-- Compatibility shim: Retail moved/removed the old ChatFrame_MessageEventHandler global.
-- Provide gw.ChatFrame_MessageEventHandler so older code keeps working.
gw.ChatFrame_MessageEventHandler = gw.ChatFrame_MessageEventHandler or function(frame, event, ...)
-- Old clients / some builds still have the global:
local g = _G.ChatFrame_MessageEventHandler
if type(g) == "function" then
return g(frame, event, ...)
end

-- Retail: dispatch through the frame’s OnEvent handler (Blizzard chat pipeline)
if frame and frame.GetScript then
local onEvent = frame:GetScript("OnEvent")
if type(onEvent) == "function" then
return onEvent(frame, event, ...)
end

-- Last ditch: don't explode. (Optional)
-- You can omit this if you prefer silent failure.
