I'm playing with Gilles Tran MakeCloud macro, and the output from tga2df3 didn't
look like a cloud.
After some investigation I found that the TGA output file is confused.
When I use -UA, povray says: makecloud2001.tga, 24 bpp Targa, but the output
file contains an alpha channel (every fourth byte is 0xFF).
When I use +UA, povray says: makecloud2001.tga, 32 bpp with alpha Targa, but
this time I don't have the alpha channel, and tga2df3 generates a cloud.

My povray version is POV-Ray 3.8.0-x.10064738.unofficial, and UberPOV 1.37.1.0
has the same problem.

I couldn't find any mention of this in the newsgroups, but if people are aware
then I apologize for rubbing it in again.

Cheers
Ton.
