Well, I think I *am* rendering into a "buffer" - called KGameCanvas
or QMainWindow or something ... the actual painting occurs long
after my code has stopped executing ...

But then "Thinking is a matter of luck!", as a German friend of
mine used to say ("Denken ist glucksache" (?)).  It sounds rather
paradoxical in English ... :-)

So where does the responsibility for "automatic" buffering stop, in Qt 4,
and we are back to "good old manual buffering" ... :-( ??? ... as in Qt 1?

I fear another major re-write happening ... <exit left, nursing wounds>.

All the best, Ian W.
