NAME
    cross - returns the cross product of two three-component vectors

SYNOPSIS
      float3 cross( float3 a, float3 b );
 
      half3  cross( half3 a, half3 b );
 
      fixed3 cross( fixed3 a, fixed3 b );

PARAMETERS
    a       Three-component vector.

    b       Three-component vector.

DESCRIPTION
    Returns the cross product of three-component vectors *a* and *b*. The
    result is a three-component vector.

REFERENCE IMPLEMENTATION
    cross for float3 vectors could be implemented this way:

      float3 cross(float3 a, float3 b)
      {
        return a.yzx * b.zxy - a.zxy * b.yzx;
      }

PROFILE SUPPORT
    cross is supported in all profiles.

    Support in the fp20 is limited.
