INTEGRATION: CWS canvas05 (1.1.2); FILE ADDED

2008/06/09 08:41:46 thb 1.1.2.7: Replaced screen ptr with screen number, which should be more reliable. Binned manual fill-out of X11SysData structs in favor of ctor
2008/05/23 22:03:44 thb 1.1.2.6: Moving all remaining new files to LGPL 3
2008/04/28 23:20:27 thb 1.1.2.5: Using the screen ptr from the sysdata struct, to avoid BadMatch errors
2008/04/04 22:08:34 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)
2008/04/04 09:00:13 thb 1.1.2.3: Merging emf+ changes for dx canvas
2008/04/03 16:02:26 thb 1.1.2.2: Merged in cairoquartz01 changes, reworked into the polymorphic Surface concept now
2008/04/02 22:56:28 thb 1.1.2.1: Reworked Surface class to abstract interface; changed all manual refcount handling to RAII
