This function is supposed to set the position with respect to the
client window. If a widget isn't doing this,it's a bug,and should be 
bugzilla.

(Also, the docs need to be improved for
gtk_im_context_set_cursor_location() since they say nothing about
the coordinate system, so that should be in bugzilla as well.)
