Does anyone have a recommendation for drawing routines which would work
nicely on an avr. Anti aliasing of some description would be nice.

No direct experience but I think it’s never going to be very fast due to
the need for floating point & trig functions, and the lack of FP support
on the AVR. Also, are you going to have to buffer the image in the AVR?
If so, memory is also going to be a problem. A quick google shows up a
few candidates (e.g. http://www.idleloop.com/robotics/OLEDsample/) but
they all seem to be specific to individual displays - what one do you have?

You don’t need trig or fp for Bresenham’s algorithms, though I don’t
know if they cover antialiasing.

They don’t, seemingly you need Xiaolin Wu’s for that, but those look
like they need FP.
