INTEGRATION: CWS canvas05 (1.1.2); FILE ADDED
2008/06/09 12:51:47 thb 1.1.2.5: #i88081# Join from CWS impress144 (fixing the dxcanvas crash), extended for the other canvas impls 2008/05/23 22:03:43 thb 1.1.2.4: Moving all remaining new files to LGPL 3 2008/04/04 22:08:33 thb 1.1.2.3: Fixed output of bezier polygons for cairo; fixed missing surfaces here and there; removed useless refcounted SurfaceProvider arguments (that lead to premature canvas death, as called during ctor) 2008/04/02 22:56:26 thb 1.1.2.2: Reworked Surface class to abstract interface; changed all manual refcount handling to RAII 2008/03/28 23:38:45 thb 1.1.2.1: Backbuffer-less canvas implementation on top of cairo

Have to mixin the SurfaceProvider before deriving from

we cannot specify non-IDL types as WeakComponentImplHelperN

template args, and furthermore, don't want to derive

::canvas::CanvasBase directly from

SurfaceProvider (because derivees of
|

::canvas::CanvasBase have to explicitely forward the

XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)

anyway).
