While I could keep using std::int32_t, as Magnum's Int type maps to it,
I want to be consistent with the rest of Magnum. Also, lots of
whitespace there, but readability is improved.
Debug mode gets outputted to std{out,err}. While most IDEs are sane
enough to capture the streams by default (hello, Qt Creator!), others
aren't (such as CLion, but there's a workaround there), and you can
forget about CMD output as well. Ugh, I hate Windows...
