I have added a bunch of tests to the ChannelSelection output code; to
make sure that the RGB channels are non null ... right now "by default"
we are set up to have RGB channels (ie an array of 3 channels exist) but
all the values are null..
I have changed the code to the following:

To repeate the SLDTransformer problem is "patched" for uDig's purposes;
we still have a problem of what the default RasterSymbolizer means ...
it looks like a mistake right now.
