[Interest] Apply shader effect from QtGraphicalEffects to QSGGeometryNode?

[Mark]

Hi,

Back when the graphical effects where first showcased in a blog i was
already kinda scared that there would be no C++ interface to use them
from the C++ side. Now i find myself in the position where i want to
use the DropShadow element from that very same module in custom QML
Scene Graph module and give a line a shadow.

I kinda - very much - dislike copying the relavant parts of the
DropShadow code and re-create that in C++..

Is there a way that i can use DropShadow from the C++ side?

Regards,
Mark
