ScrollView - Fix wrapping issue in FixedRuler::GetPageFromPosition

[problem]      Incorrect page would be returned from FixedRuler::GatePageFromPosition when continuously panning right
[cause]        An unwrapped value is passed in since the scrolling never finishes
[solution]     Wrap the value internally before checking position against domain size
