Gimp/app/layer.h
Michael Natterer 8d6c335f8f app/Makefile.am app/channel_pvt.h app/drawable_pvt.h app/gdisplayF.h 
2000-12-29  Michael Natterer  <mitch@gimp.org>

	* app/Makefile.am
	* app/channel_pvt.h
	* app/drawable_pvt.h
	* app/gdisplayF.h
	* app/gimpdrawableP.h
	* app/gimpimageP.h
	* app/layer_pvt.h
	* app/toolsF.h: removed these files.

	* app/apptypes.h
	* tools/pdbgen/enums.pl: added tons of opaque typedefs and enums.

	* tools/pdbgen/pdb/brush_select.pdb
	* tools/pdbgen/pdb/brushes.pdb
	* tools/pdbgen/pdb/channel.pdb
	* tools/pdbgen/pdb/color.pdb
	* tools/pdbgen/pdb/convert.pdb
	* tools/pdbgen/pdb/display.pdb
	* tools/pdbgen/pdb/drawable.pdb
	* tools/pdbgen/pdb/fileops.pdb
	* tools/pdbgen/pdb/gradient_select.pdb
	* tools/pdbgen/pdb/gradients.pdb
	* tools/pdbgen/pdb/help.pdb
	* tools/pdbgen/pdb/image.pdb
	* tools/pdbgen/pdb/layer.pdb
	* tools/pdbgen/pdb/pattern_select.pdb
	* tools/pdbgen/pdb/patterns.pdb
	* tools/pdbgen/pdb/selection.pdb
	* tools/pdbgen/pdb/tools.pdb
	* app/*: chainsaw #include cleanup:

	- Never (never!!) include stuff in header files except where we
	  need access to structures' contents (like derived objects).
	- Added prototypes and proper formating in many files.
	- The #include order in *all* *.c files is as follows:

	#include "config.h"

	#include <system stuff>

	#include <gtk/gtk.h>

	#include "apptypes.h"

	#include "gimp stuff"

	#include "libgimp stuff"

	#include "libgimp/gimpintl.h"

	By following this scheme we can easily see a file's dependencies
	from it's #include's and can grep for the inclusion to find out
	where a file is used.

	* tools/pdbgen/app.pl: changed to follow the include scheme above.

	* libgimp/Makefile.am
	* libgimp/gimpuitypes.h: new file, included from libgimp/gimpui.h
	and from app/apptypes.h.

	* libgimp/gimpcolorbutton.[ch]
	* libgimp/gimpdialog.[ch]
	* libgimp/gimphelpui.[ch]
	* libgimp/gimpparasite.[ch]
	* libgimp/gimppatheditor.[ch]
	* libgimp/gimpprotocol.c
	* libgimp/gimpquerybox.[ch]
	* libgimp/gimpsizeentry.[ch]
	* libgimp/gimptypes.h
	* libgimp/gimpui.h
	* libgimp/gimpunit.h
	* libgimp/gimpunitmenu.[ch]
	* libgimp/gimpwidgets.[ch]: changed accordingly.

	* plug-ins/FractalExplorer/Dialogs.c
	* plug-ins/gdyntext/message_window.c
	* plug-ins/imagemap/imap_default_dialog.c
	* plug-ins/imagemap/imap_file.c: these files used to include
	"libgimp/gimpui.h" without including "libgimp/gimp.h". This is
	no longer possible because the libgimpui headers don't inlcude
	"libgimp/gimpunit.h" any more.
