Add a command to set global depth bias.
Global depth bias is added to the state specified in shaders (see cull and depth state). This is typically useful when rendering shadow caster objects, to slightly push them away from the light source in order to prevent shadow acne. Built-in shadow caster rendering in Unity sets global depth bias of (1.0, 1.0) when rendering the shadow casters.
