Largely based on a patch by Ell, with the enum type renamed and
various small changes. Adds another axis of configurability to the
existing layer mode madness, and is WIP too.
from gimp_applicator_new() and gimp_gegl_mode_node_set_mode().
Compositing doesn't depend on the layer format any longer, only on the
layer mode. Painting with "use applicator" unchecked is still broken
in some cases and needs more fixing.
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
When set, it crops the effect to that rectangle, using a cache for
quickly changing the previewed area. When disabling the preview rect,
make sure we don't lose the cached result by processing it into the
output cache through the mode and affect nodes which is cheap-ish.
Add "gboolean use_cache" to gimp_applicator_new(). Don't use a cache
anywhere but in GimpImageMap because it incrementally fills that cache
via the projection update. In gimp_drawable_merge_filter(), get that
cache and pass it to gimp_gegl_apply_cached_operation() which then
avoids doing the work twice for the already cached results. Win!
Add "linear" parameter to GimpApplicator. Pass the drawable's "linear"
to the applicator, and to all calls to gimp_gegl_mode_node_set_mode(),
instead of hardcoding FALSE everywhere.
which means adding a lot of proper API. Input, output and aux can be
pads or buffers. Make sure it uses the minimum possible graph in all
cases and doesn't reconfigure nodes unless needed. Port GimpPaintCore
to the new API.
and use it in GimpPaintCore, instead of calling
gimp_drawable_apply_buffer() which sets up a new graph for each
call. Makes painting speed bearable again.
