See if it possible to enable NSSupportsAutomaticGraphicsSwitching for Qt Quick 2 applications on Mac

For all MacBook Pros built after early 2011 there is two graphics cards in the machine. One is an integrated one and one is a more powerful one. Apple have made it possible to allow applications to switch to the lower powered one if it does not require anything that is only availalbe in the high powered one. For Qt and Qt Quick 1 apps this already works fine as they do not require anything on the high powered one. However it seems that Qt Quick 2 does.

Since OpenGL 2.0 is available on the integrated one, then it would be great if it was possible to have it switch down to the lower powered one if desired, which means determining which feature Qt Quick 2 uses that causes it to depend on the higher powered card.
