Ahh, I see. This actually differs from what I suggested: I suggested
introducing a _new_ global variable, let's say "HID *exporter = NULL;",
which would be set by the GUI hid before calling the very first function
of the exporter HID and and then would be unset after. This can happily
live besides the gui swapping draw.c does and needs only 2-3 lines to be
added in each gui HID.
