Calculate the surface bitangent for the three supplied vertices and UV coordinates and store the result in <code>dest</code>.
@param v1
XYZ of first vertex
@param uv1
UV of first vertex
@param v2
XYZ of second vertex
@param uv2
UV of second vertex
@param v3
XYZ of third vertex
@param uv3
UV of third vertex
@param dest
the binormal will be stored here
