Example6_3 - workaround for not drawing on PowerVR Emulator.  Swapping the vertex attributes so that position is attribute 0 and color is attribute 1 fixes the problem.  I suspect this is because it is tricky for the emulator to deal with an app that does not have a vertex array enabled on attribute 0.  It is harmless to the example to make it work there so I'm changing it.
