[Interest] WA_NoSystemBackground vs WA_OpaquePaintEvent

The difference between these two modes is not obvious.

When should we use WA_NoSystemBackground instead of WE_OpaquePaintEvent,
and reciprocally?

When should we use both?

I could not get any clear hint while searching through the Qt source...
