Michael Natterer 075195d16b added "gboolean reverse" to gimp_gradient_get_color_at() so all gradients
2003-07-22  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpgradient.[ch]: added "gboolean reverse" to
	gimp_gradient_get_color_at() so all gradients can be used
	reversed.

	* app/core/gimpdrawable-blend.[ch] (gimp_drawable_blend)
	* app/core/gimppalette-import.[ch] (gimp_palette_import_from_gradient):
	added "gboolean reverse".

	* app/paint/paint-enums.[ch]: removed enum GimpGradientRepeatMode
	since it is identical to GimpRepeatMode, except for the now
	obsolete ONCE_BACKWARD value.

	* app/paint/gimppaintcore.[ch]: removed
	gimp_paint_core_get_color_from_gradient()...

	* app/paint/gimppaintoptions.[ch]: ...and added
	gimp_paint_options_get_gradient_color(), which is much more
	general. Added a "reverse" property to GimpGradientOptions and
	changed the type of the "repeat" property to GimpRepeatMode.

	* app/paint/gimppaintbrush.c: use
	gimp_paint_options_get_gradient_color().

	* app/tools/gimpblendoptions.[ch]: removed the "repeat" property
	since it is in the parent class now.

	* app/gui/gradient-select.c
	* app/gui/palette-import-dialog.c
	* app/widgets/gimpgradienteditor.c
	* app/tools/gimpblendtool.c
	* tools/pdbgen/pdb/gradients.pdb
	* tools/pdbgen/pdb/misc_tools.pdb: changed accordingly.

	* app/tools/gimppaintoptions-gui.c: added a "Reverse" toggle right
	of the gradient preview.

	* app/widgets/gimppreviewrenderergradient.[ch]: added "gboolean
	reverse" member and gimp_preview_renderer_gradient_set_reverse()
	API.

	* tools/pdbgen/pdb/paint_tools.pdb: fixed the paintbrush invoker
	to set GimpPaintOption's "use-fade" and "use-gradient" properties
	correctly.

	* app/pdb/gradients_cmds.c
	* app/pdb/misc_tools_cmds.c
	* app/pdb/paint_tools_cmds.c
	* libgimp/gimpenums.h
	* libgimp/gimpmisctools_pdb.[ch]
	* plug-ins/pygimp/gimpenums.py
	* plug-ins/script-fu/script-fu-constants.c
	* tools/pdbgen/enums.pl: regenerated.

	* libgimp/gimpcompat.h
	* plug-ins/script-fu/siod-wrapper.c: removed GimpGradientPaintMode
	here too since it was only exported accidentially (it's not used
	by any external API).

	* plug-ins/script-fu/scripts/textured-logo.scm
	* plug-ins/script-fu/scripts/title-header.scm
	* plug-ins/script-fu/scripts/weave.scm: pass "reverse" to
	gimp_blend(). Pass FALSE in most cases and added script
	parameters were it makes sense.
