RawDrawImage suggestion - draw IN FRONT of objects and characters. Having to re-set all the walkbehinds is giving me a headche!
The RawDraw functions all draw onto the background scene, therefore it is not technically possible to have it in front.
If you need an image in front of other things, make it an object or a GUI.
You can also use overlay, but there're a limit to this, and they're not drawn "permanently" to the screen.
