// In this case I'm not sure. Here I want to remove from the list
// of points those that have been selected by the user. Sounds like a
// job for remove_if. The problem is that FLTK relies on the actual
// object value to draw it. The algorithm remove_if only cleverly copies objects
// inside the list, it does not really remove them as expected. As
// a result, a simple application of remove_if wreaks havoc with FLTK's
// object list. The solution here is to remove the objects from FLTK's group list
// before touching the point list.
// The result is typical STL gobbledygook, and anyway MSVC++ 6.0 can't
// compile it...
