And here I go again.

I think that I wind up with the color I want to be transparent being
defined more than once in the color map. Due to the way my code is
written, it could wind up setting the transparent color to a later
duplicate instance of the desired transparent color. Then it is no
longer going to be transparent. If I ensure that the transparent color
is defined as the first one, AND that I only set the transparent color
to this index (0), then all is ok. I think that my code wound up setting
the transparent color to the correct color, but the color was a
duplicate at some place other than 0 in the color map.

IMHO, the function gdImageColorTransparent is not fully correct, at
least when making a GIF. The second argument seems to need to be 0.
Anything else results in loff of transparency.
