[Piglit] [PATCH 0/6] Porting MSAA tests to GL 2.1

[Marek Olšák]

Since we now have a GL 2.1 driver with MSAA support - r300g, I had to
port most MSAA tests to GL 2.1, while not affecting the tests that
*really* need GL 3.

I have verified that the expected and reported precision of the
accuracy tests wasn't changed, even though I had to rewrite some GLSL
code from ints to floats. (texelFetch -> texture2DRect; % -> mod)

(re-sending this email with the subject filled in, sorry)
