Maybe setExposedContentRect() should instead return a bool?

> This makes assumptions about how FrameView does rounding. Maybe setExposedContentRect() should instead return a bool? There is currently no rounding (these were just switched to FloatRect) and it is generally reasonable to expect getters and setters to pair. The setter should probably be renamed if it starts rounding.
