And thus change of depth buffer scale/offset. Previously, old depth buffers with values that now are out of range could stick around, causing #16941. This clears them to the expected 0 value, which helps Outrun. Ideally we should convert depth buffers to the new format, but if we can get away without that, that's also nice. This is enough for #16941.
