Mouse location input.

[John Buchanan]

a window rather than in absolute screen coordinates?  The code that I have
now looks like this.

	switch(qread(&val))
		{
		case REDRAW:			/* Reset window offsets */
			getorigin(&xorg,&yorg);
			break;
		case LEFTMOUSE:			/* Get the mouse in window */
			X = getvaluator(MOUSEX) - xorg;
			Y = getvaluator(MOUSEY) - yorg;
			break;
		}

I cannot even imagine the thinking which led to the line drawing occuring
in window coordinates but the mouse tracking only in screen coordinates.
