Box2D Wrapper enhancement

[GoogleCodeExporter]

I have libGDX 0.9.7 and I can't find the method 
com.badlogic.gdx.physics.box2d.Contact#setTangentSpeed(float), which should be 
available with newer Box2D versions.

A "proof" that it exists is this blog post:
http://www.iforce2d.net/b2dtut/conveyor-belts

He uses the method at line 25 in the 4th code block.

Here it is in the box2D source:
http://code.google.com/p/box2d/source/browse/trunk/Box2D/Box2D/Dynamics/Contacts
/b2Contact.h#139

In the blog post link you can see for what it can be useful.
For example making a wheel of a car have more grip than another wheel. You do 
this by "faking" the grip and simply making the wheel push the car more than 
usual, simply by changing the tangent speed in the Contact Listener's 
preSolve(...) method.

Isn't this a question for the libGDX mailing list/forums? :)

Yup, not a Box2D issue.

Yes, sorry, i don't know how I could mix this up. This wasn't intended. :)
