allowing to use it for planar mirrors. Enable it with the new "Plane" option in the Environment Map Panel. Current default is to render the cube side that points to the positive Z axis direction. To make it work, it uses the same image for all other cube sides, so it will 'wrap around'. Also made maximum resolution for environment map to be 4096x4096 now.
