I want to draw some anti-aliased lines. But apparently the device doesn't support anti-aliasing at all. Even on primitives. Any ideas on how to do this?

I've tried drawing my own anti-aliased lines pixel by pixel. Works fine in the sim, but a horizontal line of points on the device is buggy. I'll be submitting a bug report on that here. Unless someone else has it working.

why not draw a quad textured with an appropriate texture: http://homepage.mac.com/arekkusu/bugs/in...TexAA.html

This is mentioned in the documentation.

But you should file a bug anyway. A description of why you need AA lines helps.
