More "airplane" work... - rewrote the way we handle lights: glEnable(GL_LIGHTING) is now used at the lowest level, where it belongs. This fixes many lighting glitches, and should make the whole stuff much more predictable; - simplified the display modes for geometry and mesh: the choice between wireframe/solid is now independent of the choice of lighting/no lighting (and there is a new "Enable lighting" option for the geometry, too--even if it does only affect things like normals/tangents at the moment); - brand new code to draw really nice (shaded) 3D arrows + 3 options that fully parameterize them (they can degenerate into pyramids, cones, w/ or w/o stems, etc.); - new options so that we can also use the new arrows outside the post-processing module (e.g. for tangents/normals). - "alt+d" now simply switches between solid and wireframe mode; - new shortcut "alt+w" to switch the lighting mode for all the modules (geo/mesh + all post views) at once.
