INTEGRATION: CWS canvas02 (1.1.2); FILE ADDED
2005/10/11 15:41:33 thb 1.1.2.5: #i54170# Corrected license headers 2005/09/22 21:00:54 thb 1.1.2.4: #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 14:52:50 thb 1.1.2.3: #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 2005/07/03 20:25:20 thb 1.1.2.2: #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 23:44:42 thb 1.1.2.1: #i48939# The new canvas base classes expect more functionality in delegate members; these are the helper implementations
