NEW: Replace DebugView’s writeX() functions with renderX() functions.
DebugView writes straight to STDOUT. It would be much more flexible if it returns a string instead. It’s possible that DebugView should be scuttled in favour of a 3rd party library, but in the meantime, this change makes it more useful for the logging changes.
