2003-11-26 Sven Neumann <sven@gimp.org> * Makefile.am: * configure.in * gimpthumb-1.3.pc.in * libgimpthumb/Makefile.am * libgimpthumb/gimpthumb-enums.h * libgimpthumb/gimpthumb-types.h * libgimpthumb/gimpthumb.def * libgimpthumb/gimpthumb.h * libgimpthumb/gimpthumb-utils.[ch] * libgimpthumb/gimpthumbnail.[ch]: added a first draft of libgimpthumb. The API isn't final and the implementation is incomplete. It compiles but don't attempt to use it yet.
