Subject: [PATCH] INTEGRATION: CWS transogl02 (1.2.4); FILE MERGED 2008/01/15
 10:07:34 fridrich_strba 1.2.4.3: making copy constructor explicit makes the
 class unsuitable for use with stl-ish containers, thorsten dixit 2008/01/14
 20:43:28 fridrich_strba 1.2.4.2: pushPrimitive should take a const reference,
 thorsten dixit 2007/12/10 19:03:53 radekdoulik 1.2.4.1: implemented 5 new
 transitions, fixed flicker problems
