I don't know if this will be of any help, but this is something I wrote
to get the mouse working in Midnight Commander. Since I had to emulate
the Linux gpm calls, I pass Gpm_Event, but that includes the position
and buttons. I only had to do the up, down, move, and double click. the
chacha with biostime is for the double click logic.
