Kurt Zenker 628820c311 INTEGRATION: CWS canvas02 (1.3.10); FILE MERGED 
2005/10/08 12:57:28 thb 1.3.10.3: RESYNC: (1.3-1.4); FILE MERGED
2005/08/04 21:43:57 thb 1.3.10.2: #i48939# Corrected sprite repaint (opaqueUpdate() don't need to clip, area is guaranteed to cover all full sprites within bound rect); removed plain <long> from textlayout
2005/06/17 23:49:53 thb 1.3.10.1: #i48939# Huge refactoring of canvas; as much functionality as possible is now common in a bunch of shared base classes (input checking, locking, sprite redraw, etc.); added scroll update optimization, transparently to all canvas implementations
