Should we join this line with the line below?  It looks like some of these are
duplicated.

[Theresa, 2015/10/24 00:06:44]

They're duplicated because there's a different lint warning produced for each
density that's missing a certain image(s); I don't remember exactly why I had to
duplicate the lines.. currently it's not needed because the crushed sprite is in
every density but I'll drop some of the densities before landing. I'll try to
make the regexp smarter (make the expected inclusion of "
google_icon_sprite.png," 0-1 rather than creating a completely separate list).

I added a TODO note for myself (that will be done before the CL is landed). I
also still need to figure out which resolutions we need to keep and which ones
we can cut and still have the animation look good on various devices.
