Don't apply transformation fudge when not rotating. 

There is this stupid fudge factor applied to window transformations
when doing a screen rotation animation.  We need this when rotating,
but when not rotating it causes very visible artifacts.  Historically
the non-rotation case only happened due to configuration changes, so
wasn't that big a deal.  Now however that we use this when switching
users, it is more annoying.  So get rid of it for such cases.
