[RQt-devel] recent smoke update

[Michael Lawrence]

Well, the paper was a little tough for me to grok. But anyway, I think we
need a consistent type conversion policy. When Qt always treats a class as a
pointer (e.g. QObjects), it's pretty clear that we need to do the same. For
value types, it's more complicated. Qt uses values to avoid the
complications of memory management (as with QImage) or to avoid memory
allocation overhead for small types (like QPen).
