Techtree Base Grid
Two grids to help getting the positions for techs right. They are also quite handy when used as a semi-transparent layer for painting the techtree background. The grids are checkerboard pattern with a small dark/light grid superimposed on a large green/blue grid. One is (10x10/100x100) and the other is (16x16/128x128).
Copy the the desired grid over the gfx/interface/tech_*.bmp (remember to make a backup).
