What i mean by reimplementing a QGraphicsView and QGraphicsScene is that
we could look into Extending the given Qt framework classes that
usually deal with this sort of stuff giving us a whole load more
functionality without too much fuss. The only real problem to overcome
would be the Subclassing of the QGraphicsView as we would have to
consider the spherical rendering and correct accordingly. Alternativly
the mapping could be done at at the QGraphics Scene level but this would
mean that each QGraphicsItem would have to maintain its coordinates in
both the spherical and the flat ( rectangular ) projections. Either way
the use of the QGraphics Library could be really helpful.
