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
