John Stachel's fuller explanation of the compatibility of Newton's
emission theory of light and Einstein's relativity:

http://press.princeton.edu/chapters/i6272.html
John Stachel: "As a theory of principle (see above), the theory of
relativity provides important guidelines in the search for such a
satisfactory theory. Einstein anticipated the ultimate construction of
"a complete worldview that is in accord with the principle of
relativity."[25] In the meantime, the theory offered clues to the
construction of such a worldview. One clue concerns the structure of
electromagnetic radiation. Not only is the theory compatible with an
emission theory of radiation, since it implies that the velocity of
light is always the same relative to its source; the theory also
requires that radiation transfer mass between an emitter and an
absorber, reinforcing Einstein's light quantum hypothesis that
radiation manifests a particulate structure under certain
circumstances. He maintained that "the next phase in the development
of theoretical physics will bring us a theory of light, which may be
regarded as a sort of fusion of the undulatory and emission theories
of light."
