Sorry. Maybe the description is not clear. The issue we raised is to render
into a RGB32F format texture, not RGB32F format renderbuffer.
For the latest OpenGL 4.6 spec, RGB32F internalformat is required by texture,
see Table 8.12 in GL 4.6 spec. So I think it is a missing feature in mesa for
Intel devices.
