Oh... but the users shouldn't need to delete them right? Hmmm, but do tests on my branch pass for you now after removing them?

SVG seems also problematic because it really is just xml? So probably we should really get serious about the container kind of types.

Well, with ImageMagick you would loose the vector information. Since I have the prejudice that PDF is a pretty complex format, I guess your best bet is to find a...

If I'm not mistaken, arbitrary signatures should be supported in FileIO - just make sure that you accept those signates in your IO library! If FileIO misses to pass down...

I find it bad style to support uppercase and lowercase extensions, which probably only a few extension vendors started doing. So I'm in favor of keeping this explicit for the...

FileIO allows to register multiple libraries for one format. Here are the lines that handle this: https://github.com/JuliaIO/FileIO.jl/blob/master/src/loadsave.jl#L72 As you can see, it tries to load them and the first library...
