Subject: [PATCH] Change the order of the main cameras from NESTED_RENDER to
 POST_RENDER

This seems to be accepted OSG usage for slave cameras. It's possible
that this order is important for rendering instruments that use RTT
textures on systems without frame buffer object support. I'm thinking
that the resulting bugs may be implicated in the "black rectangle" problem.
