Made views only draw models that are within the viewport.
* Done by sending the gameCamera to all the views, not sure this is the best solution but it does seem to work.
Changed slice views to also use BoundingBox for detecting viewport.
* Using points was buggy on android (possibly due to lag?). using bounding box seems to have fixed this problem, altough this might have a higher performance impact.
