2003-11-15 Henrik Brix Andersen <brix@gimp.org> * libgimpmath/gimpmatrix.c (gimp_matrix4_to_deg): added an inline gtk-doc stub to be filled in. Someone please fill this in... * devel-docs/libgimpmath/tmpl/gimpmatrix.sgml * devel-docs/libgimpmath/tmpl/gimpvector.sgml * devel-docs/libgimpmath/tmpl/gimpmath.sgml: added descriptions * devel-docs/libgimpmath/libgimpmath-sections.txt: reordered functions * libgimpmath/gimpvector.[ch]: reordered functions here as well to be consistent, touched up the inline gtk-docs
