I see. This makes sense. I guess I will have to do a paradigm shift in the
way I think about graphics :). One thing I thought was odd is that the grid
has its own animation. Is it possible to make the animation read from xml? I
mean we could have a default animation, but what if a theme wants to animate
the scrolling differently? Say change the duration of animation or make the
animation bounce (view slightly overshoots the destination and snaps back).

Right, I was trying to wrap Grid in a SelectableGrid that will have a
selector to choose an item.
