Atm we provide 2 FFI functions to set the radar on the eventmonitor and 1 Lua function to unset the radar again. This is quite inconsistent, so we'd rather use FFI functions only.
In addition, we'd rename the functions to explicitly represent that these are controlling the radar display. The old functions should be deprecated and replaced with new ones as follows:
(Lua) UnsetMapRenderTarget() -> (FFI) UnsetRadarRenderTarget()
(FFI) SetMapRenderTarget() -> (FFI) SetRadarRenderTarget()
(FFI) SetMapRenderTargetOnTarget() -> (FFI) SetRadarRenderTargetOnTarget()
