A small Lua benchmark including table creation and usage, arithmetics, function calls and upvalues

	print ("Starting Lua ramp bench")
	local startTime = os.clock()
	do
	local floor = math.floor

	local function image_ramp_green(n)
	local img = {}
	local f = 255/(n-1)
	for i=1,n do
	img[i] = { red = 0, green = floor((i-1)*f), blue = 0, alpha = 255 }

A simple way of configuring Lua to accept the indexing of nil values

	static int handleNilIndexing (lua_State* luaState)
	{
	return 0; // zero return values is equivalent to returning nil
	}

	lua_State* setupLua()
	{
	// Create the new lua state
	lua_State* luaState = luaL_newstate();
