[chuck-users] Mesh2D chugin: problem with setting .xpos/.ypos

[Joel Matthys]

Ah! You found a bug! Did you build the Mesh2D chugin from source? You 
can fix it by changing line 137 of Mesh2D.cpp from int to float and 
recompiling.

I'll submit a pull request to fix it in git.

Thanks for finding this!
