-----------
spherical panoramic fix
note: this was never correct and not a single soul bothered noticing that.
not really a surprise, this mode is more for debug than for anything else.
to test go to (game engine) Render -> Dome Mode -> Spherical Panorama

thanks to Aldo Zang to help me spotting the problem.
