Description

Hi,

I think there's a bug in the Matrix4.RotatX, RotatY, and RotateZ methods. The negative sign seems to be consistently on the wrong sine. I think (though am not positive) that this would be correct for a left-hand coordinate system. OpenTK is a right hand coordinate system though, correct? If so, this should be changed.

I also had this and other minor incompatibility issues so I ended up using my own Matrix4 and VectorN classes. I think OpenTK is left handed, unfortunately.
