We probably should, but I think we're also allowed to just clamp to [0, 1]. It's not immediately clear to me whether a corresponding caps bit exists for this in d3d12.

We already do that, actually. We support enabling depth bounds through D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_DEPTH_STENCIL1, but didn't implement adjusting the min/max values through OMSetDepthBounds() yet.
