Clutter Units Macro for converting from device units to #ClutterUnit. @x: int Macro for converting from #ClutterFixed pixels to #ClutterUnit. @x: #ClutterFixed Macro for converting from floating point pixels to #ClutterUnit. @x: float Macro for converting from pixels to #ClutterUnit. @x: int Macro for converting from Pango units to #ClutterUnit. @x: int Macro to ease furture transition #ClutterUnit-based API. This is presently an identity macro, that can be used around integer pixel values passed into clutter functions. When the API is changed to use #ClutterUnit, this macro will be modified to carry out pixel -> #ClutterUnit conversion. @x: int Macro to ease furture transition #ClutterUnit-based API. This is presently an identity macro, that can be used around integer pixel values return from clutter functions. When the API is changed to return #ClutterUnit, this macro will be modified to carry out #ClutterUnit -> pixel conversion. @x: int Macro for conversion from #ClutterUnit values to device unit (currently pixels). @x: #ClutterUnit Macro for conversion of #ClutterUnit value to #ClutterFixed pixel value. @x: #ClutterUnit Macro for conversion of #ClutterUnit value to floating point pixel value. @x: #ClutterUnit Macro for conversion of #ClutterUnit value to int pixel value. @x: #ClutterUnit
