Alawys clip a floating selection to its base layer, if the layer
has no alpha channel. This avoids arbitrarily filling the extended
regions of the layer with, or compositing the floating selection
against, black color.
This is a temporary solution. Ideally, we'd automatically add an
alpha channel to the layer as necessary.
When the bounding box of a floating selection changes, update the
bounding box of the associated drawable, since floating selections
are no longer clipped to the drawable's bounds in general.
When attaching a floating selection to a layer, don't clip the
floating selection to the layer's boundary, and instead resize the
layer to include the entire floating selection when it's anchored.
As per the last commit, this can be prevented by locking the
layer's position.
Remove the use_split_preview and use_result_cache parameters of
gimp_applicator_new(), and allow enabling/disabling the cache
(through gimp_applicator_set_cache()) and the preview crop (through
gimp_applicator_set_preview()) after construction.
Move the preview crop node after the result cache, and remove the
separate preview cache node. This eliminates an extra cache
buffer, reducing the space consumed by filters, and speeds up split
preview, since the cached result now includes the output
compositing.
Set the output format of floating-selection applicators to the
target drawable format. We're going to remove the global
GipDrawable convert-format node, which we use to get correct
previews for indexed drawables, so that each filter now has to do
its own format conversion.
When attaching a layer as a floating selection to a drawable,
unbind its visiblility from its activeness, as per the previous
commit, and use its visibility to control the activeness of the
drawable's floating selection filter.
Properly update the drawable when the floating selection's
visibility and excludes-backdrop properties change.
More than 2000 lines of code less in app/, instead of
if (instance->member)
{
g_object_unref/g_free/g_whatever (instance->member);
instance->member = NULL;
}
we now simply use
g_clear_object/pointer (&instance->member);
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.
