INTEGRATION: CWS canvas05 (1.1.2); FILE ADDED

2008/06/09 12:51:47 thb 1.1.2.9: #i88081# Join from CWS impress144 (fixing the dxcanvas crash), extended for the other canvas impls
2008/05/23 22:03:43 thb 1.1.2.8: Moving all remaining new files to LGPL 3
2008/05/13 14:51:47 thb 1.1.2.7: removed redundant extra surface from spritecanvas; removed silly conditional that always resolved to true from X11Surface ctor
2008/04/20 23:36:07 thb 1.1.2.6: Made canvasdemo work again on dev300; made sure GDIPlusUser is always destroyed _last_ (as it kills all other GDIPlus objects); made cairocanvas sensitive to outdev size
2008/04/16 13:47:38 thb 1.1.2.5: Made cairocanvas build on Win32 again
2008/04/04 22:08:33 thb 1.1.2.4: 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)
2008/04/03 20:12:35 thb 1.1.2.3: Improved the system-dependent passing-around of the OS handles - now much more opaque
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
