In release mode our asserts are ignored for performance reasons and all
the code they may be executing is disabled, so no side effects will happen.
We can’t put programming logic in asserts.

Scene rendering logic is now better

The “f” suffix is valid GLSL, but WebGL does not like it so let’s disable it.

Box objects (AABB) now have the long awaited extent() and center()
methods. Corners are now called “aa” and “bb” for convenience. The
WorldEntity class uses a box3 for its AABB instead of two vec3s.
This allows us to simplify a lot of verbose code.

Disallow firing when no ammo is active, tweak laser position, get rid of
the old tileset, add a title screen.

My Ludum Dare 32 entry is now in the main games/ directory and is
called “Size-o-Tron 3000” because… because, that’s all.

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 will be a 2D puzzle platformer. The theme this year is
“Unconventional Weapon”.

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.
