annotate Framework/Scene2D/PanSceneTracker.cpp @ 1370:28eb7106ef44 broker

Changes to GuiAdapter to allow it to work correctly with both new and old Emscripten event selection rules that are defined by the DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR linker flag. Doc has been added to GuiAdapter.cpp, should you require more info on what has been done.
