Hello, I have a question about 4 x MSAA with Opengl:

Assume, I draw a white ( 1, 1, 1, 1 ) quad on a black background (0, 0, 0, 1) using 4 x MSAA.
A pixel is covered by the quad by 100% in y direction and by 70% in x direction.
Should the resulting pixel have a color of ( 0.7, 0.7, 0.7, 1 ) ?

Regards
