2008/04/21 07:32:16 thb 1.2.94.4: RESYNC: (1.2-1.3); FILE MERGED
2008/04/02 22:56:27 thb 1.2.94.3: Reworked Surface class to abstract interface; changed all manual refcount handling to RAII
2008/03/18 22:00:55 thb 1.2.94.2: Implementing non-backbuffered canvas for cairocanvas as well - reworked to share most of the code
2007/12/20 22:18:56 thb 1.2.94.1: #i81092# #i78888# #i78925# #i79258# #i79437# #i84784# Large canvas rework, completing various areas such as color spaces, bitmap data access, true sprite and non-sprite implementations, and upstreaming the canvas parts of rodos emf+ rendering
