There is no point in using the more specialized derived class (QRhiTextureRenderTarget), even though that is what the rt always is. None of the example and test code needs changes since relying on QRhiTextureRenderTarget specifics is very rare in practice (now it will need a static_cast), whereas in the majority of cases the return value is passed on to other functions, for example, beginPass(), that take a QRhiRenderTarget.
