I think the main issue is that icons are heavily cached/optimized, and
so the library is being used to render the icons at a particular size
and in particular colors, but not to actually display it on screen.
The icons on screen have been rasterized. Adding animation would
require adding a new icon class (kind of like the pulsing icon class).
That might be doable; I have no idea. The performance probably won't
be great (at least on XOs). We had lots of trouble just rasterizing
all of the static icons in complex views such as the neighborhood
without noticeable performance hits.
