* plug-ins/gfig/*.[ch]: Use single centralized functions to
create, load, and save objects, instead of separate functions
for each type of object. A few other miscellaneous fixes.
* plug-ins/gfig/*.[ch]: a bunch of code clean-up and
debugging. Created "classes" for the objects, and
attached functions to classes rather than objects.
* plug-ins/gfig/gfig-dialog.[ch]:
* plug-ins/gfig/gfig-style.[ch]:
* plug-ins/gfig/notes.txt: New files.
* plug-ins/gfig/*.[ch]: Complete reworking of the gfig plug-in.
See 'notes.txt' for a summary of what has changed, and how to use
it now. Plenty of bugs have been introduced, which will take a
while to straighten out.
