The win32 backend now handles the WM_SETCURSOR message and sets a fully transparent cursor if the cursor-visible property has been cleared on the stage. The icon is stored in the library via a resource file. The instance handle for the DLL is needed to load the resource so there is now a DllMain function to grab the handle.
