* XWorkArea.C (work_area_handler): it transpires that
ev->xbutton.button == 0 when the mouse is dragged,
so it cannot be used to initialise x_button_state and
hence FuncRequest.
This patch uses the 'key' that is passed into the function
by xforms to extract this info and so resolve the problem.
* XWorkArea.C (work_area_handler): Pass the mouse button correctly to
dispatch on LFUN_MOUSE_MOTION.
