* Correct the density (or, rather, remove the density) of
the icons in the cache to ensure they're drawn px-for-px.
* Create a new landscape layout for 2DAA that aligns things
properly (viz: Home icon at right, padding tuned, 6
columns).
* Performance improvement: Make the app grid, icons, and
home icon all opaque (by setting a black background) and
move the home icon so it doesn't overlap the grid.
