and get rid of the brainfuck idea that app/ has to use _gimp_unit_foo()
functions, passing a gimp pointer. Instead, simply use the libgimpbase
API all over the place. Should we ever allow more than one gimp instance,
they will simply have to share one unit database.
gimp_drawable_get_mode_node() was calling gimp_drawable_get_node()
instead of gimp_item_get_node() if the mode_node didn't already exist.
Fortunately that was never the case i nthe current code. Added
warnings in the GimpItem::get_node() impls that would go off in such a
situation.
because the device info container wants to be displayed in a container
view soon. Also we are about to get lists of tool presets and stuff,
which are also contexts.
Add gimp_image_new_from_drawable(), from_component() and from_pixbuf()
and remove that duplicated code from gimptoolbox-dnd.c and
gimpdisplayshell-dnd.c
Don't write to the string returned by gimp_object_get_name(). Pull
most of the code out of the inner loop (which also means to allocate
only one instead of three strings in the inner loop). Don't use the
object as storage for the name that gets generated in the inner loop.
Also, a space can't hurt so it's now "Foo #1" instead of "Foo#1".
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.
this is pretty pointless from an abstraction point of view, but using
these functions will make the code a lot more readable by getting rid
of tons of ugly casts to and from GimpViewable whenever getting an
item's parent.
and use them from gimp_image_add,remove_layer,channel,vectors().
Removes quite some code duplication from the remove() functions but
almost none from add() because of the ongoing floating selection
madness. We need the calls to the item tree anyway because it's
going to ensure unique names of its items.
- get rid of the individual undo types and add GIMP_UNDO_ITEM_REORDER.
- replace the pushing functions by a single one.
- merge all the actual undo code into gimpitempropundo.[ch].
- use gimp_item_tree_reorder_item() to do the actual reordering.
- fix gimp_item_tree_reorder_item() to use an ordinary "push_undo"
boolean again instead of a pointer to an undo function.
GimpVectorsPropUndo is now a completely empty skeleton. Keep it around
anyway, maybe we'll get vectors properties to undo soon.
and remove the code duplication in gimp_image_reorder_layer(),
_channel() and _vectors(), which now consist of a single call to
gimp_item_tree_reorder_item().
