Currently, the outline of the unit does not matter for selecting it.
We have to build the renderer (#34 #286 #287) in such a way we can tell which pixel belonged to what unit.

This allows us to click anywhere in the game and then determine what object was drawn there.

#1688 now implements that for targeting (but not selection)
