Attempt to make the isParallelProjection() flag better

match the actual state of the Camera.  When a camera
is created it is initially not a perspective camera and
now will reflect that.  Setting the perspective frustum
will also now clear this flag.
The regular setFrustum can be used for ortho cameras
and so does not change the mode.
