I am not sure, but LValuePropertyMap might be ok with some proxy type 
(like vector<bool> uses), or not. Also, the doc says LValuePropertyMap is 
required, but the code actually contains a fallback for more general 
property maps, so you could try that.

It may be easier to work with a single point type. If you cannot use 
CGAL's points everywhere, you could instead provide traits that define 
suitable functions for MyPoint.
