INTEGRATION: CWS canvas05 (1.1.2); FILE ADDED
2008/06/03 23:52:24 thb 1.1.2.4: Removed extra level of indirection for getting a graphics for a surface; removed some unused code 2008/06/03 11:11:24 thb 1.1.2.3: Cleaned up image debugging stuff; fixed a few d3d debug warnings; fixed one deadlock rendering a bitmap from the same surface to itself; fixed premature ReleaseDC call in GraphicsProvider::getGraphics() 2008/05/23 22:03:45 thb 1.1.2.2: Moving all remaining new files to LGPL 3 2008/01/22 00:25:24 thb 1.1.2.1: #i81092# Making gdiplus and dx canvas more independent
