There are several techniques for doing spacial anti-aliasing, but the
essential algorithm is to oversample the image and then filter it down to
the resolution of your display device.  For example, if you do four samples
per pixel over a uniform grid and simply average the four values together (a
technique known as box filtering), you will get a crude form of
anti-aliasing.  Improvements can be made by varying the sampling and
filtering techniques (e.g. stochastic sampling, triagular and gaussian
filtering, etc.).  Check any contemporary computer graphics text or look
through recent publications from SIGGRAPH for more details.  

This newsgroup should not be a forum for naive speculation.  There is enough
solid information about the subject that it shouldn't be necessary to shoot
from the hip
