[PATCH] Implement sin/cos for sphereflake test-suite

[Renato Golin]

  Hi Robert, this is the small output (256x256), the reference output is for the Large problem set. If I run it with the small problem set, I get an identical data as you do (which is encouraging), but my header is not the same:

    $ diff out xcore.out
    1c1
    < P2
    ---
    > 66430 spheres.P2

  You may be redirecting the standard output to it. So, I believe this commit will fix your case, too. After this commit goes through, you can check that the test is generating the correct output and commit the updated md5sum.
