Hi Robert.
Even if getView() is overriden by me, I'm still using the _views data
structure, I just need to control the number of views added to the viewer
and their removal.
My internal data structures do not influence _views, just adding more data.
The actual reasons is that I want each view to have its unique number/id,
without it being changed when removing other views.
For example, if I add 2 views, the second one is on index 1. If I remove the
first view, the index changes to 0 (because the _views vector changes) but I
want it to remain 1.
I'm managing the views numbers by myself, using a mapping array for a
"virtual" view number the "actual" view number (its actual position in
_views).
Is there another way to do this?
