improved 3D init programming. NV11 gained 44% speed, NV15 gained 21% speed, NV18 and other cards remain at the same speed. These gains (or about) are in all resolutions, all colordepths. If your CPU is fast enough of course. Bumped version to 0.75. There's no doubt about it, if you use 3D, upgrade!
