898970b3dd Instead of performing the tranformations stepwise for each point, pre-calculate 
them once.

- solidify/matrix.h, solidify/matrix.c: 2D matrix operations
- solidify/Makefile (OBJS): added matrix.o
- solidify/face.h (struct matrix): moved to solidify/matrix.h
- solidify/overlap.c (point, merge_matrix, draw_map): precalculate a single
  vA+b transformation instead of stepwise transforming the vector inside
  the loop
- solidify/overlap.c (do_shift): now that the math is right (or at least
  better), reverse the shift

37e840fa77 Infrastructure for generating POV-Ray output (not useful yet) 
- solidify/Makefile: added solid.o
- solidify/solid.h, solidify.c (height_field, povray): output the part as
  the intersection of two height fields
- solidify/solidify.c (main): generate POV-Ray output if stdout is
  redirected
- solidify/Makefile (run, pov, disp): targets to run a test setup, render
  it, and display the result
- solidify/main.pov: simple scene showing the test part

edb12b6e95 When leveling, the center circle is now shown when the pointer approaches it. 
- solidify/Makefile: added util.o
- solidify/util.h, solidify/util.c (draw_circle): wrapper for gdk_draw_arc
- solidify/Makefile: added style.o
- solidify/style.h, solidify/style.c, solidify/solidify.c (main): GUI style
  parameters and items
- solidify/level.c (scroll_z. scroll_xy, scroll_event, level),
  solidify/overlap.c (scroll_event, overlap): renamed "da" to "darea", to
  avoid confusion with "da" for GdkDrawable in style.c
- solidify/level.c (r_center, scroll_event): moved center radius
  calculation to separate function
- solidify/level.c (draw_image): renamed to draw_map
- solidify/level.c (draw_image): draw an on-screen display (OSD)
- solidify/level.c (scroll_z, scroll_xy, expose_event, level): propagate
  OSD on/off switch
- solidify/level.c (scroll_event, motion_notify_event, level): enable OSD
  when approaching the center circle

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

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)
