[Vv] leaks

[Joël Schaerer]

Hi Arnaud,

I'd argue most of these are not "leaks", but simply objects that aren't
freed before the program finishes (but are still in use until the end).
In my mind a real leak is memory that is lost each time a user closes an
image for example.
Another point is that most of these objects are very very light (a few
kB at most), so it isn't really a problem.

I don't doubt that we have a couple more serious memory leaks (the core
code for vv was written by a rather unexperienced developer :)), but
sorting through the output of vtkDebugLeaks or valgrind is too much work
for a limited benefit.
