[Freeciv-Dev] (PR#23) Wishlist: low fuel indicator for air units

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=23 >

Here's a simple patch to draw a low-fuel sprite for air units.  It's not
very sophisticated, and isn't of any use unless the tileset actually has
such a sprite.
