Fix related to #33480: for blender internal volume rendering, the camera inside
volume wasn't accurate, it still isn't quite but hopefully a bit better by
taking clip start into account.
With clip start it's actually impossible to do a single 'inside' test, since
there will not be a single point where all camera rays start from, though for
small clip start they will be close together.
