as long as it has the same number of bytes. Add
gimp_tile_manager_create_buffer_with_format() for that purpose,
register a format that contains's only a u8 alpha byte, and use that
to extract alpha from drawables.
by adding gegl_buffer_flush() and gegl_tile_source_reinit() in the
drawable's buffer and tiles API, and at some half-ported places that
mix legacy and gegl code.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.
svn path=/trunk/; revision=27913
GimpOperationLayerMode instantiable and add a GimpLayerModeEffects
property to it that we check in ::process() to blend pixels
together.
* app/gegl/gimpoperationlayermode.[ch]: Do the change described
above. Currently only Normal and Addition are implemented. Normal
so that we don't need a special case for the gegl:normal op. Also,
the Dissolve layer mode is not a point op and needs to be
implemented elsewhere.
* app/gegl/gimpoperation*mode.c: Removed.
* app/gegl/gimp-gegl-utils.[ch]: Removed
gimp_layer_mode_to_gegl_operation().
* app/core/gimplayer.c
* app/gegl/Makefile.am
* app/gegl/gimp-gegl.c: Adapt.

* app/gegl/gimp-gegl-utils.[ch]: remove function
gimp_bpp_to_babl_format_linear() and add "gboolean linear"
parameter to gimp_bpp_to_babl_format().
* app/gegl/gimpoperationtilesink.c (process)
* app/gegl/gimpoperationtilesource.c (prepare): simply pass
self->linear to above changed function instead of selecting
between the two old functions.

Address Bug 554983 – Layers Projection using GEGL
* app/gegl/gimp-gegl-utils.[ch]: add (imcomplete) function
gimp_layer_mode_to_gegl_operation() from bug #554983.
* app/core/gimpdrawable.[ch]: add gimp_drawable_get_source_node()
which returns a GimpOperationTileSource for the drawable's
tiles.
(gimp_drawable_real_set_tiles)
(gimp_drawable_configure): set the node's "tiles" property.
* app/core/gimplayer.[ch]: add gimp_layer_get_node() which returns
a GeglNode with proxy "input" and "output" pads to be plugged
into the projection graph. The node has children for opacity,
mask, layer mode and layer offset.
(gimp_layer_translate)
(gimp_layer_add_mask)
(gimp_layer_apply_mask)
(gimp_layer_set_opacity)
(gimp_layer_set_mode): reconfigure the respective nodes.
* app/core/gimpimage.[ch]: keep a "graph" node around and destroy
it in finalize(). Not even a stub, just a silly GEGL dependency.

2007-12-30 Sven Neumann <sven@gimp.org>
* app/gegl/gimp-gegl-utils.[ch]: added new function
gimp_bpp_to_babl_format_linear().
* app/gegl/gimpoperationtilesink.[ch]
* app/gegl/gimpoperationtilesource.[ch]: added boolean property
to
toggle between linear and gamma-corrected data.
* app/core/gimpdrawable-invert.c: assume linear data to be
closer
to the original definition of the invert operation in GIMP.
Enable the GEGL code path per default.
