Sub-pixel rendering in assembly

Hi /prog/
Can anyone point out some links where I can find some tutorials for drawing on the screen at the sub-pixel level, preferably in assembly? Googled without much success. Thanks.

>>15 - It's definitely possible....will post here if I find/come up with something.

>>16 - Sure I'm asking for code I can inspect and understand and copy. Is there anything wrong with that? Would you have me reinvent the wheel every time I wanted to get something done? Why the profanity?
