Bezier-Arrows don't seem to work

[Krzmbrzl]

When trying to use the Bezier-arrows from the arrow-dropdown nothing happens. This might be because I am using them in the wrong way (The same way I'm using the "regular" arrows), because they're buggy or (my guess) because they're not yet implemented.

I tend to suspect the latter as I couldn't find any reference (except for some strings) inside the source code for Bezier.

Whatever the actual reason for this might be: It would be neat to have them.
