added "gboolean data_editable" which gets set in

Browse Source 
2003-03-10  Michael Natterer  <mitch@gimp.org>

	* app/widgets/gimpdataeditor.[ch]: added "gboolean data_editable"
	which gets set in gimp_data_editor_real_set_data(). Set the name
	entry insensitive if the data is not editable.

	* app/widgets/gimpbrusheditor.c
	* app/widgets/gimppaletteeditor.c
	* app/widgets/gimpgradienteditor.c: look at editor->data_editable
	instead of duplicating the logic in all subclasses.

	* app/widgets/gimppreview.[ch]: added "gboolean expand" and
	gimp_preview_set_expand() like in GtkPreview bacause smooth auto
	resizing can only be done by the widget itself, not via external
	callbacks.

	* app/display/gimpnavigationview.c
	* app/widgets/gimpbrusheditor.c
	* app/widgets/gimpgradienteditor.c
	* app/widgets/gimpselectioneditor.c: set expand == TRUE. Removed
	"size_allocate" callbacks. They resize *much* smoother now.
	Various cleanups.

	* app/widgets/gimpnavigationpreview.c: recalculate the preview
	coordinates when the size changes.

	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimppreviewrenderer-utils.c
	* app/widgets/gimppreviewrenderergradient.[ch]: new renderer which
	is much faster because it projects the gradient without creating
	intermediate buffers. Rendering can be restricted to an interval
	from [left...right].

	* app/widgets/gimpgradienteditor.[ch]: undeprecated by using
	GimpPreview instead of GtkPreview. Cleanup.

	* app/gui/gradient-editor-commands.c: changed accordingly.
