Done.  Stripped out the overview window stuff.  Also added a little bit
of clipping code to gui_copy_canvas(), but it's incomplete and probably
unnecessary.  Here's version 5.

Ok, I'll submit it as a different patch later.

Incidentally, should the canvas_store_*() and gui_copy_canvas()
functions be in client/gui-win32/graphics.c?  Since struct canvas_store
is declared in client/gui-win32/graphics.h?  Though that'd probably
create some sort of client/graphics_common.h file.
