Change all action callbacks so they can be invoked by a GAction:

- add GimpActionCallback typedef:
  void (* cb) (GimpAction*, GVariant*, gpointer)
- change all action callbacks to the GimpActionCallback signature
- add "gimp-activate" and "gimp-change-state" signals to GimpAction,
  with the same signature as the resp. GAction signals
- remove all other custom action signals and only use the new
  GimpAction signals
- pass around appropriate GVariants containing booleans, int32,
  strings
- badly hack around to force a GimpProcedure pointer into a
  uint64 variant
- remove all G_CALLBACK() casts from all action callbacks,
  they all have the same signature now

instead of GtkAction, which is correct now because all our actions
implement the GimpAction interface.

Step one: get rid of all those deprecation warnings that make
it hard to see any other warnings:

- add a lot of dummy API to GimpAction, GimpActionGroup, GimpUIManager
  etc. which simply forwards to the deprecated GTK functions, they
  will all go away again later
- rename GimpAction to GimpActionImpl
- add interface GimpAction that is implemented by all action classes,
  creates a common interface and allows to remove some duplicated
  logic from GimpToggleAction and GimpRadioAction, and at the same
  time adds more features

they are obsolete in GTK+ 3.x because GtkAdjustment cannot be passed
around as GtkObject any longer, GtkObject is gone.

Let the split and replicate segments dialogs keep their own data and
don't use GimpGradientEditor struct members. Remove redundant members
and indent the struct.

Add gimp_gradient_editor_get_selection() and set_selection()
and use them in gradient-editor-commands.c

Same as previous commits.

...and gone are the annoying warnings.

Found via `codespell` and grep.

First WIP commit, adds:

- enum GimpGradientBlendColorSpace { RGB_PERCEPTUAL, RGB_LINEAR }
- linear blending mode for gradient segments
- tool options GUI for the blend and paint tools which use gradients

Use gimp_gradient_get_{left,right}_flat_color(), instead of
gimp_gradient_get_color_at(), to get the selection endpoints'
colors in the gradient editor, so that the correct colors are used
under any condition (in particular, if there are 0-length
segments.)

Try to sort all GIMP_ICON_* defines into FDO categories like in
https://specifications.freedesktop.org/icon-naming-spec/latest/ar01s04.html

Add defines for all icons we override, rename some icons to their FDO
standard names, and mark the ones we duplicate with a comment so we
don't forget to rename those to standard names in 3.0.

Nobody has them anymore, and they are deprecated in GTK+ 3.x. This
also fixes all conflicting mnemonics except those I missed, but we can
fix them now.

Check for valid GimpGradientSegmentType and GimpGradientSegmentColor
enum values before updating gradient segment.

...at least not most of the time, gradients are beasts. Also some
unrelated minor cleanup.

which takes a Babl format to convert from/to.
Include <gegl.h> in a million places.

and use it all over the place. Also change some GtkObject* variables
to GtkAdjustment*.

- return TRUE from event handlers if we handled the event
- remove the "instant update" toggle and feature
- move the color area left of the labels now that the toggle is gone

because the packing options are different for GtkH/VBox and GtkBox
itself which is now instantiable. Instead, always use
gtk_box_pack_start() and specify expanding explicitely.

Instead of including dialogs/dialogs.h everywhere, introduce
gimp_dialog_factory_get_singleton(). The dialog factory singleton is
still initialized by dialogs.c though.

Right now the assumption is that we never will have another dialog
factory instance around. There were so many problems before when we
had four of them, so let's just keep one of them around.

This is not a problem of gimp_gradient_get_color_at(), but a typo
in gradient_editor_right_color_update().

This is not a problem of gimp_gradient_get_color_at(), but a typo
in gradient_editor_right_color_update().

	* app/actions/gradient-editor-actions.c
	* app/actions/gradient-editor-commands.[ch]: added actions and
	callbacks to select a gradient segment's left and right color
	type. Handle FG/BG color correctly in a few places. Use
	GimpDataEditor's context instead of the user context.

	* menus/gradient-editor-menu.xml: added the actions to the menu.

	Cleanup:

	* app/actions/palette-editor-commands.c: use GimpDataEditor's
	context instead of the user context.

	* app/actions/brush-editor-actions.c: remove unused context
	variable.

2006-08-29  Michael Natterer  <mitch@gimp.org>

	Changed GimpViewable preview rendering to have a context to get
	FG/BG/whatever from. Use the context to enable dynamic FG/BG
	colors in gradients. Fixes bug #127676 and bug #352214. Addresses
	bug #128367 (doesn't fix it because there's no loading/saving and
	no GUI yet).

	* app/core/core-enums.[ch]: added enum GimpGradientColor to enable
	specifying gradient colors in terms of foreground and background.

	* app/core/gimpgradient.[ch]: added color_type members to the
	GimpGradientSegment struct and honor them in
	gimp_gradient_get_color_at(). Added GimpContext parameters to all
	functions which finally call get_color_at().

	* app/core/gimp-gradients.c: use the new method to implement the
	builtin gradients.

2005-05-27  Sven Neumann  <sven@gimp.org>

	* (lots of files): Use the canonical form for signal names.

2005-05-06  Michael Natterer  <mitch@gimp.org>

	* app/actions/gradient-editor-commands.h: added enum for the
	"load_color" actions.

	* app/actions/gradient-editor-actions.c
	* app/actions/gradient-editor-commands.c: use the new enum instead
	of magic values, cleanup.

	* app/actions/palette-editor-commands.c: cleanup.

	* app/widgets/gimpbrusheditor.c
	* app/widgets/gimpdataeditor.c: cleanup.

	* app/widgets/gimpgradienteditor.c: added GtkObject::destroy() and
	GtkWidget::unmap() implementations which destroy the color dialog.
	Destroy color dialogs by cancelling them via gtk_dialog_response(),
	so temporarily changed colors are restored correctly. Refactored
	my last commit below a bit. Various cleanups.

	* app/widgets/gimppaletteeditor.[ch]: no need to remember the
	buttons in the GimpPaletteEditor struct.

2005-02-27  Sven Neumann  <sven@gimp.org>

	* app/core/gimpgradient.[ch]: removed the "last_visited" field
	from GimpGradient. Instead added the new function
	gimp_gradient_get_color_at_segment() that allows the caller to do
	the same optimization.

2004-12-21  Michael Natterer  <mitch@gimp.org>

	* app/actions/gradient-editor-actions.c
	(gradient_editor_actions_update): if the dialog is insensitive,
	disable all actions which modify the gradient. Fixes bug #161411.

	* app/actions/gradient-editor-commands.c: update the UI manager
	after setting the dialog sensitive/insensitive so te above works.
