runtime/input_ds3_win.c finds a DualShock 3 through hid.dll and setupapi (loaded at run time), sends it the command
that makes it report, sets its first player light and decodes its reports (runtime/input_ds3.c, tested by
tests/ds3_check) into the pad state, with rumble through its light motor. input.c follows whichever pad was pressed
last when an SDL pad is connected too. ds3 = 1 in nx2navi.ini turns it on: it starts a scan for the controller every
three seconds and opens it read-write, so it stays off unless a player asks for it.
