It matters only in one place, where POV-Ray calculates the camera
orientation from your location and look_at vectors. It uses the cross
product between vectors to get perpendicular vectors, but it assumes that
the result points a specific way from the vectors operated on; if you're
using a right handed coordinate system instead of a left handed one, this
assumption will be incorrect. The result is that the image will look
mirrored from what you would expect in a right-handed system. You can avoid
this by specifying the direction, up, and right vectors manually, but you'll
have to calculate them yourself.
