Re: Animating on a layer

Hi Chris,

I think I misunderstood what the problem was, and looking at your code
again, I don't really see a problem with it (I would still call generate
in the timer thread, though).

I'm not sure what the behavior is for the URLRasterLocation is if the
raster isn't loaded. I'd imagine that it should work the same as a
regular location, putting the dot there with its label. Are you saying
that you are getting the dot and label, and when iterate() is called, it
disappears? or not moves?
