Weather radar

Knowing the position of clouds, a fake radar image is drawn into a texture.
This texture is then used in a standard 2D or 3D instrument as if it was a standard texture loaded from disk.
This kind of instrument is hardly done with standard instrument code because of varying and number of thing to draw. The use of a texture target add the opportunity to rebuilt the radar echo with a low frequency.
