1999-03-16 Michael Natterer <mitschel@cs.tu-berlin.de> This implements the rest of the unit system (unitrc loading and saving and full PDB interface) * Makefile.am * gimp.1 * user_install * user_install.bat * unitrc: new file (default unit database) and some documentation * app/Makefile.am * app/gimpunit.c * app/gimpunit_cmds.h * app/unitrc.h: new files enabling the unit database and PDB access to the unit system * app/app_procs.c: parse and save unitrc * app/gimprc.[ch]: enable unit parsing. New function init_parse_buffers() to enable unitrc to be loaded before gimprc * app/gimage_cmds.[ch]: new PDB procedures which set/return an image's unit * app/install.c: mention unitrc installation * app/xcf.c: new xcf property for user defined units. An image's unit is saved as either an integer ID (built in units) or as a full unit definition without any ID * libgimp/Makefile.am: moved gimpunit.o from libgimpi.a to libgimp.a * libgimp/gimp.h * libgimp/gimpimage.c: get/set an image's unit with PDB calls * libgimp/gimpunit.h: this file is now the header for both app/gimpunit.c and libgimp/gimpunit.c * libgimp/gimpunit.c: does the unit calls as PDB calls now * libgimp/gimpunitmenu.[ch]: enable user unit functionality and a unit selection dialog * libgimp/gimpsizeentry.c: disble hilighting on focus_in_event and minor bugfixes * plug-ins/tiff/tiff.c: set image unit to "mm" if tiff unit is "cm", save "cm" if image unit is metric
