Icon-O-Matic: Generalize some classes

* Turns PathContainer, ShapeContainer, StyleContainer into Container.
* Makes Shape use Container for storing Tansformers instead of
reinventing the wheel yet again.
* Moves common logic from AddPathsCommand, AddStylesCommand,
AddShapesCommand, and AddTransformersCommand to AddCommand.
* Factors out common logic from two more commands similar to above.
This adds the MoveCommand and RemoveCommand classes.
* Cleans up some code style.

Icon-O-Matic: Make GradientTransformable a BReferenceable

* Switch to using support/Referenceable.h instead of using an older copy
of this code.
* Make GradientTransformable a BReferenceable and fix #12033.

* Merged weak-symbols branch.
* Fixed trivial merge conflict in src/system/libroot/posix/locale/nl_langinfo.cpp
* Fixed gcc 2 compilation of src/system/glue/init_term_dyn.c.

* fixed quite a few selections bugs, most were caused by cyclic notifications,
and the mechanism to prevent them not working...
* could have fixed the "there are still listeners attached" bug (debugger drop)
on exit, I have not seen it again, but I am not sure if it is really fixed
* introduced a way to ask the user, if changes should be saved and then
pick up the line of thought after saving

* Put the remaining libicon.a classes into the BPrivate::Icon namespace.
* Minor cleanup (like removing the extra blank line between the copyright and the
header guard).

big clean up of Save and Export stuff:
* implemented SavePanel that let's you chose the Export format
* introduced DocumentSaver class and several implementations
* Document no longer remembers any entry_refs, but a native
and export document saver, for other export formats than
HVIF, it is no longer necessary to go through the file panel,
simply invoking Export will do
* this makes it much easier to have a custom saver that sends
a message with an HVIF icon to another app instead of saving
to a file
* cleaned up File menu
* last used export format is persistent

Another small fix for Dano/ZETA compilation. Why is it Haiku does not seem
to need stdio.h for printf/fprintf?

* added a little bit of tracing to object destruction, since there
seems to be a problem when quitting the app
* added Undo/Redo commands for numerous operations
- (un)assigning VectorPaths to Shapes
- adding new VectorPaths
- removing VectorPaths
- adding Shapes
- transforming Shapes
- adding Styles
- changing Style color
* there was a mix up in classes inheriting from SimpleListView,
RemoveItemList() gives a list of item pointers, not indices
* GradientControl sent the focus notification to the window instead
of the set BHandler target
* StyleView takes care of transfering the current Style color or
the focused gradient stop color to the CurrentColor object, so
the current color of the SwatchGroup is synced
* small improvement to layout of SwatchGroup
* SwatchGroup no longer knows anything about a Style
* fixed syncing the global Selection to the listview selection
at least for ShapeListView
* implemented cloning Shapes
- added Transformer::Clone(VectorSource& source) to all Transformers
- ShapeListView uses this when dropping shapes with shift pressed
* updated NOTES
* added Transformable::matrix_size, so that "6" isn't hardcoded
everywhere (though it still is at most places)
* added listener interface to TransformBox, this is used by
the new TransformObjectsCommand, as long as the TransformBox still
exists, the command modifies the TransformBox transformation instead
of messing with the objects itself
* fixed hotspot size in TransformBox by using the zoom level of
the CanvasView
* TransformBox rotates/scales correctly around the visible pivot
* fixed TransformCommand toggling to transformation (the diff was bogus)
* Gradient doesn't trigger unnecessary notifications in SetColor()
* CanvasView doesn't eat keyboard events when the GradientControl or
one of the ListViews has focus (is a hack currently...)
* fixed bug in PropertyListView when it calls the PropertyChanged()
hook: because of the notification mechanism, the Properties might
be toast after the hook returns
* moved all GetProperty() implementations from headers into .cpp files

* fixed memory leaks and display bugs
* VectorPath objects were released one two many times
by the Shape PathContainers (they don't acquire when
a path is added, the Shape does that for them) the
PathContainer of the Icon needs to release though, as
it "owns" the paths
* put the Selection class used by PathManipulator into
the PathManipulator namespace, since the compiler seemed
to use the wrong destructor (the one from the generic
Selection class)
* uses a better mechanism to track and render
changed parts of icon


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17903 a95241bf-73f2-0310-859d-f6bbb57e9c96

* add more classes:
PathContainer - a list of VectorPath objects
ShapeContainer - a list of Shape objects
Icon - the object contains VectorPaths and Shapes using these paths
IconRenderer - renders an Icon into a BBitmap using AGG compound shape
rasterization with additional gamma correction
* Shape has a PathContainer instead of a single VectorPath
* Document has an Icon instance
* changed the inheritance of some classes to us Referenceable more


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17873 a95241bf-73f2-0310-859d-f6bbb57e9c96

the first steps towards Icon-O-Matic
* added a framework with many classes that I think will be useful
* currently, the StateView and Manipulator interface are used to
allow editing a single VectorPath object, nothing more... the
CommandStack framework is also used to support Undo/Redo
