@brief Compile-time information about OpenGL extensions

Each extension is `struct` named hierarchically by prefix, vendor and
extension name, for example `GL::APPLE::vertex_array_object`. Each struct has
the same public methods as Extension class (requiredVersion(), coreVersion()
and string(), but these structs are better suited for compile-time decisions
rather than Extension instances. See Context::isExtensionSupported() for
example usage.
