process parts. This will make it easier to adapt to IPC. The trickiest part here was to make script tasks spawn new layout tasks directly instead of having the pipeline do it for them. The latter approach will not work in multiprocess mode, because layout and script must run in the same address space and the pipeline cannot inject tasks into another process.
