[Freeciv-Dev] (PR#11143) don't draw black tiles

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=11143 >

This patch removes a spurious piece of drawing.  For unknown tiles a 
"black tile" is drawn.  However this is unnecessary because we already 
clear the background to black before drawing anything.  For unknown 
tiles we can draw nothing and get the same effect.

This may speed up drawing a tiny bit.  It should be applied to both 
branches I think.
