+Tangent space normal mapping shader for a single directional light source.
+
+The tangent vector is passed to the vertex shader in gl_MultiTexCoord1. The
+tangent vector is assumed to be a four component vector. The tangent vector's
+w component indicates the handedness of the local tangent space at this vertex.
+The handedness is used to calculate the bitangent vector. The reason for the
+inclusion of the handedness component is to allow for triangles with mirrored
+texture mappings.
