Rather than exposing the GLFWwindow that is used, treat it as an implementation detail and use an opaque pointer specific to this library as the context object instead. In practice the use of GLFW can't be entirely internal since the use of GLFW in the library prevents its use by the embedder, but the details of how it is used should not be exposed. This also gives greater control over the API surface, as part of working toward a stable ABI (google#230). This does mean that the embedder cannot manipulate the GLFW window directly, but rather than trust that doing so would be safe across DLL boundaries, any functionality need by the simple embedder use cases this library enables should be exposed via wrappers.

Was that whitespace change deliberately?

I'm not sure what whitespace change you mean, but since we use clang-format the answer is almost certainly yes.
