Remove Point#dump

This is in response to API feedback - dump() methods for most of the
public classes describe complex internal state, which does not fit for
the Point class. Point#dump does not need to exist anyways, because
1. Point#toString exists, and
2. Point#dump only printed out the x,y coordinates, which are already
part of the public api, so printing out a more concise string
representation is trivial.

So, this patch removes Point#dump and just has RemoteAnimationTarget
implement its own print method for Point, since it was the only caller.
