From 6657a6c53930eb0ff8d03317eb10ea7ddb0c49b4 Mon Sep 17 00:00:00 2001

Subject: Update reordering method names, and make 3d reordering API public

IsContainedVolume -> hasIsolatedZVolume conveys that this affects Z
ordering of views

ProjectToContainedBackground -> ProjectBackwards, since it ended up
using its own projection target, separate from the 3d volume bit
