2006/04/24 13:25:29 thb 1.6.16.3: #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. 2006/04/12 20:40:08 thb 1.6.16.2: #i37778# Replaced all shared_ptr.get() != NULL places with the more elegant automatic-conversion-to-bool version (at least where the compiler tolerated that) 2006/03/24 18:23:20 thb 1.6.16.1: #i37778# Moved whole slideshow engine from namespace presentation (which conflicts with one of the UNO subnamespaces) to slideshow
