ben-scans/solidify/face.c
Werner Almesberger 6ac06aab7c Control inclination of the z0 plane. (Needs more work.)
- solidify/face.h (struct face), solidify/face.c (read_face),
  solidify/level.c (draw_map, draw_image): introduce inclination of the z0
  plane
- solidify/level.c (draw_map): make blue z == z0 display more continuous
- solidify/level.c (scroll_event): moved z0 shift to scroll_z
- solidify/level.c (scroll_event, scroll_xy): added manipulation of the
  z0 plane's inclination
