Subject: [PATCH] INTEGRATION: CWS presentationengine01 (1.2.2); FILE MERGED
 2004/10/13 12:14:04 thb 1.2.2.5: #i34997#: Fixed problem with transparency
 bitmap rendering 2004/10/12 14:14:41 thb 1.2.2.4: #i34997# Added support for
 FLOATTRANSPARENCY meta action 2004/07/20 19:09:03 thb 1.2.2.3: #110496#
 Unified include statements; removed external prefix from boost includes
 2004/05/27 20:51:29 thb 1.2.2.2: #110496# Added classification code to all
 TODO/HACK/FIXME comments. There are four categories:  - code quality (C)  -
 performance (P)  - missing functionality (F)  - and missing/incomplete error
 handling (E)

Furthermore, every category has a severity number between
1 and 3 associated, where 1 is lowest and 3 highest
severity
