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. * app/core/gimpviewable.[ch]: added GimpContext parameters to all get_preview() and get_pixbuf() functions. * app/core/gimpbrush.c * app/core/gimpbuffer.c * app/core/gimpdrawable-preview.[ch] * app/core/gimpgradient.c * app/core/gimpimage-preview.[ch] * app/core/gimpimagefile.c * app/core/gimppalette.c * app/core/gimppattern.c * app/core/gimpundo.[ch] * app/text/gimpfont.c * app/vectors/gimpvectors-preview.[ch]: changed ::get_preview() and ::get_pixbuf() implementations accordingly. * app/core/gimpdrawable-blend.c * app/core/gimppalette-import.[ch] * app/dialogs/dialogs-constructors.c * app/dialogs/palette-import-dialog.c * app/dialogs/resize-dialog.c * app/display/gimpdisplayshell-layer-select.c * app/display/gimpdisplayshell.c * app/display/gimpnavigationeditor.c * app/paint/gimppaintoptions.c * app/tools/gimpeditselectiontool.c * app/tools/gimptexttool.c * app/actions/gradient-editor-commands.c * app/widgets/gimpaction.c * app/widgets/gimpbrusheditor.[ch] * app/widgets/gimpbufferview.c * app/widgets/gimpcellrendererviewable.c * app/widgets/gimpchanneltreeview.c * app/widgets/gimpclipboard.c * app/widgets/gimpcoloreditor.c * app/widgets/gimpcomponenteditor.c * app/widgets/gimpcontainerbox.c * app/widgets/gimpcontainercombobox.c * app/widgets/gimpcontainereditor.c * app/widgets/gimpcontainerentry.c * app/widgets/gimpcontainergridview.c * app/widgets/gimpcontainertreeview.[ch] * app/widgets/gimpdataeditor.[ch] * app/widgets/gimpdevicestatus.c * app/widgets/gimpdnd.[ch] * app/widgets/gimpdrawabletreeview.c * app/widgets/gimpfiledialog.c * app/widgets/gimpgradienteditor.[ch] * app/widgets/gimpgradientselect.c * app/widgets/gimpitemtreeview.c * app/widgets/gimplayertreeview.c * app/widgets/gimppaletteeditor.[ch] * app/widgets/gimppropwidgets.[ch] * app/widgets/gimpselectioneditor.c * app/widgets/gimpthumbbox.[ch] * app/widgets/gimptoolbox-image-area.c * app/widgets/gimptoolbox-indicator-area.c * app/widgets/gimptooloptionseditor.c * app/widgets/gimpundoeditor.c * app/widgets/gimpvectorstreeview.c * app/widgets/gimpview-popup.[ch] * app/widgets/gimpview.[ch] * app/widgets/gimpviewablebutton.c * app/widgets/gimpviewabledialog.c * app/widgets/gimpviewrenderer.[ch] * app/widgets/gimpviewrenderer-frame.c * app/widgets/gimpviewrendererbrush.c * app/widgets/gimpviewrendererbuffer.c * app/widgets/gimpviewrendererdrawable.c * app/widgets/gimpviewrenderergradient.c * app/widgets/gimpviewrendererimage.c * tools/pdbgen/pdb/drawable.pdb * tools/pdbgen/pdb/gradient.pdb * tools/pdbgen/pdb/gradients.pdb * tools/pdbgen/pdb/image.pdb: added tons of GimpContext members and parameters, implement GimpDocked::set_context() in many widgets.
