2006/10/18 10:45:56 thb 1.3.18.3: #142144# Moving to native M_PI_* constants
2006/04/24 13:25:34 thb 1.3.18.2: #i53194# Unified include statements (local headers always have double quotes; external headers angle brackets); reverted EventMultiplexer pause events to shared_ptr; removed EventMultiplexer::removeViewHandler(), since the handler is held weakly, anyway.
2006/03/24 18:23:27 thb 1.3.18.1: #i37778# Moved whole slideshow engine from namespace presentation (which conflicts with one of the UNO subnamespaces) to slideshow
