This is a meta bug used for tracking all runnables in gfx modules that need to be labeled with name and task category.

Please be informed that the use case of nsExpirationTracker has to be labeled as explained in bug 1345387 comment 0. http://searchfox.org/mozilla-central/search?q=nsExpirationTracker&case=false&regexp=false&path=gfx which implicitly apply a timer internally in nsExpirationTracker::CheckStartTimer: http://searchfox.org/mozilla-central/source/xpcom/ds/nsExpirationTracker.h#122

These are most frequent tasks in gfx module which is collected by telemetry in nightly channel : [(u'PVsync::Msg_Notify', 25048721820), (u'PCompositorBridge::Msg_DidComposite', 5624849144), (u'PVRManager::Msg_NotifyVRVSync', 154524944), (u'PTexture::Msg___delete__', 42045325), (u'PVRManager::Msg_NotifyVSync', 28328680), (u'gfxFontCache', 9816622), (u'PuppetWidget::PaintTask', 5980467), (u'PAPZ::Msg_RequestContentRepaint', 5136502), (u'PCompositorBridge::Msg_CompositorUpdated', 123425), (u'PCompositorBridge::Msg_ParentAsyncMessages', 107838), (u'PAPZ::Msg_NotifyAPZStateChange', 45367), (u'PAPZ::Msg_Destroy', 29048), (u'PLayerTransaction::Msg___delete__', 4877), (u'PVsync::Msg_VsyncRate', 1926), (u'PVRManager::Msg_GamepadUpdate', 1640), (u'PAPZ::Msg_SetScrollingRootContent', 213), (u'PVRManager::Msg_UpdateDisplayInfo', 172), (u'PVRLayer::Msg___delete__', 152), (u'PGamepadEventChannel::Msg___delete__', 113), (u'PCompositorBridge::Msg_InvalidateLayers', 89), (u'CompositableForwarder', 89), (u'PAPZ::Msg_NotifyAsyncScrollbarDragRejected', 51), (u'PGamepadEventChannel::Msg_GamepadUpdate', 45), (u'PCompositorBridge::Msg_SharedCompositorFrameMetrics', 9), (u'PCompositorBridge::Msg_ReleaseSharedCompositorFrameMetrics', 6),
