[Qt5-feedback] QML/SceneGraph graphics primitives

[gunnar.sletta at nokia.com]

Hi Stefan,

Why don't you just use a QSGPaintedItem which will paint to an offscreen surface using a QPainter. Then you have all the power of the current 2D API at your disposal. 

We are currently not planning on adding any new primitives to QML, we are just improving the ones we have. 

Through the public scene graph API, you can create your own primitives and we have some basic materials (like flat coloring) available. The API is not raw OpenGL, but more low-level than QPainter.
