And at the current state, I learn that libsdl (1.2 and 2) is not thread
friendly, it wants (nah, requires) that the thread that make the display
and pull event to be the MAIN thread (and not another child, even if
alone to make the calls)...

But it's working with libsdl2. As a kludge so far.

Well hidden in libsdl2 forum, the constraint on thread for video and
event (the internal pump is only run by main thread, no pump, no event
to get out).

People spend 3 years in school and think they can program... until they
find a real job and it shows them they do not know yet how to program.

Which C++ ? 03, 11, 14, 17 and I believe 20 is already on the road.
