Rüdiger Timm 0542c76bc2 INTEGRATION: CWS presentationengine01 (1.1.2); FILE ADDED 
2004/10/26 23:43:42 thb 1.1.2.10: #110496# Fixed hefty bug for AA border generation (there's been cases where no viewshapes are left (subset shapes), and then the border rect stayed empty -> DBL_MAX/MIN went into B2DMultiRange calculation); Adapted to explicit alpha bitmap generation at the XGraphicDevice (slide bitmaps don't need alpha, they are opaque. Transparency emulation _does_ need alpha)
2004/10/13 17:56:53 thb 1.1.2.9: #i10000# Gcc doesn't seem to grok (*shared_ptr).*mpFunc any longer (parses it as a function pointer declaration?). Changed to alternative notation
2004/10/08 20:08:15 thb 1.1.2.8: #i34997# Fixed several node state inconsistencies, which led to start/end activities not correctly updating the shapes; added proper updating behaviour to LayerManager (several display-changing cases were missing); fixed SLIDEWIPE for shape transitions; improved docs and structure slightly
2004/08/25 15:56:27 thb 1.1.2.7: #110496# Fixed set effect making shapes visible immediately before the actual effect starts; Fixed wrong handling of deceleration value (especially, acc=0, dec=1 did not work); Fixed wrong to- and by-effect semantics (now according to SMIL spec)
2004/08/23 19:17:16 thb 1.1.2.6: #110496# Implemented remaining attribute animations, fixed some performance problems
2004/08/13 20:33:36 thb 1.1.2.5: #110496# Implemented color animations
2004/08/04 17:21:06 thb 1.1.2.4: #110496# Added various boundary checks, corrected acceleration/deceleration algorithm for one boundary case
2004/07/26 20:40:28 thb 1.1.2.3: #i10000# MSVC really cannot default-initialize enums here
2004/07/26 14:10:09 thb 1.1.2.2: #i10000# Madebind and mem_fn build under Solaris
2004/07/22 19:24:01 thb 1.1.2.1: #110496# Initial revision
