It's true this function is missing in native

Thanks to have sharing this great code

Really great piece of code!

My two cents:
- you should remove props with RemoveProp_() on WM_NCDESTROY
- it would be much better and more optimal to allocate structure and write its pointer with SetProp_() instead of using many props (one call vs eight)
