2002-06-12 Michael Natterer <mitch@gimp.org> * app/core/gimpdata.[ch]: added a boolean "internal" which indicates that the data object is an automatically created internal object. Changed the code to refuse saving to deleting internal objects. * app/core/Makefile.am * app/core/gimp-gradients.[ch]: new files implementing internal gradients (FG -> BG in RGB and HSV and FG -> transparent). * app/core/gimp.c: call gimp_gradients_init(). * app/core/gimpdatafactory.c (gimp_data_factory_data_free): don't free internal objects so they stay there on "Refresh". * app/core/gimpdatalist.c: sort internal objects to the beginning of the list. * app/widgets/gimpdataeditor.c: refuse to change the name of internal objects. * app/widgets/gimpdatafactoryview.c: set the "Delete" button insensitive for internal objects. * app/widgets/gimpgradienteditor.c: refuse to edit internal gradients, just display them so color picking works. * app/gui/brushes-commands.c * app/gui/gradients-commands.c * app/gui/palettes-commands.c * app/gui/patterns-commands.c: set the "Delete" menu item insensitive for internal objects. * app/gui/gui.c: need to call render_setup() earlier because of you-dont-want-to-know-why. Will change it back once the previews have their own render buffers. * app/tools/gimpblendtool.c: Replaced the "Type" menu by a preview showing the active gradient. Clicking the preview pops up the gradient selection. Renamed the "Gradient" menu to "Shape". Removed "blend_mode" from the BlendOptions struct because we always use "custom" mode now.
