fixed the GUI trouble in both master and 2.0 branches.

Please confirm with the latest nightly builds:

Now, the 90 degree issue was an illusion caused by the positioning of the tangential arc.

I have updated the tangential arc calculation algorithm in the master branch, and drawing arc by almost (0, 360) degrees is supported.

If this turns out to be stable, we will add this algorithm to the 2.0 stable branch.

Thanks dxli,
I just discovered yet another strange behaviour:
once you manage to set the angle, say 90° and you draw the arc at the end of a line, the actual angle you get is 90/2, i.e. 45°; apparently it only draws to half the angle set. Why?
Should I not get 90 if that is what I ask for?
I am puzzled with this tool.
Regards,
Christian
