Returns 0 if the Z clip space range is -1 to 1 and returns 1 if the Z clip space range is 0 to 1. This depends on the renderer curently being used, for example OpenGL uses a clip space range from -1 to 1 whereas Vulkan uses a clip space range from 0 to 1. This only applies to the Z coordinate, both X and Y will always be in the range -1 to 1 in clip space.
