- Remove the degenerate case of vertical directions, by updating the viewup as the camera moves.
- Remove the consequent limitation to 89.9 degrees.
- Add (unused so far) camera roll angle, with setter.
- Add accessors for all angles. Lua will want to know that.
- Rename m_angleV/H to m_viewAngleV/H to distinguish them clearly from the orientation of the mesh. They will differ e.g. when the player is sitting somewhere.
- Rename vertical turn so it includes 'view' in the name, because this one does not affect the player's rotation as turnH does.
- Make player look north at start, like it originally did before the Z-up changes.
