2005/10/08 12:55:59 thb 1.5.2.4: RESYNC: (1.5-1.6); FILE MERGED
2005/09/22 21:00:53 thb 1.5.2.3: #i48939# Employing faster XOR masking for the special case nontransparent, non-alpha bitmap redraw in backbuffer (incidently, that matches the typical slide transition sprite update)
2005/07/21 14:52:49 thb 1.5.2.2: #i48939# Factored out round up/down to integer; removed backend specific methods from base Sprite interface; removed updateScreen overwrite from SpriteCanvasBase (too much backend specifics need to be passed to HW canvases); now passing the target OutputDevice directly via Sprite::redraw() method in VCL canvas; made XFont -> impl font conversion dynamic cast, too; removed the getSpriteTargetSurface crap from SpriteCanvas
2005/06/17 23:49:52 thb 1.5.2.1: #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
2005/04/30 23:56:17 thb 1.4.8.1: #i43238# Largely reworked the update area optimization; now also serving the needs of the RedrawManager to determine whether we can update without backbuffer output preparation; En passant, also fixed a bug that output pos and scale where calculated wrong, if a shape transformation was set but not changed for a sprite redraw
2004/07/23 20:57:15 thb 1.2.2.3: #110496# Made it build under Solaris
2004/07/22 18:40:43 thb 1.2.2.2: #110496# Overhauled sprite redraw algo, to also respect overlapping sprites
2004/04/05 15:58:00 thb 1.2.2.1: Resync with canvas01 changes
