[Interest] Qt3DRender::QBuffer::dataGenerator() deprecated with no explanation?

[Paul Lemire]

Hi Nyall,

 From Qt6 onward, it is expected the data is set directly on the QBuffer 
with QBuffer::setData (For long data processing, we will leave it up to 
the user to create his own thread if needed rather than relying on Qt3D 
executing a functor in its threadpool).

In Qt5.15, the dataFunctor can still be used but not sure the 
deprecation warning can be silenced other than by having the define 
BUILD_QT3D_MODULE set.

Hope that helps,

Paul
