UISlider update events result in compute-intensive apis being called on main thread, causing laggy behavior and occasional crash. #375

In the BuildingLightExample and RasterImageryExample (and their swift counterparts), a UISlider is used to allow the user to play with various effects. This slider however is currently configured to be continuous and as a result invokes it's selector (on main thread) on every update event.

Since the mapbox operations are compute-intensive this causes laggy behavior in simulators (and the occasional crash on Xcode).
