Static analysis is all very well, but it leads to pointless reports of
non-bugs like this.
resizebox is called only when the referenced stack position is already
known to contain a box (provided that the luaL_Buffer protocol is being
properly followed, which is the responsibility of the caller). As such,
the lua_touserdata call cannot return NULL and there is no bug.
