Cleaned up POV-Ray file handling. New use: solidify -p project
- solidify/Makefile (pov, disp, main.pov): call the main POV-Ray file $(NAME).pov, not main.pov - solidify/Makefile: generate $(NAME).inc - solidify/solid.h, solidify/povray.c (povray_face, povray): accept file name as argument and write to the specified file instead of stdout - solidify/povray.c (height_field): added file error handling - solidify/povray.c (height_field, povray): removed useless matrix argument - solidify/solidify.c (usage, main): new invocation "-p project" to generate POV-Ray output. Removed old isatty() hack. - solidify/Makefile: updated to use solidify -p to generate POV-Ray output
