When a thread is destroyed during the atexit() callback cleanup, it cannot
be joined and sits there doing nothing if the CRT is Visual Studio 2012 or
2013. Microsoft has stated that they would not be backporting the fix from
Visual Studio 2015. As a workaround we call ExitThread() forcibly after
the thread exits.

Text objects now support character spacing (as a fraction of the character
width) and text scaling. Also, the alignment enum is now safe.

For some reasons std::thread can’t be joined in Visual Studio 2013. Needs
more investigation but right now it’s Ludum Dare and I don’t have time.

This sort of pImpl inheritance code code was weird, I got rid of it
and added a new pointer in the TileSet class instead.

Lua only supports the "double" type for now, so storing a 64-bit integer
would lose information unless it's encapsulated in a more complex type.
I prefer to disable these accessors for now.
