Perhaps a better solution... rather then attempt to override the
camera rotation -
Support regular perspective/ortho views for rendering as we do already
with opengl viewport render.


This poses 2 new problems.

- Need a way to render from a view that isn't easily confused from
rendering from the `real` camera.

- You may want to see the 'frame' in regular viewport...
 (we would then need a way to distinguish camera views from regular
views with a camera frame.. ugh).

Note:
In fact what I said before wasn't right, what you suggest could be
made to work, but every time render/export was done, whoever wanted
the camera transform would need to (optionally) pass in the view-port
so the result taking into account the cursor override could be
calculated. its still fairly impractical (but possible).
