INTEGRATION: CWS canvas05 (1.1.2); FILE ADDED

2008/05/23 22:03:43 thb 1.1.2.6: Moving all remaining new files to LGPL 3
2008/05/13 14:51:48 thb 1.1.2.5: removed redundant extra surface from spritecanvas; removed silly conditional that always resolved to true from X11Surface ctor
2008/04/10 21:18:37 mox 1.1.2.4: Making cairo quartz buildable. Some pieces still missing.
2008/04/03 20:12:36 thb 1.1.2.3: Improved the system-dependent passing-around of the OS handles - now much more opaque
2008/04/02 22:56:28 thb 1.1.2.2: Reworked Surface class to abstract interface; changed all manual refcount handling to RAII
2008/03/28 23:38:46 thb 1.1.2.1: Backbuffer-less canvas implementation on top of cairo
