What happens with pathRendering? Does it get inlined with the GpuCommandBuffer
somehow?

Well in Vulkan we never get Path Batches. In GL the command buffers just
immediately forward the calls to the gpu anyways. So I figured this was easier
than having command buffer need to be able to return a PathRendering instance to
send this calls to.
