/**
 * Here is an introduction to the most important aspects of the JNA code.
 * 
 * This interface permits access to the Hedgewars frontend library (frontlib)
 * from Java. Each function directly contained in the Frontlib interface
 * represents a mapped C function. The Structure classes (ending in -Struct) are
 * mappings of C structs, and the PointerType classes (ending in -Ptr) represent
 * pointers to structs.
 * 
 * Quick notes for USING these classes from outside this package:
 * 
 * Usage should be fairly straightforward, but there are a few surprising
 * gotchas. First, when you implement callbacks, YOU are responsible for
 * ensuring that the callback objects are not garbage-collected while they might
 * still be called! So make sure you keep them in member variables or similar,
 * because Java will not know if there are still native references to them.
 * 
 * When using Frontlib from outside its package, you only interact with structs
 * via the PointerType classes. They allow you to get at the data of the struct
 * with a function called deref(), which creates a plain normal Java object
 * representing the data (e.g. SchemePtr.deref() will give you a Scheme object).
 * 
 * Remember that you usually have to destroy structs that you receive from the
 * library, because they are owned by the native code, not Java. The recommended
 * pattern for most cases is to call deref() on the pointer to get a Java object
 * (that you can keep as long as you like), and then immediately destroy the
 * struct if it needs destroying. To find out whether and how the struct needs
 * to be destroyed, see the library's documentation of the function that you got
 * the struct from.
 * 
 * To pass new structs to the library, you can use the static createJavaOwned()
 * function in each PointerType, which creates a new struct from the Java object
 * you provide, and returns a pointer to that struct that you can pass to
 * library functions. This new structure's memory is owned and managed by Java
 * code, so do not destroy it with frontlib functions!
 * 
 * There is a slight mismatch between the data model for the game setup. The
 * frontlib supports setting initial health and weaponset per-hog, because the
 * engine allows for that, but currently neither the networking protocol nor the
 * PC frontend support this feature, so the Android version does not take
 * advantage of it either and treats both as per-game settings. The initial
 * health is contained in the game scheme, the weaponset is explicitly part of
 * the GameConfig. When converting GameConfig to a native flib_gamesetup, both
 * are automatically copied to all hogs in the game, and for the reverse
 * conversion the weaponset of the first hog of the first team is used as the
 * GameConfig weaponset. This means that GameConfig.weaponset will be null if
 * there are no teams in the game.
 * 
 * When starting a network game, you only need to query the GameSetupPtr from
 * the netconn and use it to create the gameconn - this is preferable to using
 * your own recreation of the game setup, because that way the same piece of
 * code is used to determine the game setup on all platforms.
 * 
 * The "context" parameter of the callbacks is never needed here because JNA
 * generates function code for each callback object. Don't worry about it, just
 * pass null for context and ignore the context parameter in the callbacks.
 * 
 * Finally, the library functions are documented in the actual library, not
 * here, so check the docs there to find out what exactly each function does!
 * 
 * Notes about the structure of this class (for the next one who has to touch
 * this...):
 * 
 * Java/C interop is quite fiddly and error-prone, so as long as things work,
 * try to stick to the established patterns.
 * 
 * Structure types should always be hidden from the outside world, because they
 * can be misused too easily. For example, if you get a Structure from the
 * library, change a String value in there and pass it back, JNA will re-write
 * that string using Java-owned memory without freeing the old native-owned
 * string, which causes a memory leak and possibly a double-free or other Bad
 * Things (tm). To avoid problems like this, Structure types are only used
 * internally, to map existing structures to Java types (without modifying them)
 * or to create brand-new, Java-owned structures. Both operations are exposed to
 * the outside through the PointerType classes corresponding to the structures
 * in question.
 * 
 * Since all of the struct mapping happens in Java, it is never checked against
 * the actual struct declarations in the library. That means strange things can
 * start happening at runtime if the frontlib structs are modified without
 * changing the mappings here to match. This also applies to the function
 * signatures: JNA checks whether the functions actually exist when loading the
 * library, but it has no way of knowing whether the signatures are correct. If
 * the signatures here deviate from those in the frontlib, you might get stack
 * corruption.
 * 
 * In order to check at least the function signatures, take a look at the file
 * extra/jnacontrol.c in the frontlib sources. You can validate whether the
 * function signatures are still correct by copy-pasting them into jnaControl.c
 * and compiling it against the frontlib headers. The typedefs and #defines in
 * that file will make the compiler see the Java method signatures as C function
 * declarations. Since the same functions are already declared in the frontlib
 * headers, the compiler will give you errors if the signatures don't match.
