Browse Source 
2005/10/08 12:52:50 thb 1.5.8.3: RESYNC: (1.5-1.6); FILE MERGED
2005/07/03 20:25:14 thb 1.5.8.2: #i48939# Reworked ParametricPolyPolygon, to extract state in an atomic operation; added more state checking 'isXDirty()' methods to canvascustomspritehelper; added various comments and notes
2005/06/17 23:49:48 thb 1.5.8.1: #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
