In WSpinny, we use QStylePainter to try and paint the WSpinny with the CSS:

QStyleOption option;
option.initFrom(this);
QStylePainter p(this);
...
p.drawPrimitive(QStyle::PE_Widget, option);

Using Qt 5.5.1, the first render of a WSpinny prints:

QMacCGContext:: Unsupported painter devtype type 1

Reading this bug:
https://bugreports.qt.io/browse/QTBUG-32639
it seems this is not supported.

"The bottom line here is that Qt 5 does not support rendering QWidgets with the OpenGL2 paint engine,"

AFAIK we don't actually rely on styling of spinnies currently. Do we?
