	Remember the settings in the scale and resize dialogs for images
	and layers. Fixes bug #164995, bug #316392, and bug #357424.

	* app/dialogs/scale-dialog.h: removed GimpScaleCallback typedef.

	* app/dialogs/dialogs-types.h: added it here.

	* app/dialogs/image-scale-dialog.[ch]: made the ImageScaleDialog
	struct private, return a GtkWidget* from image_scale_dialog_new()
	and use a GimpScaleCallback in the public API.

	* app/actions/actions-types.h: #include "dialogs/dialogs-types.h"

	* app/actions/image-commands.c: changed according to image scale
	dialog changes. Remember the scale dialog's unit (if it is
	"percent") and interpolation type across dialog invocations. Also
	remember the resize dialog's unit (if it is "percent").

	* app/actions/layers-commands.c: remember scale and resize dialog
	stuff as in image-commands.c
