[cairo] X extensions

[Russell Shaw]

Hi,
I want to add tiltable ellipses, bezier curves, and other graphic primitives as
an X extension. I already have code for them that works. Is there an active
developers list for X hacking?

Does cairo replace the X graphics primitives for drawing lines and circles etc?
Is cairo used for text, or is there another api for that?

What headers do i need to use cairo? Does cairo have extra Xlib commands?
I'm programming in Xlib directly (no widget toolkit).
