What do you mean, plugging your own bottlenecks in for speed?
Is your code to render a line on the framebuffer FASTER than
apples?  Re-read it again, I don't think you're doing quite what
you think you are.  Bottleneck plugging is most useful
when you want to examine each individual object - if you then
want this to be rendered, you should proceed to call StdLine, etc.
If you don't want it rendered, you don't need to daisy chain it.
