/**
Used for enforcing the redraw calling convention (in preparation for BR2412) in emulator builds.
When enabled this will panic any client calling a CWindowGc draw operation outside a
RWindow::BeginRedraw() / RWindow::EndRedraw() pair (known as non-redraw drawing).
Enable by adding "debug_wserv_exe_EnforceRedrawCallingConvention X" to epoc.ini
where X is either 0 (zero) for "off" or 1 (one) for "on".
Then enable globaly in WServ AutoFlush by defining __AUTO_FLUSH in ../client/client.h
or locally by calling RWsSession::SetAutoFlush(ETrue) for a specific client programatically,
or locally pressing Ctrl-Alt-Shift-F in the emulator.
