-- Vertical tabs and titles of dockwidgets are broken
-	Vertical tabs are drawn as yellow rectangle (unfilled) without title
-	Vertical titles of dockwidgets are not rotated
-
-drawComplexControl:
-  CC_SpinBox:
-    Needs to honor stepEnabled
-    
-  CC_ComboBox:
-    Interaction with some of the style option flags (frameless, non-editable, etc.) seems missing.
-    Frameless implemented via subControlRect, but probably best to honor in draw as well.
-    Need to check frame w/designer, at least. Not clear how editable interacts with the SC flags --- 
-    might still pass SC_All?
-
-  CC_ScrollBar:
-    Fallback to QCommonStyle. Should be OK...
-
-  CC_Slider:
-    Looks fine...
-
-  CC_ToolButton:
-    Needs to handle the QStyleOptionToolButton::Arrow feature, though perhaps in CE_ToolButtonLabel?
-
-  CC_TitleBar:
-    Looks OK
-
-  CC_Q3ListView:
-    Looks OK
-
-  CC_GroupBox:
-    No handling (Qt 4.1)
-
-    QCommonStyle breaks it up into PE_IndicatorCheckBox, PE_FrameGroupBox, and PE_FrameFocusRect,
-    along with drawItem text. Need to check with Oxy folks on what their goals are. Probably need at 
-    least a nice placeholder WT for the frame PE, not sure the rest can probably be pushed back to 
-    4.1 or 4.0.x
-
-    Also, need to file a Qt docs bug that drawComplexControl docs don't mention QStyleOptionGroupBox for CC_GroupBox
-    
-  CC_Dial:
-    QCommonStyle does something reasonable. No need to style this, I think, it's (thankfully) hardly ever used.
-
-  CC_MdiControls:
-    No handling (Qt 4.3)
-    Should probably integrate with CC_TitleBar handling somehow, but may need a flag or something to distinguish them, perhaps
-    some sort of bevel/bevelless mode in ButtonKOpt? Definitely a lot of overlap..
-    Side note: only passes in QStyleOptionComplex
-  
-drawControl
-  CE_PushButton
-    QStyleOptionButton::Flat not taken into account (thus the frame is always drawn).
-
-  CE_HeaderSection
-    The sort indicator is the same for both ascending and descending directions.
-
-sizeFromContents:
-    CT_CheckBox: OK
-    CT_ComboBox:
-      Missing! Should compute space much like subControlRect computations do
-
-    CT_Q3DockWindow: Missing, along with other Q3DockWindow primitives. Need to test in 
-      designer to see if it's drawn OK. 
-
-    CT_HeaderSection: Hardcodes icon size instead of using PM_SmallIconSize.
-      Probably should not apply the icon - text margin when there is no icon..
-
-    CT_LineEdit: should probably add it, especially if Oxygen needs it; 
-      unfortunately the QLineEdit internals seem to do some pretty weird stuff, 
-      hardcoding some margins and anything. But, well, a uniform margin model 
-      for this would be nice..
-      see also SE_LineEditContents..
-
-    CT_Menu: OK
-    
-    CT_Q3Header:
-      Missing. Probably share code with CT_HeaderSection, or OK as-is?
-
-    CT_MenuBar, CT_MenuItem: CT_MenuBarItem: OK
-

-    Custom Style Element runtime extension:
-    We reserve one StyleHint to let the effective style inform widgets whether it supports certain
-    string based style elements.
-    As this could lead to number conflicts (i.e. an app utilizing one of the hints itself for other
-    purposes) there're various safety mechanisms to rule out such interference.
-
-    1) It's most unlikely that a widget in some 3rd party app will accidentally call a general
-    QStyle/KStyle styleHint() or draw*() and (unconditionally) expect a valid return, however:
-    a. The StyleHint is not directly above Qt's custom base, assuming most 3rd party apps would
-    - in case - make use of such
-    b. In order to be accepted, the StyleHint query must pass a widget with a perfectly matching
-    name, containing the typical element prefix ("CE_", etc.) and being supported by the current style
-    c. Instead using Qt's fragile qstyleoption_cast on the QStyleOption provided to the StyleHint
-    query, try to dump out a string and hope for the best, we now manipulate the widgets objectName().
-    Plain Qt dependent widgets can do that themselves and if a widget uses KStyle's convenience access
-    functions, it won't notice this at all
-
-    2) The key problem is that a common KDE widget will run into an apps custom style which will then
-    falsely respond to the styleHint() call with an invalid value.
-    To prevent this, supporting styles *must* set a Q_CLASSINFO "X-KDE-CustomElements".
-
-    3) If any of the above traps snaps, the returned id is 0 - the QStyle default, indicating
-    that this element is not supported by the current style.
-
-    Obviously, this contains the "diminished clean" action to (temporarily) manipulate the
-    objectName() of a const QWidget* - but this happens completely inside KStyle or the widget, if
-    it does not make use of KStyles static convenience functions.
-    My biggest worry here would be, that in a multithreaded environment a thread (usually not being
-    owner of the widget) does something crucially relying on the widgets name property...
-    This however would also have to happen during the widget construction or stylechanges, when
-    the functions in doubt will typically be called.
-    So this is imho unlikely causing any trouble, ever.

-    * Runtime element extension, allows inheriting styles to add support custom elements
-    * merges supporting inherit chains
-    * Supposed to be called e.g. in your constructor.
-    *
-    * NOTICE: in order to have this work, your style must provide
-    * an "X-KDE-CustomElements" classinfo, i.e.
-    * class MyStyle : public KStyle
-    * {
-    *       Q_OBJECT
-    *       Q_CLASSINFO ("X-KDE-CustomElements", "true")
-    *
-    *   public:
-    *       .....
-    * }
-    *
-    * @param element The style element, represented as string.
-    * Suggested naming convention: appname.(2-char-element-type)_element
-    * where the 2-char-element-type is of {SH, CE, SE}
-    * widgets in kdelibs don't have to pass the appname
-    * examples: "CE_CapacityBar", "amarok.CE_Analyzer"
-    *
-    * Important notes:
-    * 1) If your string lacks the matching "SH_", "CE_" or "SE_" token the element
-    * request will be ignored (return is 0)
-    * 2) To keep UI coherency, don't support any nonsense in your style, but convince app developers
-    * to use standard elements - if available
