Details

The way newtab page current displays tiles is that all 3x5 potential tiles are immediately created even if they don't all fit the current window. But if the user resizes the window to be larger, the tiles are immediately available as they were hidden by css overflow hidden.

Potentially we could lazily create the tile and related nodes only when it would be visible. This could help in both animation performance and memory usage as there's less content to try to render then have hidden.
Also a note is that our test machines probably run at high resolutions so they're always going to show 3x5 tiles. We'll probably want tests to make sure it shrinks the window size to see any performance improvement.
