gimp/app/gimpcontext.h
Michael Natterer 78a8bb4c70 app/Makefile.am new object. 
2001-02-04  Michael Natterer  <mitch@gimp.org>

	* app/Makefile.am
	* app/gimppattern.[ch]: new object.

	* app/apptypes.h: added GimpPattern, removed GPattern.

	* app/patterns.[ch]: contains only the "patterns_()" functions for
	the global pattern list, s/pattern_list/global_pattern_list/g

	* app/brushes.[ch]: s/brush_list/global_brush_list/g

	* app/pattern_select.[ch]
	* app/gimpcontext.[ch]: connect to the Patterns' and the pattern
	list's signals.

	* app/brush_select.[ch]
	* app/devices.c
	* app/disp_callbacks.[ch]
	* app/gimpbrush.c
	* app/gimpbrushgenerated.[ch]
	* app/gimpcontextpreview.[ch]
	* app/gimpdnd.[ch]
	* app/indicator_area.c
	* app/pdb/brush_select_cmds.c
	* app/pdb/brushes_cmds.c
	* app/pdb/pattern_select_cmds.c
	* app/pdb/patterns_cmds.c
	* app/tools/bucket_fill.c
	* app/tools/clone.c
	* tools/pdbgen/pdb/brush_select.pdb
	* tools/pdbgen/pdb/brushes.pdb
	* tools/pdbgen/pdb/pattern_select.pdb
	* tools/pdbgen/pdb/patterns.pdb
	* po/POTFILES.in: changed accordingly.
