Last patch for X-version (http://www.inp.nsk.su/~bukinm/allegro/au031.gz)
should make it simpler to leave window with mouse, mouse is not
repositioned, if install_mouse was not called, and performance is
improved, because mouse repositioned only once for every 5 mouse
events received from X-server.

In XwinAllegro X-cursor was not repositioned by default, instead
it tried to move Allegro pointer to the position of X-pointer.  It
does not work in this mode now, because there is no border around
Allegro screen and some positions will be unreacheble with mouse.
I have removed this mode in last patch.

Perhaps, I should destroy old window and create new one on
set_gfx_mode just like in XwinAllegro.  Or just move window after
changing size in set_gfx_mode.
