a lot of people don't get convinced by my "Pseudo-antialiasing " effect and is true is not near the quality of the true effect so :)

Browse Source 
true antialiasing using supersampling:
3 modes implemented:
2x = is a one and a half samples supersampled buffer with a linear texture fetch, this produce a similar result of a 2x MSAA
4x = four samples with a aligned texture fetch in the center of the 4 samples, this produce a little best effect that the first mode.
8x = is a four samples with a  rotated grid fetching producing a nicer (really nicer in some cases) antialiasing.
please test an let me know if you like this :)
i remember to everyone that supersampling is expensive so don't complain in speed drops :)
