2005/09/27 09:22:14 thb 1.3.22.2: #i48939# Removed alpha VDev option from BackBuffer (wasn't used since ages); correctly setting backbuffer size (rounded _up_, like the sprite size itself is calculated, too)
2005/06/17 23:49:47 thb 1.3.22.1: #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
