Detailed Description
Controls orthogonal projection matrices, that induce box-shaped visible volume, and base::Camera objects that use such projections.
The base::CameraControl interface delegates rotations and lateral movement to an arbitrary implementation that is supplied to the constructor, but overrides the axial movement s.t. it is realized as zooming through adjustment of the projection matrix.
