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.

If your job/hobby is inventing wheels then you'd damn well better.  How are you producing anything by taking my wheel schematics and aimlessly scribbling over them in crayon?

Back to Visual Basic, please.
