* Small cleanups.
* Do not implement backbuffering. Besides being inefficient on Haiku it solves
the grey area on start up.
* Reimplement scrolling and layouting the canvas. The mouse cursor is now the
anchor when scrolling with the mouse wheel.

culmulative update...
* holding down space, or using the third mouse button, will force
the "pan canvas" mode
* using the mouse wheel zooms in and out
* fixed issues with the undo commands when nudging something with
the cursor keys
* manipulators can now indicate wether they changed the mouse cursor
* ChangePointCommand is no longer inserted if the point didn't change
* new "flip" points feature in context menu, flips "in" and "out" curve
control points
* mouse wheel events are now propagated together with the mouse position
* new "UndoesPrevious" method in Command interface (used to clean up
command stack)
* clean ups in CommandStack

* fixed the dirty canvas when Icon-O-Matic is started in Haiku
(and also improved performance of rendering icons, the background
was cleared for no reason on each Draw() call) However there
must be a bug still in the app_server which causes GetClippingRegion()
to return an out-of-date clipping region (R5 has the very same bug
though)

* fixed stupid bug that prevented saving in native format
* fixed bug in RDefExporter
* improved zooming, icon is now centered at program start

* started work on saving program settins, window frame is
remembered for now
* fixed some annoying bugs:
- the snapping prevented some of the proximity checks from
working while editing a path or using the transform box,
now the Manipulators themself are responsible for mouse
snapping and can do so at the time it works best for them
- pressing the Esc key while using the transform box did
reset the transformation, but didn't exit the transform
mode (return to path editing)
* improved layout of some views when the window is resized

* when loading an icon via drag&drop, the file will be remembered
for saving later
* added "Clean Up" feature to "Path" menu
* added "Freeze Transformation" to "Shape" menu (will apply the
current shape transformation onto the path and reset the shape
transformation to identity)
* small cleanup in ShapeListView
* implemented zooming in CanvasView
* added context menu while editing a path
* implemented undo/redo for transforming points
(press T or use context menu)
* added "Split Points" feature (path editing context menu), it will
make two points from one control point
* improved selecting path points with selection rect
* improved SVG import for zuMis BeOS icons (more precise scale)

Quick fix to get it compiling under ZETA. I hope I didn't break it for other platforms.

beginning to check up on gui components:
* added a group of controls to access and manipulate colors (incomplete)

(heavily modified, but originally based on Colors! by Werner Freytag)

* 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

some more "putting things together" for testing:
* add a VectorPath to Document->Icon()->Paths()
* add a Style to the global StyleManager
* actually add a Shape to the Document->Icon()->Shapes()
which uses the style and the path from above

fleshing out of CanvasView:
* use an offscreen bitmap/view to avoid flickering
* use an IconRenderer to render the set Icon
* implement support for zooming

PathManipulator:
* use the conversion from/to Canvas space and View space
in CanvasView (I would have liked to solve this in a
more generic way, so that PathManipulator didn't have to
know CanvasView, but I was not very creative...)

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
