    mesa: Convert colors if span ChanType and renderbuffer data type don't match

    This is a partial revert of f9874fe.  It turns out that the types
    don't always match.  Specifically, this can happen when doing
    glCopyPixels from a float FBO to a RGBA8 FBO.

    NOTE: This is a candidate for the 8.0 branch.
