525e1557ec Use two faces and show how they overlap (in progress) 
- solidify/face.h (face_z0): calculate height of z0 plane
- solidify/level.c (draw_image): use face_z0 instead of open-coding the
  calculation
- solidify/overlap.c (draw_image, point): moved per-point processing from
  draw_image() to point()
- solidify/overlap.c (point): show differences between both faces
- solidify/solidify.c (usage, main): load both faces
- solidify/solidify.c (usage, main): accept distance between faces as third
  argument

1fa23c574e Introduce a solid data type and use it, mainly in overlap() 
- solidify/solid.h: definition of a solid made from two opposing faces
- solidify/overlap.h (overlap), solidify/overlap.c (draw_image,
  scroll_event, overlap): operate on solid instead of face
- solidify/overlap.c (sx, sy, draw_image, overlap): helper functions sx()
  and sy() to determine canvas size
- solidify/overlap.c (BORDER, sx, sy): added a border around the piece,
  to help with positioning
- solidify/solidify.c (clicked, gui_buttons, gui, main): use solid instead
  of faces

b8bba1d3ab The GUI can now switch among operations. 
- solidify/level.c (key_press_event, make_screen), solidify/solidify.c
  (key_press_event): moved "q" handler to solidify.c
- solidify/level.h (level), solidify/level.c (make_screen, level): removed
  root window initialization and merged remainder into "level"
- solidify/overlap.h (overlap), solidify/overlap.c (make_screen, overlap):
  removed root window initialization and merged remainder into "overlap"
- solidify/solidify.c (gui): initialize the root window
- solidify/solidify.c (gui, gui_buttons, clicked): added buttons to select
  operation

fbbbd29a28 Minor level.c cleanup. 
- solidify/level.c (draw_map): remove, and use draw_image instead
- solidify/level.c (scroll_z): removed commented-out root->window
  initialization

cef7cd5e18 Added interactive 2D transformation (working towards overlapping) 
- solidify/Makefile (OBJS): added overlap.o
- solidify/Makefile (CFLAGS): added -O9 to speed up rotation a little
- solidify/array.h, solidify/array.c (get_bounded): like get(), but returns
  UNDEF if the indices are outside the array
- solidify/face.h (struct face, struct matrix), solidify/face.c (read_file):
  added a 2D transformation matrix to "struct face"
- solidify/overlap.h, solidify/overlap.c: show a face with 2D transformation

8eed5e3ecb Makefile cleanup and instrumentation (verbosity, dependencies, etc.) 
- solidify/Makefile: added verbosity control (default is silent, enable
  verbose output with V=1)
- solidify/Makefile: added "spotless" target
- solidify/Makefile (CFLAGS): moved warning options to CFLAGS_WARN
- solidify/Makefile: added dependency use and generation, with friendly
  permission from fped/Makefile

06b1b08c47 Added red and green band to blue band as further visual clues. 
- solidify/level.c (draw_map): moved open-coded "almost at the same height"
  parameter to constant NEAR
- solidify/level.c (draw_map): draw green and red band next to the "near"
  blue band

b5a2d5d8ef Files can now be specified as HTTP/HTTPS URLs. 
- solidify/face.c (read_face): moved code into new function read_file
- solidify/face.c (read_face): added wrapper for cached wget of http: and
  https: URLs

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

ecf993e0f2 solidify: set the initial height to the median; uncompress .bz2 on the fly. 
- solidify/Makefile, solidify/histo.h, solidify/histo.c: generate a Z
  histogram and find the median height
- solidify/face.c (read_face): set z_ref to the median, not the average
- solidify/face.c (read_face): uncompress .bz2 files on the fly
- solidify/face.c (read_face): don't close standard input (for style)
