How is anti-aliasing related? I was thinking about rasters: if you don't have many pixels, you need to use every single one the best possible way, so you manually layout every single pixel. If I have a ton, I can draw any vector glyph and I would not need to micro-manage the pixels. Can you elaborate or give me a link?
It takes far less cpu time to draw a bitmap than to draw a vector shape. An in-between solution is to pre-render vector shapes into bitmaps for later use; this is what METAFONT does.
