called when widget is shown from resizeEvent() called when widget
is hidden!
It really matters when you re-render complex svg on each resize and
when resizeEvent() comes from some Qt internal magic (layouting etc).
Why re-render if widget isn't visible and this resizeEvent() for sure
won't be last in sequence?

Now I know the True (tm)

Many thanks to aseigo & JohnFlux :-)

You just need to check what
QWidget::testAttribute( Qt::WA_PendingResizeEvent ) returns.

If this is false, then paint! :-)

One step further on the way to faster startup times.

Hmm... Or am I only one who just discovered this? ;-)
