Make camera recalculate the projection matrix on transformations

[darionco]

Right now the near and far planes are either static or need to to be modified manually, which either cause the graph to go off the far plane and disappear or forces users to set a far plane that is way too far and messes up with rendering depth distances.

A better solution would be to get the camera to modify the near and far rendering distances to always fall within the graph itself, this would result in the best depth rendering while keeping the graph visible at all times.

In the interim, I am using a threshold for the far plane in GraferController
