoderClass to mark
coders which often malfunction or are not very useful in their
current condition. Sometimes there is still hope that problems
will be resolved and so the source file is not outright deleted.
This setting allows us to mark and use coders which might
malfunction by defining MAGICK_CODER_STABILITY=BROKEN in the
environment while not causing danger for normal use.</li>

png_set_strip_16_to_8() when scaling 16-bit input PNG down to

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.</li>
