LOS issues still outstanding: - LOS looks ugly because of quad tesselation into 2 triangles - Quad tesselation is unspecified by OpenGL (in fact using GL_QUADS on LOS quads seemed to give different tesselations than it did for the underlying terrain quads, but terrain rendering also used GL_QUADS). This should be fixed once we decide on the quad tesselation issue. - Units with traits.vision.permanent set are visible through FOW even if you havent seen them before; this should only be true when you have seen them before. But it gets even more complicated - if a permanent unit seen through FOW dies or gets upgraded or something, perhaps you should remember the old version. I'm not completely sure how to do this (probably involves cloning its actor somehow). This was SVN commit r2876.
