Switch from ghostscript's png16m driver to pngalpha for PS->PNG again.

Browse source 
We have switched back and forth quite a few times.  This time I'm switching
because with pngalpha we get gray antialiased text and graphics while with
png16m all we get is no antialiasing.  This is definitely a bug in the png16m
driver, but I won't wait until it gets fixed upstream.

Previously Carl Worth switched to pngalpha and reverted it immediately in
commit c4fc7b06b5.  I've now fixed image-diff to
work with the output of pngalpha, so we can switch.  It requires lots of
reference image updates, but still doesn't help with reducing the number of
PS-specific reference images we need.
