is it possible in next LuaRT release to expose the raw WIn32 handle of a ui.Panel through a property? this could be a starting point to use FFI to interact with custom DLLs showing their video or graphics, with their thread(s) if needed. Anyway, I have some concerns about updates in case LuaRT windows containing the "special" panel are moved, resized, etc. (I exclude any mouse/keyboard user input for the custom panel to simplify).
