      A rectangle can be drawn by 2 triangles, however, the primitive "#Rectangle" in QtQuick3D has 8 tringles in one. (attached screenshot is captured with nvidia nsight graphics profiler.)

      Minimum qml to reproduce is also attached.

      We should just add #Quad in addition to #Rectangle for this purpose (and perhaps do the same thing with #Cube)
