@AmigaBlitter

I just added support for tristrip rendering using CompositeTags().

This makes the "lines" program a lot quicker (about 2-4% CPU usage instead of ~15-18%) however also the lines are a bit uglier because there is no anti-aliasing (not sure how to do that with CompositeTags() or if it's possible).

Maybe capehill can help in this, cause he used compositing for SDL2 port.

Compositing is used in blitting and rectangle drawing. SDL has no antialiasing features (texture filtering may be used when blitting).

Do you know if there's a way to use compositing to accelerate antialiasing?

Since drawing lines (without anti-aliasing) is so easy, IMHO it seems more likely that most of your line drawing speed-up comes from the loss of anti-aliasing?
