Maintain the bounding box of drawables (i.e., the bounds of their
actual rendered content) separately from their logical boundary (as
shown in the UI).
The bounding box is calculated through the new
GimpDrawable::get_bounding_box() virtual function, which has a
corresponding gimp_drawable_get_bounding_box() function; the
default implementation simply returns the drawable's logical
boundary. The bounding box is specified in drawable coordinates,
i.e., it's not affected by the drawable's offset.
The bounding box is recalculated through
gimp_drawable_update_bounding_box(), which should be called
whenever a change may affect the bounding box (for example, when
setting a new buffer, as done implicitly by GimpDrawable's
::set_buffer() implementation, or when a drawable filter's
properties change, as will be done by GimpDrawableFilter in a
following commit). When the bounding box changes, the affected
regions of the drawable are updated, and the
GimpDrawable::bounding-box-changed signal is emitted.
When gimp_drawable_update() is called with negative width/height
values, the entire drawable's bounding box is updated, rather than
only its logical boundary.
Likewise, GimpDrawableStack and GimpLayerStack are adapted to use
the bounding box, instead of the logical bounds, when updating the
drawable's area.
which is just a #define to g_assert for now, but can now easily be
turned into something that does some nicer debugging using our new
stack trace infrastructure. This commit also reverts all constructed()
functions to use assert again.
Add an "active" property to GimpFilter, which replaces its
"visible" property. The new property assumes the lower-level role
"visible" had -- controlling whether the filter has any effect as
part of its parent filter-stack.
Add a "visible" property to GimpItem, separate from the "active"
property, which assumes the higher-level role "visible" had --
controlling whether the item is considered "visible", as per the
GUI. By default, the item's "visible" property is bound to the
filter's "active" property, so that changes in visibility directly
affect the filter's "activeness"; this binding can be controlled
using the new gimp_item_bind_visible_to_active() function.
This distinction is currently necessary for floating selections.
Floating selection layers must not be active in their parent stack,
regardless of their visibility, in particular, so that their mode
node doesn't hide the entire backdrop when their composite mode
excludes the backdrop (i.e., when it's dst-atop or src-in).
Instead, their visibility should affect the activeness of the
floating-selection filter of the drawable they're attached to.
This is handled by the next commit.
A subclass of GimpDrawableStack, for layer stacks. Invalidates the
layers' backdrop as/when necessary, according to the value of their
excludes_backdrop property.
Make gimp_drawable_stack_update() protected, instead of private, so
that we can use it in GimpLayerStack.
- don't include <gdk-pixbuf/gdk-pixbuf.h> in headers in app/
- instead, include it in many .c files instead of <glib-object.h>,
finally acknowledging the fact that app/ depends on gdk-pixbuf almost
globally
- fix up includes as if libgimpbase depended in GIO, which it soon will
Add a boolean "is-last-node" property to GimpDrawable and set it from
GimpDrawableStack, which is the place that easily has the information.
In GimpLayer, connect to "notify" and make sure we use NORMAL mode
unless the layer is in NORMAL or DISSOLVE mode.
Switch off unique names for all individual item stacks and make sure
that all items in a GimpItemTree have unique names across all
containers. Uses a hash table and thus gets rid of the O(n**2)
complexity of the unique name code in GimpList.

* 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

* app/core/gimpimage.c: use a GimpItemStack instead of a plain

* app/core/gimpdrawablestack.[ch]: add new function
gimp_drawable_stack_invalidate_previews() which does just what it
says.
* app/core/gimpimage.[ch]: merge invalidate_layer_previews() and
invalidate_channels_previews() into a single invalidate_previews()
and replace all calls to the old functions by calls to
gimp_drawable_stack_invalidate_previews().
* app/file/file-open.c: changed accordingly.

2008-11-02 Michael Natterer <mitch@gimp.org>
* app/core/gimpdrawablestack.[ch]: add "update" signal with the
same signature as GimpImage::update(). Install handlers for the
drawables' "update" and "visibility-changed" signals and emit
"update" accordingly, item offsets taken into account. Also emit
"update" when drawables are added, removed and reordered.
* app/core/gimpimage.[ch]: remove handlers and tons of code that
makes sure the image emits "update" on any of the above handled
events and simply connect the layer and channel stacks' "update"
signal to gimp_image_update().

preparation for moving the GimpLayer gegl:shift op to here as
well. After all, the offsets are properties of GimpItem and not
GimpLayer.

GimpItem base class, like part of the visibility toggling and the
creation and destruction of the GimpItem node.
* app/core/gimplayer.c
* app/core/gimpchannel.c
* app/core/gimpdrawablestack.c: Changed accordingly, use the new

* app/core/gimpdrawablestack.c: add GimpContainer::add()
implementation, it's needed after all even though everybody uses
gimp_container_insert() on drawable stacks.
(gimp_drawable_stack_remove_node): no need to have a special check
for newly added nodes, this can't happen any more now that we have
an add() impl.
(gimp_drawable_stack_get_graph): free the reverse list.

* app/core/gimpdrawablestack.[ch]: move all the code that creates
a graph of drawables and all adding/removing/reordering code from
GimpImage to this file.
* app/core/gimpimage.c: remove the code here and use the layer
stack's subgraph instead. Add #if 0'ed code that blends the
channels on top of that but that doesn't work because channels
don't provide nodes yet.
