For example, SC.ScrollView uses two properties, horizontalAlign and verticalAlign, while SC.ImageViews uses a single property align:
We should only have one version used for all views.
Edit: It doesn't appear that SC.ScrollView alignment works at all, so it should be fixed too.
SC.ScrollView alignment doesn't work because ScrollView (unexpectedly) does its positioning with scrollTop, which can't be less than zero (req. for centering or bottoming content) on desktop browsers. Why scrollTop?!
