Depends on how the glyph rendering is done. Modern GPU glyph/vector renderers like Pathfinder [1] or Slug [2] keep all the data on the GPU side (although I must admit that I haven't looked too deeply into their implementation details).

That part was about the Amiga blitter specifically. The setup cost for small blits and the relatively low speed of the blitter made it pointless for that specific use.
