CameraNode broken?

There seems to be an issue with the CameraNode draw implementation. This is a screen of the CameraNode draw result for a perspective projection:

This is the actual frustum (own render code):

Also, the CameraNode assumes a perspective projection, so should be reworked to accept any type of frustum matrices.

There are many redundant settings necessary to setup the CameraNode:

• setSize()
• setFarPlane()
• setNearPlane()

The frustum is already fully defined by the view and projection matrix, so these are obsolete.
