#16 Show references in graph

[Yann Dirson]

The "call graph" view is a useful tool, but does not
help much when dealing with function pointers. Being
able to show non-call references (namely, assignation
of the function's pointer to a variable) to a function
would be a 1st step towards tracking call-by-pointer.

Next step would probably be being able to follow the
uses/references of pointer-to-function variables and
struct fields, to really track the indirect calls.
