Camera Settings

I've been away from SL for a couple of years, and have been dusting off some of my old projects since returning.

I have a "telescope" that sets the camera position when the AV sits so that they can get a view of various stellar images that I have strategically placed. Specifically, it uses :

llSetCameraAtOffet()
llSetCameraEyeOffset()

When I left 2 years ago, these functions worked just fine, but now the camera view doesn't seem to get adjusted when the object is used. Have these functions been obsoleted and no longer work? Should I be using llSetCameraParams() instead?

Furthermore, it looks like PERMISSION_CONTROL_CAMERA has been added since I was last around. Does this work like PERMISSION_TAKE_CONTROLS and PERMISSION_TRIGGER_ANIMATION in that it is automatically granted when the AV is sitting on the object or has it attached?

TIA,
