Use QPainter from c++

[dridk]

From my personal experience, QPainter is faster than using canvas. Test with animation and scalling...
Do you want add my C++ class instead using pure qml/canvas ?
For exemple the Circle with QPainter::drawCircle..
I don't know if it will fit easily as a library

@dridk Sure that would be great. To add C++ code to this library you can take a look in qml-desktop on how we added QML plugins and also check http://doc.qt.io/qt-5/qtqml-modules-cppplugins.html . QtCreator can also create a plugin project if you create one inside this repo that should be enough to get it working.
