Sun Mar 1 15:18:38 PST 1998 Shawn T. Amundson <amundson@gimp.org> * Required changes for version change to 0.99.4 * gtk/gtktree.[ch]: patch from J. Bolliet to correct some bugs * gtk/testgtk.c: added test here from J. Bolliet, removed testtree * gtk/clist: gtk-abilleira-981602-0, allows gtk_clist_set_pixmap and gtk_clist_set_pixtext to not require a mask * gdk/gdkdraw.c,gdk.h: gtk-trow-980217-0 adds gdk_draw_lines and fixes some things about gdk_draw_polygon
