1) log leves are now global wxLOG_ prefixed constants and not wxConfig::enum

Browse Source 
members
2) another variant of wxLogTrace() takes the trace level as argument: this
   allows to filter trace messages from different sources (see wxTraceXXX
   constants)
3) wxLogWindow class added: opens a debug frame which collects all log
   messages
