Instead of a separate allocation for any arrays in the render node we allocate these as part of the render node itself, using C99 flexible arrays. This leads to less allocations, which is nice, but the major reason for this is that it allows us to change the allocation scheme further in the future. For instance, we want to do stack-like allocation so that all the render-nodes for an entire frame are allocated in one (or a few) chunks.
