Volumes are displayed upside down in scenery about scenery

[skalarproduktraum]

I'd resolve this by rescaling Y by -1 in the volume's transform. That'd also keep segmentations etc. aligned correctly.

When testing on RAIExample, doing this in Volume.kt does not resolve the problem (or the equivalent inside Volume.localScale):

        override fun composeModel() {
            @Suppress("SENSELESS_COMPARISON")
            if(position != null && rotation != null && scale != null) {
                model.translation(position)
                model.mul(Matrix4f().set(this.rotation))
                if(volume.origin == Origin.Center) {
                    model.translate(-2.0f, -2.0f, -2.0f)
                }
                model.scale(scale)
                model.scale(volume.localScale())
                model.scale(0f,-1f,0f)
            }
        }

Ok, @skalarproduktraum pointed out that RAIVolume overrides localScale. This is currently the only one that does such an override. Fix is here https://github.com/scenerygraphics/scenery/compare/fix-volume-flip?expand=1

Fixed in #449 👍
