Before we could give much of a useful answer, we'd have to know a few
more things about your program, such as:

What kinds of lines? (axis-aligned or not? pixel-aligned? pixel width or
wider/thiner? etc.)

Which backend are you targeting (image? xlib? other?)

The easiest way we could comment on whether there's any performance to
be gained is if you could share your program of interest.
