 I just checked the Docs on this and found a clause in the use of the
filter/transmit all function that I never had quite noticed before.
These particular bitmap modifiers only work with .png, .gif, and .iff
image types. It is not supported for .tga image files. It suddenly
clears up some misconceptions I have had for years about the use of
these modifiers.

 Like they say "you learn something new everyday". And with all of
the parameters in Pov-Ray this is a daily occurance.
