Post-translates to the specified points. Output matrix allows for caching objects.
@param transformedPts @return
Implementation
void translate2(final List<double> transformedPts, Matrix4 outputMatrix) {
_matrixTouch.copyInto(outputMatrix);
final double x = transformedPts[0] - offsetLeft();
final double y = transformedPts[1] - offsetTop();
Matrix4Utils.postTranslate(outputMatrix, -x, -y);
}
