The rest of the ncurses mouse interface. Could use some tweaking, but
basically it works. Define NCURSES_MOUSE_VERSION (preferably to 2 or more) when compiling your program (not PDCurses) to use it. Otherwise, getmouse() is nc_getmouse(), and the BUTTON_ALT etc. labels are different. Apart from that, both interfaces are active all the time, and you can mix and match, although I don't recommend it.
