- Timing view: Added "Cpu Core" tracks when context switches are available. By default the tracks are hidden and can be enabled from Tracks / Context Switches sub-menu. - Timing view: Added "Alt + C" shortcut key to toggle visibility of "Cpu Core" tracks. - Timing view: Added "filter by event type" for Cpu Core tracks. Double click an event in a Cpu Core track highlights all events of same type (same thread) in all Cpu Core tracks. Also fixed the "filter by event type" to fade out / highlight only tracks of same type. #rb Catalin.Dragoiu [CL 16955032 by ionut matasaru in ue5-main branch]
