I tried this and it compiles fine. For some reason, however, the ui 
doesn't behave properly and I wasn't able to work with it. Could it be 
it requires qt with debug info also?

Anyway, I debugged the oldfashined way (with lots of cout). The crash 
was caused by my ipelet trying to draw a circle with radius larger than 
1.0E15 and centre at (1.0E15,1.0E15). I set a hard limit in my ipelet at 
10000 so it wont invoke the crash. This limit is probably too big, but I 
was unsure how to optimize it.

Thanks, that was perfect for my purposes.

I've attached a patch with my ipelet with this message (use patch -p1 in 
the top level ipe directory) in case anyone else would find it useful. 
It implements adding incircle and excircles to a selected triangle.

Next, I will be needing snapping to intersections involving circles. It 
doesn't seem to be implemented in ipe-6.0 preview 26. I'm willing to 
implement it.

Any advice?

Is anyone else working on it?
