// The Native App API.

// Implement these functions and you've got a native app. These are called
// from the framework, which exposes the native JNI api which is a bit
// more complicated.

// This is defined in input/input_state.h.

// This might get called multiple times in some implementations, you must be able to handle that.

// before this, although it may be called at any point in time afterwards (on any thread!)
// This functions must NOT call OpenGL. Main thread.

// the rest of the game, so be careful with synchronization.
