Subject: [PATCH] Remove un-needed mixin components leaving only FixedToCamera
 (not sure about this one).  Move this.fixedToCamera after the Core.init call
 which creates the underlying core components required.  Add temporary instant
 return from shiftCanvas in case that was being called and contributing to the
 slow-down (probably not).
