// This is a really painful way to get mouse positions
//
// Windows does not allow a console mode applications easy
// access to windows events. If you want to get at the
// windows message loop you can:
//
// 1) create a window - but this means popping up an
// unnecessary window - or code to make it hide, and 
// means adding windows resources to the executable.
// (or using one of the windows predefined window
// types)
//
// 2) you can access console events as done here, 
// but you don't get the pointer position associated
// with keyboard events.
//
// The way I do it here is to block on keyboard events
// and then get the mouse position. The problem with
// this is that its intrinsically open to race conditions.

// returns 1 if points grabbed
// returns 0 if no points grabbed
// returns -ve if error
