Detailed Description
Applications rendering via QCPainter do not create instances of the painter class themselves, but rather are expected to use a QCPainterFactory. This is relevant only when working with QCPainter without a convenience class such as QCPainterWidget or QQuickCPainterItem, because those provide a QCPainter instance to the application.
All drawing code that operates on the same thread and is using the same QRhi underneath is recommended to share and reuse the same QCPainter, instead of having a dedicated painter (and so factory) in each component. This can be achieved by calling sharedInstance(), instead of constructing a new QCPainterFactory.
