append will-animate css property to scrollable portions of the gallery app.
Created attachment 8341179 [details] [diff] [review] gallery.patch Patch keeps the scrolling portion of the gallery app in one layer. Currently targeting both the thumbnail view and swiping between pictures after touching one image. Video of patch in action: https://www.dropbox.com/s/tfnm37ss1wr9hlk/gallery.mov One potential optimization might be to keep the back button and bottom toolbar from being repainted on each swipe left/right.

I think we should be able to avoid invalidating those without using will-animate. If this is a performance priority we should investigate why.
