DepthRange enum

What a backend's clip space maps depth onto.

Metal and Vulkan put the near plane at 0 and the far plane at 1. OpenGL puts them at -1 and 1, and WebGL2 has no way to change that — glClipControl is not exposed there.

Not a detail that can be papered over. A projection built for one and fed to the other does not error: with an OpenGL matrix on Metal roughly half the view volume lands behind the near plane and the model looks eaten; the other way round everything still draws, in the correct order, using half the depth buffer — so it costs precision and shows up as z-fighting on surfaces that were fine on the other backend. The second is worse to diagnose, because nothing looks wrong until something does.
