I already use WRITE_PNG, after I call TVRD(). I just don't pass WRITE_PNG
the R,G,B parameters, and use the ones in the color table instead.

Do you know of a reason using TVLCT would not work for PNG files, and that
one might be required to call WRITE_PNG with R,G,B explicitly?

I will, however, try this and get back to you.
