Chris Craik 6657a6c539 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
