app/widgets/Makefile.am new file defining the available help topics. Work 2003-08-21 Michael Natterer <mitch@gimp.org> * app/widgets/Makefile.am * app/widgets/gimphelp-ids.h: new file defining the available help topics.

Renamed some menu callbacks to be consistent with similar ones. This is just an intermediate commit and not finished. While browsing all the menus, I noticed that our "x to selection" functions are not consistent at all. They should all offer the REPLACE,ADD,SUBTRACT,INTERSECT options: * app/core/gimpchannel.[ch]: added new function gimp_channel_new_from_alpha(). Removed gimp_channel_layer_alpha() and gimp_channel_layer_mask(). * app/core/gimpimage-mask.[ch]: added gimp_image_mask_select_alpha() and gimp_image_mask_select_component() which offer the full set of operation, feather and feather_radius parameters as the other selection functions. * app/core/gimpimage-mask-select.[ch]: removed gimp_image_mask_layer_alpha() and gimp_image_mask_layer_mask(). * app/gui/channels-commands.c (channels_channel_to_selection): use gimp_image_mask_select_component() instead of implementing it here. * app/gui/image-menu.c * app/gui/layers-commands.[ch]: offer the full choice of REPLACE,ADD,SUBTRACT,INTERSECT with "Alpha to Selection" and "Mask to Selection". * tools/pdbgen/pdb/selection.pdb: changed accordingly. * app/pdb/selection_cmds.c: regenerated.

This is no longer possible because the libgimpui headers don't inlcude "libgimp/gimpunit.h" any more.
