- This CL fixes an old assumption we had about the height of rows in AllApps, and ensures that we account for the difference in height between the predictive icons and the normal icons. - In addition, we refactor FastBitmapDrawable to have multiple states, which it manages in drawing itself, including the press state and fast scroll focus states. And we also refactor some of the fast scroll logic in the all apps recycler view out to its own class. Change-Id: I1988159b2767df733bbbfc7dc601859cde6c9943
