Then you are in the wrong thread. Please have a look at the topic before 
posting to the list, and if you see that it doesn't fir what you are writing 
about then change it accordingly. Basic netiquette applies. And don't assume 
that people know what sensor some random camera uses.

Let me make a wild guess: you don't know how linking of executables work? 
Because if you knew you would be aware that libraries can pull in other 
dependencies. And this is what happens here. I admit that I was confused about 
PNG, there is native code for reading and writing, but GIF is definitely not 
possible. As are many others.

Had you read my entire mail you might have seen the part that we do the 
demosaicing in our own code, so it doesn't matter what *Magic can read wrt. 
loading of raw files since that can only pass LDR files to darktable.

I am going through the darktable sources every day and I can promise you that 
you won't find any magic that I am not aware of.

See above, wrong thread for your mail then.
