Added a thin black border above and below the projections.
- solidify/style.h (PROJECTION_BORDER): number of pixels to leave dark above and below the face - solidify/level.c (draw_xz, draw_zy, level): increase projection z size by twice the border width - solidify/level.c (draw_xz, draw_zy): offset z coordinates by the border
