I've committed the visit() method, but it is still untested.
Do you want to try it out ? If you do examples of use are
in sprite_instance.cpp. One example prematurely ending the loop is
MouseEntityFinder class.
bool operator() (character* ch)
Should be changes with
bool operator() (Range2d<xx>& ch)
You can have multiple overloaded operator() to accept different
kind of Range2d<> classes, or even make the visitor class itself
a template.
